Description
0: Related to current calibration coefficient
1: Unrelated to current calibration coefficient
P11.09 setting range: P11.11–200% (relative
value determined by the ones place of P11.08)
Setting range of P11.10: 0.01–3600.0s
Underload pre-alarm signal will be outputted if
the output current of the VFD or motor is lower
than underload pre-alarm
(P11.11), and the duration exceeds underload
pre-alarm detection time (P11.12).
Setting range of P11.11: 0–P11.09 (relative
value determined by the ones place of P11.08)
Setting range of P11.12: 0.01–360.00s
Used to set the action of fault output terminals
at undervoltage and fault reset.
0x00–0x11
Ones place:
0: Act at undervoltage
1: Do not act upon an undervoltage fault
Tens place:
0: Act during automatic reset
1: Do not act during the automatic reset period
0.0–50.0%
Used to set the speed deviation detection
value.
Used to set the speed deviation detection time.
If P11.14 is set to a non-zero value, and the
speed deviation is greater than the value of
P11.14, which lasts the time specified by
P11.15, the speed deviation fault dEu is
reported.
Note: Speed deviation protection is invalid
when P11.15=0.0.
