Closed-loop thyristor current control
5-52
System- and communication configuring D7-SYS - SIMADYN D
Edition 06.2002
To optimize the current controller, the setpoint of the higher-level speed
controller should be de-coupled using a switch, or the connection should
be deleted.
5.3.2 Entering the characteristic system quantities
The characteristic system quantities have been entered when configuring
the system and have to be checked when commissioning the system.
After the initialization parameter changes have been entered, the
processors should be reset with a restart at the subrack or using the CFC
online function (Target system\operating status - restart).
