Setting range of P11.08:
Enable and define the overload pre-alarm of the
inverter or the motor.
Setting range: 0x0000–0x1132
Ones place:
0: Motor overload/underload pre-alarm, relative
to rated motor current;
1: inverter overload/underload pre-alarm, relative
to rated inverter current.
2: Motor output torque overload/underload
pre-alarm, relative to rated motor torque
Tens place:
0: The inverter continues to work after
over/under-load pre-alarm
1: The inverter continues to work after underload
pre-alarm and stops running after overload fault
2: The inverter continues to work after overload
pre-alarm and stops running after underload fault
3. The inverter stops when over/under-load
occurred.
Hundreds place:
0: Detect all the time
1: Detect during constant running
Thousands place:
0: Overload integral is invalid
1: Overload integral is valid
Setting range of P11.09: P11.11–200% (relative
value determined by ones place of P11.08)
Setting range of P11.10: 0.1–3600.0s
