Tips: How to set VFD acceleration and deceleration time?

RCF of VFD in starting and braking process is set by user. If the moment of inertia J and load of the motor increase or decelerate at a predetermined frequency, the acceleration torque may not be sufficient, thus resulting in the motor stall. Namely the motor speed is not in harmony with the output frequency of VFD, thus causing over-current or over-voltage. Therefore, the acceleration and deceleration time shall be set reasonably according to the moment of inertia and load of the motor, so that the RFC of VFD can be coordinated with the speed change rate of the motor.

The method to check whether this setting is reasonable is to select the acceleration and deceleration time according to experience. If over-current occurs during start-up, the acceleration time can be prolonged appropriately; In case the over-current occurs during braking process, the deceleration time shall be prolonged appropriately. In the other hand, the acceleration and deceleration time shall not be set too long, otherwise the production efficiency would be affected, particularly the frequent starting and braking.
