Range
【0】: No error
【1】: Static magnetic alignment fault.
【2】: Without PG option card
【3】: Rotation pole alignment is forced to stop
【4】: Rotation pole alignment is time-out.
【5】: Loop adjustment is time out
【6】: Encoder error
【7】: Other error of motor tuning
【8】: Current abnormity occurs when aligning rotation magneteic pole
【9】: Current abnormity occurs while loop adjustment
【10】:Restart magnetic pole alignment and loop adjustment
(8) Offset angle of magnetic pole and PG origin (22-16)
After the completion of magnetic pole realignment, the compensation amount for the
origin will be stored to this parameter.
Note: it is not recommended users to modify this parameter
(9) PM motor tuning (22-17)
Warning! It may cause personal accident due to sudden start of the motor when
performing motor tuning. Therefore, before performing the magnetic pole
realignment, please firstly confirm the motor’s mechanical load and the surrounding
situation.
Warning! For PM motor tuning, it should be in power-on state. Touching the motor
might result in electric shock. Therefore, before performing the magnetic pole
realignment, please don’t touch the motor.
Warning! In the state of the motor connecting or the brake device braking, do not
tune the PM motor. Otherwise, it will result in bad action of the inverter. When
performing magnetic pole realignment on the motor with load, the motor parameter
improperly calculated might occur. Please disconnect the motor and the load and
confirm that the motor can operates smoothly.
1. Before selecting PM motor tuning, please input motor information (22-00) - (22-06)
and the number of encoder pulse (20-27) according to the motor nameplate.
2. Select 1, 2, or 3 for 22-17, and press ENTER, and then you can enter the PM
motor tuning screen. The operator will display the message of "IPrdy". Press RUN
to start the PM motor tuning, and the operator will display the message of “IPtun ".
If the motor is successfully tuned, the message of "IPEnd " will be display. If the
process of the PM motor tuning is interrupted by pressing STOP, the operator will
display the message of " IPbrd "(PM motor tuning interrupted).
Note: 1. The inverter should be firstly performed with the magnetic pole alignment
before the loop adjustment.
2. If the inverter has been performed with the magnetic pole alignment, you
do not need to do magnetic pole alignment again when the power is
resupplied.
(10) Fault history of PM motor tuning (22-18)
If the PM motor tuning is failed, the message of “IPErr” (PM motor tuning failure) will
be displayed; the error reasons and the troubleshooting can be referred to section
five.
Note: PM motor tuning failure history (22-18) only records the automatic tuning
result of the last time. If the tuning is given up or successful, no error will be
displayed.
