4 Mechanical Brake Control Application SECTION I MECHANICAL BRAKE CONTROL APPLICATION 1-1 Introduction Select the Mechanical Brake Control Application in menu M6. The Mechanical Brake Control Application is typically used in applications where brake control is needed. The hardware can be any Avtron ACCel500 frequency converter. In closed loop motor control mode an encoder option board is required (Avtron P/N ). All outputs are freely programmable. Digital input functions are freely programmable to any digital input. Start forward and reverse signals are fixed to input DIN1 and DIN2 (see next page). Additional functions: Programmable Start/Stop and Reverse signal logic Reference scaling One frequency limit supervision Second ramps and S-shape ramp programming Programmable start and stop functions DC-brake at stop One prohibit frequency area Programmable U/f curve and switching frequency Autorestart Motor thermal and stall protection: Programmable action; off, warning, fault Mechanical brake control related parameters 8 digital speed references selected by 3 digital inputs IMPORTANT: Configuration information in this manual is provided to assist users in designing their own operational/functional schemes. It is deemed to be correct, however, if any errors or omissions exist, Avtron and/or Avtron representatives will not be liable to provide warranty on-site support. If one is designing his own configuration, or using one of the examples, it is highly recommended to test the operation prior to putting the drive into production. 1-1

6 Programming Principle of the Digital Input Signals SECTION II PROGRAMMING PRINCIPLE OF THE DIGITAL INPUT SIGNALS The programming principle of the input signals in the Mechanical brake control Application as well as in the Multipurpose Control Application (and partly in the other applications) is different compared to the conventional method used in other Avtron ACCel500 applications. In the conventional programming method, Function to Terminal Programming Method (FTT), you have a fixed input that you define a certain function for. The applications mentioned above, however, use the Terminal to Function Programming method (TTF) in which the programming process is carried out the other way round: Functions appear as parameters that the operator defines a certain input for (see Figure 2-1). Figure 2-1. Basic Principle of the Terminal to Function Programming Method (TTF) NOTE A constant value can be given to an input signal. Value 0.1 is a constant FALSE and values from 0.2 through 0.10 are constant TRUE (see Figure 2-1). 2-1

7 Programming Principle of the Digital Input Signals 2-1 Defining an Input for a Certain Function On Keypad Connecting a certain function (input signal) to a certain digital input is done by giving the parameter an appropriate value. The value is formed of the Board slot on the ACCel500 control board (see ACCel500 User's Manual, Chapter 4) and the respective signal number, see below. Function name Terminal type Slot Terminal number Example: You want to connect the digital input function Fault Reset (parameter ) to a digital input A.3 on the basic I/O board located in Slot A. First find the parameter on the keypad. Press the Menu button right once to enter the edit mode. On the value line, you will see the terminal type on the left (DigIN) and on the right, digital input where function is connected. When the value is blinking, hold down the Browser button up or down to find the desired board slot and signal number. The program will scroll the board slots starting from 0 and proceeding from A to E and the I/O numbers from 1 to 10. Once you have set the desired value, press the Enter button once to confirm the change. > 2-2

8 Programming Principle of the Digital Input Signals 2-2 Defining a Certain Function with ADDAPT ACC Programming Tool If you use the ADDAPT ACC programming tool for assigning parameter values, you will have to establish the connection between the function and input/output in the same way as with the control panel. Just pick the address code from the drop-down menu in the Value column (see Figure 2-2). Figure 2-2. Screenshot of ADDAPT ACC Programming Tool; Entering the Address Code NOTE Two inputs signals can be connected to same digital input. Use this feature very cautiously. 2-3

The maximum value for parameters and is 320 Hz. The software will automatically check the values of parameters , , , , and Acceleration time Deceleration time 1 These limits correspond to the time required for the output frequency to accelerate from the zero frequency to the set maximum frequency (par ) Current limit This parameter determines the maximum motor current from the frequency converter. To avoid motor overload, set this parameter according to the rated current of the motor. The current limit is 1.5 times the rated current (I L ) by default Nominal voltage of the motor Find this value U n on the rating plate of the motor. This parameter sets the voltage at the field weakening point (parameter 2.6.5) to 100% x U nmotor Nominal frequency of the motor Find this value f n on the rating plate of the motor. This parameter sets the field weakening point (parameter 2.6.4) to the same value Nominal speed of the motor Find this value n n on the rating plate of the motor Nominal current of the motor Find this value I n on the rating plate of the motor Motor cos phi Find this value cos phi on the rating plate of the motor. 5-1

28 The selections 4 to 6 shall be used to exclude the possibility of an unintentional start when, for example, power is connected, re-connected after a power failure, after a fault reset, after the drive is stopped by Run Enable (Run Enable = False) or when the control place is changed. The Start/Stop contact must be opened before the motor can be started. 4 DIN1: closed contact = start forward (Rising edge required to start) DIN2: closed contact = start reverse (Rising edge required to start) 5 DIN1: closed contact = start (Rising edge required to start) open contact = stop DIN2: closed contact = reverse open contact = forward 6 DIN1: closed contact = start (Rising edge required to start) open contact = stop DIN2: closed contact = start enabled open contact = start disabled and drive stopped if running Reference offset for current input 0 No offset 1 Offset 4 ma ( living zero ), provides supervision of zero level signal.

37 5-4 DRIVE CONTROL Acceleration/Deceleration ramp 1 shape Acceleration/Deceleration ramp 2 shape The start and end of acceleration and deceleration ramps can be smoothed with these parameters. Setting value 0 gives a linear ramp shape which causes acceleration and deceleration to act immediately to the changes in the reference signal. Setting value 0.1 to 10 seconds for this parameter produces an S-shaped acceleration/deceleration. The acceleration time is determined with parameters 2.1.3/2.1.4 (2.4.3/2.4.4). [Hz] 2.1.3, (2.4.3, 2.4.4) (2.4.2) (2.4.2) [t] UD012K20 Figure Acceleration/Deceleration (S-shaped) Acceleration time Deceleration time 2 These values correspond to the time required for the output frequency to accelerate from the zero frequency to the set maximum frequency (par ). These parameters give the possibility to set two different acceleration/deceleration time sets for one application. The active set can be selected with the programmable signal DIN3 (par ). 5-14

38 2.4.5 Brake chopper When the frequency converter is decelerating the motor, the inertia of the motor and the load are fed into an external brake resistor. This enables the frequency converter to decelerate the load with a torque equal to that of acceleration (provided that the correct brake resistor has been selected). 0 = No brake chopper used 1 = Brake chopper in use when running 2 = External brake chopper 3 = Used when stopped/running 4 = Brake chopper in use when running, no test Start function Ramp: 0 The frequency converter starts from 0 Hz and accelerates to the set reference frequency within the set acceleration time. (Load inertia or starting friction may cause prolonged acceleration times). Flying start: 1 The frequency converter is able to start into a running motor by applying a small torque to motor and searching for the frequency corresponding to the speed the motor is running at. Searching starts from the maximum frequency towards the actual frequency until the correct value is detected. Thereafter, the output frequency will be increased/decreased to the set reference value according to the set acceleration/deceleration parameters. Use this mode if the motor is coasting when the start command is given. With the flying start it is possible to ride through short mains voltage interruptions Stop function Coasting: 0 The motor coasts to a halt without any control from the frequency converter, after the Stop command. Ramp: 1 After the Stop command, the speed of the motor is decelerated according to the set deceleration parameters. If the regenerated energy is high it may be necessary to use an external braking resistor for faster deceleration. Normal stop: Ramp/ Run Enable stop: coasting 2 After the Stop command, the speed of the motor is decelerated according to the set deceleration parameters. However, when Run Enable is selected (e.g. DIN3), the motor coasts to a halt without any control from the frequency converter. Normal stop: Coasting/ Run Enable stop: ramping 3 The motor coasts to a halt without any control from the frequency converter. However, when Run Enable signal is selected (e.g. DIN3), the speed of the motor is decelerated according to the set deceleration parameters. If the regenerated energy is high it may be necessary to use an external braking resistor for faster deceleration. 5-15

Acceleration and deceleration times 2 (P2.4.3 and P2.4.4) are used below this frequency when motorized potentiometer is selected x PROHIBIT FREQUENCIES Prohibit frequency area; Low limit Prohibit frequency area; High limit In some systems it may be necessary to avoid certain frequencies because of mechanical resonance problems. With these parameters it is possible to set limits for the "skip frequency" region. See Figure Figure Prohibit frequency area setting. 5-16

40 Acc/dec ramp speed scaling ratio between prohibit frequency limits Defines the acceleration/deceleration time when the output frequency is between the selected prohibit frequency range limits (parameters and 2.5.2). The ramping speed (selected acceleration/ deceleration time 1 or 2) is multiplied with this factor. For example, value 0.1 makes the acceleration time 10 times shorter than outside the prohibit frequency range limits.

42 Load Float Bit ID HI bit will enable Load Float function. When enabled the drive will maintain motor speed set at parameter :Load Float Spd after the drive looses its run command and ramps down to load float speed. Drive will hold speed until either run is reenergized or Load Float Timer expires (P2.4.27) Load Float Time Constant Period of time the drive will have the motor maintain speed set at parameter :Load Float Spd. Period of time is in seconds Load Float Speed Speed of motor maintained when run when parameter :LD Float Bit ID is enabled, the drive s speed ramps down, and the run command is removed LF Trq Prv Spd Not used/future addition Reverse End Stop Input ID Disables drive run in reverse direction when LOW. Normally used for end of travel stop limits input Forward End Stop Input ID Disables drive run in the forward direction when LOW. Normally used for end of travel stop limits input Brake Close Timer After the run command is removed, the drive ramps the motor to zero, and the brakes are commanded to close, this timer makes the brake slip logic wait in order to allow the brakes to close before the logic starts monitoring the brake. Time is in seconds Enable Brake Slip Fault HI bit (1 = Yes) enables the open brake detection logic. After the drive has ramped the motor to zero, the run command is low, and the Brake Close Timer has expired, the open brake logic will compare V1.16:Encoder Speed to P2.4.34:Brake Slip Freq. If V1.16 exceeds P2.4.34, the logic will determine that the brake is open when it shouldn t. A detected open brake will cause the parameter programmed to P2.4.38:Brk Slip DOUT ID to toggle Brake Slip Frequency Speed setpoint that V1.16:Encoder Speed has to cross for the open brake logic to detect an open brake. 5-19
