9.3.1 Motor data identification and automatic speed controller optimization
Description
Two motor identification options, which are based on each other, are available:
● Motor identification with p1910 (standstill measurement)
● Rotating measurement with p1960 (speed controller optimization)
These can be selected more easily via p1900.
● p1900 = 2 selects the motor identification (motor not rotating).
● p1900 = 1 also activates the rotating measurement; setting p1910 = 1 and p1960
depending on the current control type (p1300).
Parameter p1960 is set depending on p1300 as follows:
● p1960 = 1, if p1300 = 20 or 22 (encoderless control)
● p1960 = 2, if p1300 = 21 or 23 (control with encoder)
The measurements parameterized using p1900 are started in the following sequence after
the corresponding drive has been enabled:
● Motor identification at standstill, after the measurement has been completed, the pulses
are inhibited and parameter p1910 is reset to 0.
● Encoder adjustment - after the measurement has been completed, the pulses are
inhibited and parameter p1990 is reset to 0.
● Rotating measurement - after the measurement has been completed, the pulses are
inhibited and parameter p1960 is reset to 0.
● After all of the measurements activated using p1900 have been successfully completed,
p1900 itself is set to 0.
The measurement progress can be monitored using r0047.
Completion of the individual motor data identification runs can be read via parameters r3925
to r3928.
Note
Non-volatile saving
To set the new controller setting permanently, the data must be saved with p0977 or p0971
in a non-volatile memory.
Note
The motor data identification runs only influence the currently valid motor data set (MDS).
