Tuning data
(Values measured by offline auto tuning are set automatically.)
0 Offline auto tuning is not performed.
1 Offline auto tuning is performed without motor running.96 (Note 2)
101 Offline auto tuning is performed with motor running.
Note: 1. The electronic overcurrent protection characteristics are also selected simultaneously.
2. Select "101" to increase tuning accuracy.

Tuning execution
·
For PU operation, press the [FWD] or [REV] key.
·
For external operation, switch on the run command.
Note: 1. When "101" is set in Pr. 96, guard against hazards because the motor rotates.
2. To force tuning to end
·
Switch on the MRS or RES signal or press the [STOP] key to end.
·
Switch off the tuning start command or make a forced stop.
3. During offline auto tuning, the following I/O signals are only valid:
·
Input signals
STOP, OH, MRS, RT, CS, RES, STF, STR
·
Output signals
RUN, OL, IPF, FM, AM, A, B, C
4. Special caution should be exercised when a sequence has been designed to open the
mechanical brake with the RUN signal.
5. When performing offline auto tuning, switch on the main circuit power (R, S, T) of the inverter
and then enter the run command.
