Description
This parameter is used to set the proportional
coefficient of the active current regulator during
overvoltage stall.
Setting range: 0–1000
This parameter is used to set the integral
coefficient of the active current regulator during
overvoltage stall.
Setting range: 0–2000
0: Disable
1: Enable
When this parameter is set to 0, the overload
timing value is reset to zero after the VFD is
stopped. In this case, the determination of VFD
overload takes more time, and therefore the
effective protection over the VFD is weakened.
When this parameter is set to 1, the overload
timing value is not reset, and the overload
timing value is accumulative. In this case, the
determination of VFD overload takes less time,
and therefore the protection over the VFD can
be performed more quickly.

Note: The SPO detection is started only after
the VFD runs for the delay time P11.28 to avoid
false alarms caused by the unstable frequency.
