4.12 Motor data identification and rotating measurement
Description
Two motor identification options, which are based on each other, are available:
● Motor identification with p1910 (standstill measurement)
● Rotating measurement with p1960
Note
For both types of motor identification the following applies:
If there is a motor brake, then this must be open (p1215 = 2).
These can be selected more easily via p1900. p1900 = 2 selects the standstill measurement
(motor not rotating). The setting p1900 = 1 also activates the rotating measurement, i.e. with
the setting of p1900 = 1 and p1960 depending on the current control mode (p1300).
