７．Grow Time Trimmer
Trimmer to adjust the duration of time in which the motor’s rpm changes from the stationary state to
the rpm set for High Speed and then to the rpm set for the Low Speed.
Adjustable range: 20msec. to 3sec. (When SPEED voltage is changed from 0 to 5Vdc or from 5 to
0Vdc.)

８．Terminals
8-1 STOP/START (Input)
Turning STOP/START input to Low level (connecting to GND potential) will make the motor start to
run and the driver outputs CLOCK OUT signal to motor.
Turning STOP/START input to High level (open) will make the motor stop and the driver stops to
output CLOCK OUT signal.
8-2 CW/CCW (Input)
Turning CW/CCW to Low level (connecting to GND potential) will make the motor rotate in CCW
direction.
Turning CW/CCW to High level (open) will make the motor rotate in CW direction.
Fig.9 Direction of Rotation
8-3 SPEED (Input)
This input is used for changing speed. A voltage input between 0 to 5Vdc would change the speed
from low speed to high speed. The input is maintained at 5Vdc with a 4.7kΩ pull-up resistor.
8-4 GND
Use GND along with SPEED input for remote speed control. As a good practice, use a shielded
wire. Refer to Fig. 10
