7.1.12 Motor data identification
Description
Motor data identification (MotID) provides a means of determining motor data (of third-party
motors, for example). The drive system must have been commissioned for the first time as
basis for using MotID. To do this, either the electrical motor data (motor data sheet) or the
rating plate data must be entered and the calculation of the motor/control parameters
(p0340) must have been completed.
Commissioning involves the following steps:
● Enter the motor data or the rating plate data and the encoder data
● Complete calculation of the motor and control data as starting value for the MotID (p0340
= 3, if motor data, p0340 = 1, if rating plate data were entered)
● Carry out a static measurement (p1910)
