GD-5510-01
Instructions 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.
(Photo-coupler diode V
F
≒ 1.6 V)
② Timing chart
[To the line driver 26LS31]
t1≧0.5μs, t2≧0.5μs, tf,tr≦1μs
t3>1μs,
t4>1μs
Maximum response frequency : 1MHz
● The shaded area ( ) indicates light emission from the photo-coupler,
and the motor is driven at the rising edge ( ).
"t4" greatly varies according to the inertial moment including that of the motor.
③ Automatic switching for DRIVE/HOLD

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