3.11.1 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 143.8 is not equal to 0), if there is an angle error greater than 45° (electrical),
Bit 8 of Parameter
Z143.1– is set and the error message
211 Error While Monitoring the Field Angle
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 (Z143.8–) as a function of the speed set value. If the speed is less
than the field angle speed threshold (Z143.8–), the monitoring remains disabled.
Field angle monitoring only functions for the encoder which is set for motor control.
