Overview:
This document provides an overview of the operation of the Beijer Frequency Inverter P2 when used for open-loop
permanent magnet (PM) motor control. Beijer Frequency Inverter P2 continues the design philosophy of ‘easy to set-
up’ and ‘high levels of performance’ into PM motor applications through simplification of the parameter set and
intelligent and accurate auto-tuning functions.
Applications:
PM motor control is provided as standard on the Beijer Frequency Inverter P2. In order to simplify the user manual
PM motor parameters have been excluded and this application note is provided as the addendum for this function.
The objective of using a PM motor in combination with Beijer Frequency Inverter P2 is to realize the high efficiency
and savings, in combination with smooth and responsive performance, and smaller motor frame sizes, which can be
achieved.
Beijer Frequency Inverter P2 provides open loop PM motor control, there is no facility for operation of PM motors in
closed loop or for any internal positioning functionality.
The Beijer Frequency Inverter P2 PM Control algorithm is suitable for both Surface mounted (SPM) and rotor inbuilt
(IPM) permanent magnet motors. Brushless DC motor control is realizable but it is important to first consult
technical support for additional data and advice.
