6 v T General Requirements for Using the FA-M3 Avoid installing the FA-M3 in the following locations: - Where the instrument will be exposed to direct sunlight, or where the operating temperature exceeds the range 0 C to55 C (0 F to 131 F). - Where the relative humidity is outside the range 10 to 90%, or where sudden temperature changes may occur and cause condensation. - Where corrosive or flammable gases are present. - Where the instrument will be exposed to direct mechanical vibration or shock. - Where the instrument may be exposed to extreme levels of radioactivity. Use the correct types of wire for external wiring: - Use copper wire with temperature ratings greater than 75 C. Securely tighten screws: - Securely tighten module mounting screws and terminal screws to avoid problems such as faulty operation. - Tighten terminal block screws with the correct tightening torque as given in this manual. Securely lock connecting cables: - Securely lock the connectors of cables, and check them thoroughly before turning on the power. Interlock with emergency-stop circuitry using external relays: - Equipment incorporating the FA-M3 must be furnished with emergency-stop circuitry that uses external relays. This circuitry should be set up to interlock correctly with controller status (stop/run). Ground for low impedance: - For safety reasons, connect the [FG] grounding terminal to a Japanese Industrial Standards (JIS) Class 3 Ground. For compliance to CE Marking, use cables such as twisted cables which can ensure low impedance even at high frequencies for grounding. Configure and route cables with noise control considerations: - Perform installation and wiring that segregates system parts that may likely become noise sources and system parts that are susceptible to noise. Segregation can be achieved by measures such as segregating by distance, installing a filter or segregating the grounding system. Configure for CE Marking Conformance: - For compliance with CE Marking, perform installation and cable routing according to the description on compliance to CE Marking in the Hardware Manual (IM34M6C11-01E). Keep spare parts on hand: - Stock up on maintenance parts including spare modules, in advance.

7 vi Discharge static electricity before operating the system: - Because static charge can accumulate in dry conditions, first touch grounded metal to discharge any static electricity before touching the system. Never use solvents such as paint thinner for cleaning: - Gently clean the surfaces of the FA-M3 with a cloth that has been soaked in water or a neutral detergent and wringed. - Do not use volatile solvents such as benzine or paint thinner or chemicals for cleaning, as they may cause deformity, discoloration, or malfunctioning. Avoid storing the FA-M3 in places with high temperature or humidity: - Since the CPU module has a built-in battery, avoid storage in places with high temperature or humidity. - Since the service life of the battery is drastically reduced by exposure to high temperatures, take special care (storage temperature should be from 20 C to 75 C). - There is a built-in lithium battery in a CPU module and temperature control module which serves as backup power supply for programs, device information and configuration information. The service life of this battery is more than 10 years in standby mode at room temperature. Take note that the service life of the battery may be shortened when installed or stored at locations of extreme low or high temperatures. Therefore, we recommend that modules with built-in batteries be stored at room temperature. Always turn off the power before installing or removing modules: - Failing to turn off the power supply when installing or removing modules, may result in damage. Do not touch components in the module: - In some modules you can remove the right-side cover and install ROM packs or change switch settings. While doing this, do not touch any components on the printed-circuit board, otherwise components may be damaged and modules may fail to work.

14 1. Overview 1-1 High-speed Counter Modules are designed to connect with a sensor, such as an incremental encoder, to receive and count a high-speed signal of up to 100 kpps. They exchange data through I/O relays and registers with the CPU module of the FA-M3 controller. As noted here, the counter modules are available in two models, as shown below, depending on the number of counting channels and the applicable controller. Features Model Number of Counting Channels F3XP01-0H 1 F3XP02-0H 2 - The 32-bit counter of the modules can count a signal as fast as 100 kpps. - Each channel has two external matching outputs, allowing two setpoints to be defined. - An F3XP02-0H module can be configured so that one channel has four matching outputs. (In this configuration, the other channel cannot have any matching outputs.) - The modules have three counting modes phase difference mode, pulse-anddirection mode and addition/subtraction mode and, therefore, can be connected to various types of sensors. - In the phase difference mode, the modules are capable of twofold or quadruple multiplication, enabling resolution to be improved. Application Example This application quickly positions the axle of a motor using the two external matching outputs on channel 1 of each of the modules. Setting:Configure setpoints 1 and 2 on channel 1 as shown below. Setpoint 1: pulse-based value for a low-speed command Setpoint 2: pulse-based value for a stop command Operation: When a given output relay of a contact output module (for example, F3YD32 module) turns on, the motor starts running at high speed. When the counter value matches setpoint 1, the motor slows down; when it matches setpoint 2, the motor stops.

36 3. Functions of the Function Switch 3.1 Operation Mode There are two types of operation mode: (1) Linear mode (2) Ring mode The operation mode is set by bit number 1 of the function switch. See Section Linear Operation In linear operation, the counter value varies between $ and $FFFFFFFF ($ denotes a hexadecimal number). When the counter value is $ and a down-pulse is entered, underflow occurs and the counter value $ remains unchanged. When the counter value is $FFFFFFFF and an up-pulse is input, overflow occurs and the counter value $FFFFFFFF remains unchanged. An interrupt can be generated when a counter overflow/underflow occurs. When the operation mode is set to Linear operation, use the initial value $FFFFFFFF as the maximum ring value. When a value other than $FFFFFFFF is set as the maximum ring value, either reset the module or set it to $FFFFFFFF again. Counter value $ $FFFFFFFF UP DOWN Underflow Overflow Figure 3.1 Linear Operation When an underflow or overflow occurs, the counter overflow/underflow input relay becomes 1 (ON). To determine whether a counter overflow or underflow has occurred, read the input relay status corresponding to each channel as shown in Table 3.1. Table 3.1 Input Relay for Counter Overflow/Underflow Input Relay Number *1 Relay Contents Relay Status = 1 (ON) Relay Status = 0 (OFF) X 05 Counter overflow/underflow for channel 1 Occurred Not occurred X 06 *2 Counter overflow/underflow for channel 2 Occurred Not occurred *1: is the slot number where the module is installed. *2: Not applicable to F3XP01-0H.

37 3-2 T Ring Operation For ring operation, the counter value varies between $ and the maximum ring value. If a down-pulse is entered when the counter value is $ , the counter value becomes the maximum ring value. Moreover, if an up-pulse is entered when the counter value is the maximum ring value, the counter value becomes $ When the operation mode is set to Ring operation, you can set any arbitrary value as the ring maximum value (see Section 4.3). Max. value $0 DOWN UP Figure 3.2 Ring Operation

38 Counter Modes There are five types of counter mode: - Phase difference x 1 mode - Phase difference x 2 mode - Phase difference x 4 mode - Pulse-and-direction mode - Addition/subtraction mode The counter mode is set by bit numbers 2, 3, 4, 5 of the function switch. See Section 2.3 of this manual. T PhaseDifferencex1Mode When phase A leads phase B by 90, it increments the counter at the rising edge of phase A. When phase A lags behind phase B by 90, it decrements the counter at the falling edge of phase A. Counter value N N+1 N N 1 Phase A Phase B Figure 3.3 Counting in Phase Difference x1multiplicationmode T PhaseDifferencex2Mode When phase A leads phase B by 90, it increments the counter at the rising and falling edges of phase A.

40 3.3 Counter Enable/Disable 3-5 The module can be set to either count (counter enable) or not count (counter disable) input pulses. When the counter is disabled, the comparison operation (see Section 5.1) explained later is not performed. Table 3.2 Enable/Disable Status List Counter Counter Disable Counting operation Run Stop Comparison operation Run Stop (maintain the status) External matching output Setting allowed Setting allowed signal enable/disable Preset Execution possible Execution possible Register access Allowed Allowed Module reset Allowed Allowed The procedures for setting counter enable/disable are explained below. If the counter is to be always enabled without performing the following setting procedure, turn ON bit number 6 of the function switch. (See Section 2.3 of this manual.) Setting with an external input signal The counter is enabled if the external counter enable input signal (EN) is turned ON, and the counter is disabled if it is turned OFF. Setting with a program The counter is enabled if the output relay corresponding to each channel shown in Table 3.3 is turned ON (1), and the counter is disabled if it is turned OFF (0). Table 3.3 Output Relay for Counter Enable/Disable Output Relay Number *1 Relay Contents Relay Status =1(ON) Relay Status = 0 (OFF) XVVV33 Counting status for channel 1 Enabled Disabled XVVV36 *2 Counting status for channel 2 Enabled Disabled *1: VVVis the slot number where the module is installed. *2: Not applicable to F3XP01-0H. TIP When both methods mentioned above are used, the counter is enabled if it is enabled by either method. The status of the external counter enable input signal (EN) of each channel is obtained by reading the input relay shown in Table 3.4. Table 3.4 Input Relay for Counter Enable Input Signal Input Relay Number *1 Relay Contents Relay Status Relay Status =1(ON) = 0 (OFF) XVVV17 External counter enable input signal for channel 1 ON OFF XVVV8 *2 External counter enable input signal for channel 1 ON OFF *1: VVV is the slot number where the module is installed. *2: Not applicable to F3XP01-0H.

41 3-6 CAUTION To enter a down count during counter disable (see the figure below), reset the module using a program immediately before enabling the counter. (For more details, see Section 5.2, Resetting the Module.) All the registers and counter values within the module will be initialized. Perform setting again if necessary. Example of Phase Difference x 4 Multiplication Phase A ON OFF Phase B ON OFF Enable ON OFF Disable status

42 External Matching Output Mode CAUTION Only the external matching output 2-point mode can be used for F3XP01-0H. External matching output 4-point mode cannot be used. There are two types of external matching output mode: external matching output 2-point mode and external matching output 4-point mode. In this module, each channel has two external matching outputs. External matching output of channel 1 can be converted into 4-point mode by using the external matching outputs of channel 2 for channel 1. External matching output 2-point mode As per the original function of this module, the external matching output for every channel has two points. External matching output 4-point mode This can be used in F3XP02-0H. The External matching output for channel 1 is 4-point and that for channel 2 is 0-point (Nil). In addition to the counting operation, channel 1 performs the comparison operation with four set points and it has a 4-point external matching output. The data position number of the set point, the input relay number showing the result of the comparison operation, and the output relay number for performing reset or enable/disable for the two points added to channel 1 are the same as that for the original channel 2. Counting operation for channel 2 is still performed (counter value can also be read) but the comparison operation and external matching output for channel 2 are absent. To set the external matching output 4-point mode, turn on bit number 7 of the function switch for channel 1. (See Section 2.3). 3.5 Filter The filter removes noise in the external input signals (phase A, phase B, preset and enable of each channel). For proper functioning of the filter, change the characteristics of the filter using bit number 8 of the function switch for each channel. When the maximum frequency of phase A, phase B or external preset signal exceeds 50 kpps, bit number 8 is turned OFF and when it is below 50 kpps, bit number 8 is turned ON. (See Section 2.3).

T Changing (Writing) the Counter Value Changing the counter value means setting it to any value between $ to $FFFFFFFF. Any arbitrary value is written in the register at the data position numbers shown in Table 4.3. The counter value cannot be changed using a BASIC program. Table 4.3 Data Position Number for Changing the Counter Value Channel 1 Channel 2* Ladder 1 2 *: Not applicable to F3XP01-0H. T Resetting the Counter Value Resetting the counter value means setting it to $ There are no special instructions for resetting the counter value. Perform resetting using 'preset' mentioned later (see Section 4.4) or by using 'Changing the counter value' mentioned above. How to reset the counter value is explained below. Resetting the counter value by preset Set the preset value to $ and execute preset. Resetting the counter value by changing the counter value To change the counter value, write $ to the register.

46 4.2 Set Value 4-3 The set value is the standard value used for comparison with the counter value. Two set values (set value 1 and set value 2) can be set for channel 1 in F3XP01-0H and for channel 1 and channel 2 in F3XP02-0H, respectively. Setting is carried out by writing the set value in the register. The set value can also be read from the register. Set values are written and read to/from the register at the data position numbers shown in Table 4.4. Table 4.4 Data Position Number for Set Value Channel 1 Channel 2* Set value 1 Set value 2 Set value 1 Set value 2 Ladder BASIC *: Do not perform setting for F3XP01-0H. 4.3 Maximum Ring Value The maximum ring value is the maximum counter value when the operation mode is ring operation (See Section 3.1). The maximum ring value can be set for channel 1 in F3XP01-0H and for channel 1 and channel 2 in F3XP02-0H, respectively. Perform setting by writing the maximum ring value to the register. The maximum ring value can also be read from the register. The maximum ring value is written and read to/from the data position number shown in Table 4.5. Table 4.5 Data Position Number of Maximum Ring Value Channel 1 Channel 2* Ladder BASIC 9 11 *: Do not perform setting for F3XP01-0H.

47 4.4 Preset Value Presetting means setting any arbitrary value already written in the register to the counter. This value is called the preset value. Preset values can be set for channel 1 in F3XP01-0H and for channel 1 and channel 2 in F3XP02-0H, respectively. Preset values can also be read from the register. Preset values are read from the registers at the data position numbers shown in Table Table 4.6 Data Position Number for Preset Value Channel 1 Channel 2* Ladder BASIC *: Do not perform setting for F3XP01-0H. Setting with an external input signal 1.

48 5. Operation of the Module 5.1 Comparison Operation 5-1 The comparison operation compares the set value and the counter value and reflects the result in the input relay. As a result of the comparison, if the set value and the counter value is the same, the external matching output signal (OUT1, OUT2) turns ON. Moreover, an interrupt can be generated when the external matching output signal is 'ON'. Result of Comparison The result of the comparison is reflected in the input relay. To determine whether the counter value is larger than, smaller than or equal to the set value, read the corresponding input relay.

External Matching Output Signal As a result of comparison, if the set value and the counter value are the same, the corresponding input relays X 01 to X 04 (X 01 to X 02 for F3XP01-0H) turns ON (1). At the same time the external matching output signals (OUT1, OUT2) turns ON. For each channel, the external matching output signals are External Matching Output 1 signal (OUT1) corresponding to set value 1 and External Matching Output 2 signal (OUT2) corresponding to set value 2. Reset Input relays X 01 to X 04 (X 01 to X 02 for F3XP01-0H) and the external matching output signal are of the latch type. Once the relay is turned ON, it stays ON until the corresponding output relay is set to ON (1). To reset the relay, turn ON (1) the output relay corresponding to each channel shown in Table 5.2.
