PARAMETER SETTING AND OPERATION OF PULSE/ANALOG INPUT
- SV Series User’s Manual -
■ Switching of external input signal direction
Depending on "Forward start (ST1)" /"Reversal start (ST2)" status, the servo motor status changes as follows:
■ Speed command soft start
This allows smoothing the step type speed command input like acceleration/deceleration to some extent.
Acceleration time: the time for motor fromstop status to max. speed
Deceleration time: the time for moto from max. speed to stop status
Actual accelerate (decelerate) time = x VEL_02(VEL_03)
Servo JOG operation/Z-phase search is also enabled.
