Description of change

Automatic calculation of the P and I

factor of the current controller is

now possible for synchronous and

asynchronous motors. However,

automatic calculation is not to be

used for linear synchronous and

torque motors. The calculated value

is entered in the configuration. An

asterisk (*) is prefixed to the

parameters to identify the

automatically calculated value, see

the machine configuration. It is no

longer necessary, because the

value is now read from the power

supply module table SUPPLY.SPY.

Defines the setting for field

weakening for synchronous motors.

The parameter was revised to

provide new modes for field

weakening. For the chapter dealing

with information on weakened-field

operation, please refer to
