Note: 1. The electronic overcurrent protection characteristics are also selected simultaneously.
2. Select "101" to increase tuning accuracy.
(2) Tuning execution
• For PU operation, press the
• 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
• 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 executing offline auto tuning, give the run command after switching on the main circuit
power supply (R, S, T) of the inverter.
Set the rated motor current (A).
