Compact Actuator DRL Series The DRL Series of compact linear motion actuators use a new 5-phase stepping motor which incorporates a ball screw. These are combined with 5-phase 24 VDC microstepping drivers with photocoupler inputs for extremely precise positioning. Compact Design The compact design of the DRL actuator allows for the elimination of extra parts such as couplings belts and pulleys. The DRL actuator is a self-contained package consisting of a stepping motor with a hollow shaft rotor connected to a ball screw nut. Rotation of the nut initiates movement of the actual ball screw. without Guide Applications Drive mechanism for a micrometer head X-Y stage with Guide Focusing a CCD camera Frame Size 1.1 inch (28 mm) DRL28P 1-3 Max.

Driving a pump actuator device Silicon wafer pin lifter DRL Few Componerts, Simple Mechanism Microstepping Drivers The driver features a microstepping mechanism that electronically divides the basic step angle of the motor, thus enabling high resolution and low-vibration operation at low speeds. Reliable Design and Structure The drive mechanism employs a 5- phase stepping motor with ball screw. The hollow rotor shaft incorporates large bore bearings for the direct handling of thrust loads. Minimizing the number of parts involved in linear conversion results in higher reliability.

The thrust force varies, depending on the loaded mass and acceleration. 4 The maximum load moment is measured from the center of the load-mounting taps on the linear-guide side. 5 The repetitive positioning accuracy is measured at a specified temperature under a specified load. Refer to Repetitive Positioning Accuracy of DRL Series on page F-51 to ensure the repetitive positioning accuracy stated in the specification sheet. 6 The repetitive positioning accuracy is measured at a specified temperature and load. If footnote or is not indicated, then the repetitive positioning accuracy values are identical. Repetitive positioning accuracy is measured at the end of the guide. Repetitive positioning accuracy is measured on the linear-guide. Note: Use the actuator in conditions where its surface temperature will not exceed 194 F (9 C). The actuator may give off a significant amount of heat, depending on the conditions of operation.

When Vo is equal to 5 VDC, the external resistances R1 and R2 are not necessary. When Vo is above 5 VDC, connect R1 and R2 to keep the current as follows: Pulse, Rotation Direction: 1 ma to 2 ma max. All Windings OFF, Resolution Select: 1 ma to 15 ma max. Keep the output signal voltage Vo between 5 VDC and 24 VDC. When Vo is equal to 5 VDC, the external resistance R3 is not necessary. When Vo is above 5 VDC, connect R3 to keep the current below 1 ma max. Use twisted-pair wire of AWG 24 to AWG 22 and 6.6 feet (2 m) or less in length for the signal line. Suitable wire size for the TB1, TB2 and TB3 terminal block is between AWG2 and 26. Use AWG 2 for power supply lines. Use spot grounding to ground the driver and external controller. Signal lines should be kept at least 3.94 inches (1 cm) away from power lines (power supply lines and motor lines). Do not bind the signal line and power line together. If noise generated by the motor lead wires cause a problem, try shielding the motor lead wires with conductive tape or wire mesh. Incorrect connection of DC power input will lead to driver damage. Make sure that the polarity is correct before turning the power on. Description of Input/Output Signals Pulse Input and Rotation Direction Input 1-Pulse Input Mode Pulse Signal "Pulse" signal is input to the Pulse terminal. When the photocoupler state changes from "ON" to "OFF", the screw shaft moves one step. The output direction of a screw shaft is determined by the rotation direction signal. Rotation Direction Input The "Rotation Direction" signal is input to the D/CCW terminal. A "photocoupler ON" signal input commands the screw shaft to move forward. A "photocoupler OFF" signal input commands the screw shaft to move backward. TB1 TB3 + - + - + - + 1 2 1 2 3 4 5 1 2 3 4 5 6 9-1 + - 7 8 22 Ω 22 Ω 47 Ω 47 Ω 2-Pulse Input Mode CW Pulse Signal "Pulse" signal is input to the P/CW terminal. When the photocoupler state changes from "ON" to "OFF", the screw shaft moves one step forward. CCW Pulse Signal "Pulse" signal is input to the D/CCW terminal. When the photocoupler state changes from "ON" to "OFF", the screw shaft moves one step backward. All Windings Off (A.W. OFF) Input When the "All Windings Off" (A.W. OFF) signal is in the "photocoupler ON" state, the current to the motor is cut off and motor torque is reduced to zero. This signal is used when moving the motor by external force or manual home positioning. Resolution Select (C/S) Input When the "Resolution Select" signal is in the "photocoupler OFF" state, the resolution set by step resolution select switch DATA1 is selected. When the "Resolution Select" signal is in the "photocoupler ON" state, the resolution set by step resolution select switch DATA2 is selected. This signal can be used to change the motor speed or amount of rotation without altering the input pulses. Excitation Timing (TIMING) Output When the motor-excitation state is in the excitation home position (step []), the driver switches on the timing output. The motor-excitation state is reset to the excitation home position when the power supply is switched on. The timing output comes on every particular amount (see the chart below) of the screw shaft movement, being synchronized with the pulse input. When the pulse signals are input at an integer multiple of the number of pulses required for the screw shaft to move this particular amount (see the chart below), it is possible to check whether or not the driver is operating normally by monitoring the timing output. DRL28 DRL42 DRL6 Movement Distance of the Screw Shaft [inch (mm)].79 (.2).16 (.4).31 (.8) Notes: When using the timing output, stop the motor s output shaft at an integer multiple of a particular amount (see the chart above). When switching the resolution using the C/S (resolution switch) input, do this with the motor stopped and the timing output on.

Resolution Selection The motor speed and step distance can be changed without changing the input pulse frequency by switching the resolution switch. The resolution is set with resolution setting switches DATA1 and DATA2. DATA1 and DATA2 each have 16 settings from which one resolution each can be selected. The resolution that can be set are shown in the table below. DATA1 and DATA2 are set to the scale corresponding to the resolution selected for each. The resolution is changed with the resolution select signals. Photocoupler "ON": The resolution set with DATA1 is selected. Photocoupler "OFF": The resolution set with DATA2 is selected.

MOTOR Adjusting the Current Adjusting the Motor Current Use the "RUN" potentiometer to decrease the current and suppress the temperature rise in the motor/driver, or when there is sufficient motor torque and you want to suppress vibration by lowering the current. Use the "STOP" potentiometer to readjust the current at motor standstill in relation to the holding-brake force. Factory Settings Running current: Rated current Current at motor standstill: Approx. 5% of rated current Follow the procedure below to adjust the motor current. z Connecting an Ammeter Connect a DC ammeter as illustrated below. Connect an ammeter between pin of TB2 connector and the actuator. Set all driver input signals to the "photocoupler OFF" state. CW Input: Forward b CCW Input: Backward a Actuator Note: Do not input pulse signals.

Set the current-checking switch to the "photocoupler ON" state. Keep other signals in the "photocoupler OFF" state. 2. Turn on the power to the driver. 3. Use the "RUN" potentiometer to adjust the motor's running current. 4. When the power is turned on, the value measured by the ammeter represents the total current in two phases through the blue motor lead wire. The current for one phase is equivalent to one-half the ammeter value. (Example: To set the current to 1. A/phase, adjust the current level until the ammeter reads 2. A.) 5. When the running current has been adjusted, set the current-checking switch back to the "photocoupler OFF" state. Notes: Be sure to use the motor at the rated current or below. Adjusting the running current will also change the current at standstill. c Adjusting the Current at Motor Standstill To adjust the current at motor standstill, follow the procedure below: 1. Set the current-checking switch to the "photocoupler OFF" state. Keep other signals in the "photocoupler OFF" state. 2. Turn on the power to the driver. 3. Use the "STOP" potentiometer to adjust the motor's running current. 4. When the power is turned on, the value measured by the ammeter represents the total current in two phases through the blue motor lead wire. The current for one phase is equivalent to one-half the ammeter value. (Example: To set the current to 1. A/phase, adjust the current level until the ammeter reads 2. A.) Holding Torque [oz-in (N m)] Maximum Holding Torque [oz-in (N m)] Current at Standstill [A] Motor rated current [A] Notes: Always set the running current first, turn off the driver power and turn it back on, and then set the current at standstill. Setting the running current after current at standstill may change the current setting at standstill. Setting the current at motor standstill too low may affect the starting of the actuator or the position-holding action.
