Input signals

The following input signals of the driver are photocoupler inputs. The signal state represents the "ON: Carrying
current" or "OFF: Not carrying current" state of the internal photocoupler rather than the voltage level of the signal.
 CW [PLS] input, CCW [DIR] input
These signals are used when the motor is operated by inputting pulses.
These inputs serve as the CW and CCW inputs in the 2-pulse input mode, or PLS and DIR inputs in the 1-pulse input
mode. Set the pulse input mode of the driver according to the pulse output mode of the controller (pulse generator)
used with the driver. When inputting the pulse, check the PLS-RDY output is turned ON.
PLS-RDY output
Pulse input
When the motor is at standstill, be sure to keep the photocoupler in OFF state.
 Maximum input pulse frequency
 When the controller is of line driver type: 1 MHz (duty cycle is 50%)
 When the controller is of open-collector type: 250 kHz (duty cycle is 50%)
 2-pulse input mode
When the CW input is turned from OFF to ON, the motor will
rotate by one step in CW direction.
When the CCW input is turned from OFF to ON, the motor will
rotate by one step in CCW direction.
Do not input the CW signal and CCW signal simultaneously. If the other signal is input while one of
the signals is ON, the motor cannot operate normally.
 1-pulse input mode
When the PLS input is turned from OFF to ON while the DIR
input is ON, the motor will rotate by one step in CW direction.
When the PLS input is turned from OFF to ON while the DIR
input is OFF, the motor will rotate by one step in CCW direction.
 START input
This signal is used to start positioning operation. It is not used when the motor is operated by inputting pulses.
Select the operation data number and turn the START input ON to start positioning operation.
