Short Description Number of Motor Poles


The number of motor poles per turn of the motor.
MPOLES = 0 is not saved into the drive. The setting MPOLES =0 is also not monitored in the MMI.

Linear Motors:
The standard setting for linear motors is MPOLES = 2.
An exception is if enclines is not an integer value for the pole pitch distance (MPITCH). In this case a differnt value for enclines and MPOLES is required. Contact our technical support.

In all sensorless modes (FBTYPE = 10.11), the output frequency is limited to 599 Hz. This yields the following limits of maximum speed (in RPM): MSPEED (max) = 599Hz * 60 / (MPOLES/2) If your application requires a higher output frequency, please contact our support.

Under certain conditions, this variable is to be seen as a configuration variable. Only the setting of the value to 0 can be done with enabled power stage. All other changes may only be made if the power stage is disabled.

With these parameters, the amplifier decides whether a COLDSTART is necessary. The MPOLES change from the last value after the COLDSTART to 0 or back to 0 does not require a COLDSTART, otherwise a COLDSTART is required (e. g. from 6 to 8).
