Emotron VS10 - Synchronous Motor: Pole Position Identification (PPI)

150 01-6203-01R3, CG Drives & Automation
7.3.6. Synchronous motor: Pole position identification (PPI)
If a permanent-magnet synchronous motor is operated at the inverter, the inverter can be
configured in such a way that a "pole position identification (PLI)" is executed after every
inverter enable.
Preconditions
In 0x2C00 (P300.00) the motor control type "Sensorless control (SL PSM) [3]" is selected.
Details
The pole position is the angle between the motor phase U and the field axis of the rotor.
The "Pole position identification (PPI) without movement" function is available for the
inverter
VS10/30 for identifying the pole position. For details see the following
subchapters.
