Description
0x0000–0x1134
Ones place:
0: Motor OL/UL pre-alarm, relative to the motor
rated current.
1: VFD OL/UL pre-alarm, relative to rated VFD
output current.
2: Motor output torque OL/UL pre-alarm,
relative to motor rated torque.
3: Motor OL/UL pre-alarm. The overload is
relative to the motor rated current; while the
underload is relative to the motor rated power.
4: VFD OL/UL pre-alarm. The overload is
relative to the VFD rated current; while the
underload is relative to the VFD rated power.
Tens place:
0: The VFD continues to work for an OL/UL
alarm
1: The VFD continues to work for a UL alarm
but stops running for an OL fault.
2: The VFD continues to work for an OL alarm
but stops running for a UL fault.
3: The VFD stops running for an OL/UL alarm.
Hundreds place:
0: Detect all the time.
1: Detect during constant speed running
Thousands place:
reference selection
0: Related to current calibration coefficient
1: Irrelated to current calibration coefficient
If the VFD or motor output current is larger than
the overload pre-alarm detection level (P11.09),
and the duration
pre-alarm detection time (P11.10), overload
pre-alarm signal will be outputted.
