Caution
!
The pulse output circuitry of the Position Control Unit is provided with two types
of terminals: terminals with 1.6 kΩ (1/2 W) resistance and terminals with no re-
sistance. Select the terminals in accordance with the power requirements and
the specifications of the motor driver to be used.

Note Connect between 7 mA and 30 mA loads to the outputs of the Position Control
Unit, or add bypass resistance for loads less than 7 mA.
The diagrams on the following pages illustrate examples of connections to mo-
tor drivers. Always confirm motor driver specifications before making connec-
tions.
In this example, a 5-V photocoupler input motor driver is used for outputting CW
and CCW pulses.

Note In this example, the 1.6 kΩ resistors of the Position Control Unit are used to allow
a 24-VDC power supply to be used with a motor driver rated at 5 VDC.
When wiring your system, carefully note the current required by the motor driver.
Beware of the danger of electric shock from the motor driver.
