1500 1500  In the speed control mode, excessive acceleration of the speed instruction will cause the motor to jump or vibrate. Therefore, a suitable acceleration and deceleration time can realize the smooth speed change of the motor and avoid the occurrence of mechanical damage caused by the above situation.
