The application with permanent magnetized synchronous motor (PMSM)
When SVC control is used for the control of PMSM, motor parameters auto-tun-
ing function shall be adopted. Two modes of auto-tuning are available, i.e. static
auto-tuning and rotational auto-tuning.
Before running parameter auto-tuning on synchronous motor, make sure to set
both motor type C1.00 and motor nameplate parameters correctly.
Check and make sure the following points before auto-tuning:
● The motor is in standstill and not at high temperature.
● The power rating of the frequency converter is close to that of the motor.
● Set C1.05, C1.07, C1.09, C1.11 based on motor nameplate data.
● Set E0.08, E0.09 according to motor parameters and actual application condi-
tions.
Disconnect the load from the motor shaft for rotational auto-tuning.
Set auto-tuning mode and start motor parameter auto-tuning:
Set the following parameter according to the control mode of the frequency con-
verter and the application situation:
Code
Name Setting range Default Min. Attri.
C1.01 Motor parameter tuning 0...2 0 – Stop
● 0: Inactive
It’s recommended to run static auto-tuning or rotational auto-tuning for
PMSM.
● 1: Static auto-tuning
Static auto-tuning shall be used when the motor load is not removable. It’s
necessary to input inertia value manually in order to achieve the best control
effect.
● 2: Rotational auto-tuning
