(2) Drive Pulse Input（Cw, Ccw - Melec ADB-2F30BA Instruction Manual

(2) Drive pulse input（CW, CCW）
① Operating current range : 9mA～27mA
The photo-coupler turns on with
inter-terminal voltage of 3.1 V～5.5 V.

● Inputting drive pulse causes the current output to the motor to change from
HOLD CURRENT to DRIVE CURRENT, which returns to HOLD CURRENT in about "t1".
DRIVE CURRENT continues if pulse is input on driving-state.
