Note:
◆
During deceleration, the motor’s decelerate rate may be lower than that of ac drive
because of the load inertia. At this time, the motor will feed the energy back to the ac
drive, resulting in the voltage rise on the ac drive's DC bus. If no measures taken, the
ac drive over voltage fault will happen.
◆
If Pd.06 is set to 1 and enabled, during the deceleration, the ac drive detects the middle
direct voltage and compares it with the over voltage point at stall defined by Pd.07. If
