・Note that the unit cannot be operated at maximum speed if the step division is high due to maximum response frequency limits.
■ Timing chart
◆ 2-input type
Counted at the edge of pulse drop
CW pulse
CCW pulse
Direction of motor operation
CW rotation
10 μs or greater
CCW rotation
・■ indicates that the photocoupler is ON.
・CW rotation means rotation in a clockwise direction when viewed from the motor flange side; and CCW rotation means rotation in a
counterclockwise direction when viewed from the motor flange side.
・Do not input CW/CCW pulses at the same time.
・The CW/CCW pulse switching time of“10 μs or greater”is the operating time for the driver internal circuit, not the motor response time.
Set a time in which the motor can respond for actual operations.
・1-input type and 2-input type can be switched by setting the DIP switch: F/R.
