Pd.06 Over-voltage at stall

function selection

Range: 0,1【1】

Pd.07 Over-voltage point at

stall

Range:120.0～150.0%(Bus voltage)【140.0%】

0: Disabled (The proposed option, when braking resistor is mounted)

1: Enabled

Note:

◆During deceleration, the motor’s decelerate rate may be lower than that of inverter

because of the load inertia. At this time, the motor will feed the energy back to the

inverter, resulting in the voltage rise on the inverter's DC bus. If no measures taken,

the inverter over voltage fault will happen.

◆If Pd.06 is set to 1 and enabled, during the deceleration, the inverter detects the middle

direct voltage and compares it with the over voltage point at stall defined by Pd.07. If

the middle direct voltage exceeds the stall over-voltage point, the inverter will stop
