4.15 Instructions for commissioning permanent-magnet synchronous motors

● Motor identification (standstill (static) measurement (p1910)
● Rotating measurement (p1960)
The following parameters can be entered in STARTER during the commissioning phase:
The optional motor data can be entered if it is known. Otherwise, they are estimated using
the rating plate data or are determined using a motor identification routine or speed controller
optimization.

Permanent-magnet synchronous motors, rotating
Permanent-magnet synchronous motors with or without encoder are supported.
The following encoder types are supported:
● Encoder with position information (e.g. without CD track or reference signal)
● Encoder without position information
For operation without encoders or with encoders without position information, a pole position
identification must be carried out (see the chapter on pole position identification for further
details).
Typical applications include direct drives with torque motors, which are characterized by high
torque at low speeds. When these drives are used, gear units and mechanical parts subject
to wear can be dispensed with if the application allows this.
