14.10 Closed-loop drive control
14.10.1 Motor reactor, sine-wave 󹪝lter, and cable resistance
Overview
The following components between the converter and the motor in󹪞uence the closed-loop
control quality of the converter:
• Motor reactors or sine-wave 󹪝lters
• Motor cable with unusually high cable resistance
Description
In the factory setting, for the motor data identi󹪝cation, the converter assumes that neither a
motor reactor nor a sine-wave 󹪝lter are connected at the converter output.
For the motor data identi󹪝cation, the converter assumes a cable resistance = 20% of the
stator resistance of the cold motor.
Correct parameter setting of the components between the converter and the motor improves
the closed-loop control quality of the motor.
Motor data identi󹪝cation is necessary after changing a parameter.
