J PULSE OUTPUT FUNCTION
The CPM1A transistor output models have an output function
capable of outputting a pulse of 20 Hz to 2 kHz (single-phase
output).
When used in combination with a Stepping Driver or SmartStep
Servodriver, positioning can be easily performed.
Application Example
Changing the speed of the Stepping Motor.
