Note: The electronic thermal relay function characteristics are also selected
simultaneously. By setting any of "100 to 123", the electronic thermal relay
function changes to the thermal characteristic of the constant-torque motor
when the RT signal switches on.
(2) Tuning execution
• For PU operation or combined operation 2, press the
• For external operation or combined operation 1, switch on the run command.
Note: 1. To force tuning to end
• Switch on the MRS or RES signal or press the
• Switch off the tuning start command to make a forced end.
2. During offline auto tuning, only the following I/O signals are valid:
• Input signals
<Valid signals>
MRS, RES, STF, STR
• Output signals
RUN, FM, A, B, C
3. Special caution should be exercised when a sequence has been designed to
open the mechanical brake with the RUN signal.
Set the rated motor current (A).
