6 - 30 CSDJ Plus Servo Drive User's Manual
Servo drive output pulse may not output A, B phase pulse greater than encoder
! pulse per 1 motor rotation externally. In other words, if the pulse of encoder
attached in the motor is 2048PPR, the pulse output to external side from the
Warning
servo drive cannot exceed 2048 pulse per 1 motor rotation.
