Setting range of P11.10: 0.1–3600.0s
P11.11
Underload
pre-alarm
detection level
Underload pre-alarm signal will be outputted if the
output current of the inverter or motor is lower than
underload pre-alarm detection level (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)
