Four pole position identification methods can be selected:

● p1980 = 1, voltage pulsing, first harmonic

● p1980 = 4, voltage pulsing, 2-stage

● p1980 = 6, voltage pulsing, 2-stage inverse

● p1980 = 10, DC current impression

4.18 Instructions for commissioning permanent-magnet synchronous motors

This procedure functions for magnetically isotropic motors if adequate iron saturation can

be achieved.

This procedure functions with motors that are magnetically anisotropic. During the

measurement, the motor must be at a standstill. The measurement is carried out the next

time that the pulses are enabled.

Using this type of identification, the motor can emit a significant amount of noise.

This procedure functions for all motors; however, it takes more time than the

measurement selected using p1980 = 4. During the measurement, the motor must be

able to rotate. The measurement is carried out the next time that the pulses are enabled.

For extremely high moments of inertia, the run time can be scaled higher using p1999.

Dangerous motor rotation or motion through measurement

The measurement can electrically trigger a rotation or movement of the motor, by up to

a half rotation.

Do not enter the working area of the motor.
