NJ/NX-series CPU Unit Motion Control User’s Manual (W507)
The Maximum Velocity is set to 200 based on a calculation for the conditions (maximum speed:
6,000 r/min, reduction ratio: 1/5, ball screw pitch: 10 mm; 6,000 r/min × 1/5 × 10 mm = 12,000
mm/min = 200 mm/s). The default setting of 400,000,000 would exceed the maximum speed of the
motor, so you must change the setting.
Set the start velocity to 0 when you use a servomotor.
If you use a stepper motor, use 10% to 50% of the maximum self-start frequency to prevent loosing the
sync at startup. However, this depends on the load, so refer to the manual for the stepper motor.
If the target velocity is less than or equal to the start velocity, acceleration/deceleration are not per-
formed and the axis moves at the target velocity.
