Step 4: Select the second motor self-learning mode to perform it. The second motor self-learning mode is basically
the same as the first motor self-learning mode. For more details, please refer to the above introductions of the first
motor self-learning. The steps are shown in
Table 5-9
:
Table 5-9 Second motor self-learning procedure
Steps
Operational content
DC mode self-learning
1
Set b0-00 and H0-xx correctly.
2
Switch the terminals of the second motor to the output U, V and W of the frequency inverter through contactor or
relay.
3
Connect the inverter power terminals R, S, T to the 3 PH power supply, set the second motor nameplate, etc.
4
Set parameter b0-02 (motor self-learning mode) to 1, select DC mode self-learning and the keyboard will display
tUnd2
.
5
Press the MULT key on the keyboard to start the DC mode self-learning and the keyboard will display
tUn--
.
6
The self-learning will complete after a period of time which depends on the capacity of the inverter. Thereafter the
keyboard will display
tUnEd
and blinks for 5 seconds.
7
Check the parameter b2-08 to confirm whether the data is updated.
Full-mode self-learning
1
Set b0-00 and h0-xx correctly.
2
Remove the mechanical load from the second motor and switch the second motor wiring terminals to the output
terminals U, V and W of the frequency inverter by contactor or relay. Wiring PG if required according to the
