LOGIC CONNECTOR ASSIGNMENTS
Terminals 7, 8 and 9 are opto-isolator LED anode inputs in series with 200 Ohm current limit resistors. The LED cathodes go to
the COMMON terminal. The inputs work with 2.5V, 3.3V and 5V logic levels. Minimum logic 1 input current is 2 mA. Terminals 5,
6 and 7 are three opto-isolated collector outputs that have a 10 mA current sink rating and their emitters go to the COMMON
terminal.

TERMINAL 7: RUN/STOP
This input is the only way to control VCO mode on or off. Ap5VDC to TERMINAL 7 will cause the motor to accelerate to
the speed set at the CW and CCW trimpots. Re5V will cause the motor to decelerate to a stop.
TERMINAL 8: CW RUN
This input is a CW RUN input. Ap5V to this input will accelerate and run the motor to the speed set on TRIM4.
TERMINAL 9: CCW RUN
This input is a CCW RUN input. Ap5V to this input will accelerate and run the motor to the speed set on TRIM5.
TERMINAL 10: COMMON
This terminal serves as the COMMON shared GND for the RUN/STOP, CW RUN, and CCW RUN +5V inputs.
TERMINAL 11: MOTOR STOPPED
This open-collector output will go to a logic “0” when the motor is stopped. The time between signaling the motor to stop and
this output going low will be equal to the deceleration time. This output will only go low when the motor is no longer moving.
