P92.27
Anti-snag indicates that the VFD outputs reserve
torque so that the motor can stop at the fastest
speed. A smaller value of
faster braking speed. When the motor
decelerates to P92.29, the VFD stops.
P92.27 setting range: 0.0–300.0% (of the motor
rated current)
P92.28 setting range: 0.000–10.000s
P92.29 setting range: 0.00–30.00Hz
0–1
0: Disable
1: Enable
After the function is enabled, if the brake is
opened, detection protection is performed.
When the set frequency is equal to or lower than
the value of P92.31, a fault is reported (the
frequency setting fault SFE is reported after the
speed is decreased if the speed is high); if the
brake is closed, no detection is performed.
0.00–10.00Hz
0.0–5.5
When the value is not zero, current imbalance
detection is enabled. When the 3PH current
max. value divided by the min. value is greater
than this multiple, the Cuu fault is reported.
