4.11 Monitoring

4.11.1 Field angle monitoring

Field Angle Monitoring on Synchronous Machines
The controller determines the pole wheel direction of the rotor with the aid of the motor
model. This is then compared with the pole wheel direction which is calculated from the
encoder used for motor control. When the monitoring is enabled (i.e. the monitoring
threshold
Bit 8 of Parameter
is initiated. The pulse enable is blocked as a result.
The cycle time of the monitoring part for error triggering is 1 ms.
Additionally, the field angle monitoring can be switched on and off by setting the field an-
gle speed threshold (143.8) as a function of the speed set value. If the speed is less than
the field angle speed threshold (143.8), the monitoring remains disabled.
Field angle monitoring only functions for the encoder which is set for motor control.
