Run Current*5 50%~150% (Selectable by parameter) RUN current is current value which flows onto the motor during operation (rotation) of the motor and it is set based on arted current of the motor.    * Default: 100%
STOP Current 20%~100% (Selectable by parameter) When motor stop operation, 0.1 second after motor current will be set to STOP current value. STOP current value is a percentage of the rated current of motor.    * Default: 50%
Pulse Input Method 1 Pulse / 2 Pulse (Selectable by DIP Switch)     * Default: 2 Pulse
Rotational Direction CW/CCW (Selectable by DIP Switch)     * Default: CW
Speed/Position Control Command Pulse Train Input
I/O Signal*3 Input Signal Position Command Pulse, Enable, Alarm Reset (Photocoupler Input)
Output Signal In-Position, Alarm (Photocoupler Output), Brake
  • * 1 : Up to the resolution of 10,000[ppr], maximum speed can be reached by 3,000[rpm] and with the resolution more than 10,000[ppr], maximum speed shall be reduced accordingly.
