7.1.10 Optimizing the current and speed controller
General information
CAUTION
Controller optimization may only be performed by skilled personnel with a knowledge of
control engineering.
The following tools are available for optimizing the controllers:
● "Function generator" in STARTER
● "Trace" in STARTER
● "Measuring function" in STARTER
● Measuring sockets on the Control Unit
Optimizing the current controller
The current controller is initialized when the system is commissioned for the first time and is
adequately optimized for most applications.
