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
