The voltage of pulse and rotation direction input to the PLS input and DIR. input
shall be 5 VDC. If the voltage exceeds 5 VDC, connect an external resistor to limit
the input current to nearly 10 mA.

V: Pulse voltage
Use an input-pulse signal with a waveform having a sharp rise and fall, as shown in
the figure. The figure shows the voltage levels of pulse signals.

• C.OFF (All windings off) input
Use the signal only when the output table must be rotated manually for position
adjustment.
• When the C.OFF input is turned “ON,” the driver will shut off the output current
and the actuator will lose its excitation holding torque. This, however, will allow
you to adjust the load position manually.
•
When the C.OFF input is turned “OFF,” the driver will turn the output current to
“ON” again and the actuator’s excitation holding torque will be restored. The
C.OFF input must be “OFF” when operating the actuator.
Note •
Normally, keep the C.OFF input in the “OFF” state or leave it
disconnected.
•
Turning the C.OFF input to “ON” resets the deviation counter in the
driver.

×10 (Resolution select) input
Selects and switches to 10 times either of the resolution “500: 0.04°/pulse” or “1000:
0.02°/ pulse” that has been selected with the resolution select switch.
For instance, if “1000: 0.02°/pulse” has been selected, this signal can switch
between the 0.02° step rotation and 0.002° step rotation.
Refer to page 40 for the selection of the resolution select switch.
The resolution select switch [1000/500] is based on the motor resolution. The
resolution of the actuator is 18 times the motor resolution. Refer to the table below.
