Precautions for Correct Use
However short the acceleration or deceleration time is set, the actual acceleration or decelera-
tion of the motor cannot be shorter than the minimum acceleration or deceleration time that is
determined by the moment of inertia J of the mechanical system and the motor torque. An act
of acceleration or deceleration in a shorter time than the minimum acceleration or deceleration
time may cause an over current or over voltage trip to happen.
