3-2-1-4 Motor Parameter Autotuning
⚫ In parallel model, the master drive must switch back to single unit mode before executing
motor parameter autotuning, Pr.00-62 = 1 (master mode) changes to 0 (single unit mode). Be
aware that the output side wiring of the Slave must be removed (as shown in the following
figure), otherwise there is a risk of the Slave boosting the voltage.
⚫ When driving a permanent magnet synchronous motor, execute the parameter autotuning
according to Pr.05-00 settings.
⚫ When driving an inductance motor and using speed tracking function by the motor vector flux
(Pr.07-12 = 4), set the simple rolling auto-tuning for IM according to Pr.05-00 settings.
⚫ After the autotuning is completed, re-connect the output wiring to the Slave and change the
single unit mode back to master mode (Pr.00-62 = 1).
