Motor identification and automatic speed controller optimization

Description
Two motor identification options, which are based on each other, are available:
● Standstill measurement with p1910 (motor identification)
● Rotating measurement with p1960 (speed controller optimization)
These can be selected more easily via p1900. p1900 = 2 selects the standstill measurement
(motor not rotating). p1900 = 1 also activates the rotating measurement; p1900 = 1 sets
p1910 = 1 and p1960 in accordance with the current control type (p1300).
Parameter p1960 is set depending on p1300:
● 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:
● Standstill (static) measurement - after the measurement has been completed, the pulses
● Encoder adjustment - after the measurement has been completed, the pulses are
● Rotating measurement - after the measurement has been completed, the pulses are
● After all of the measurements activated using p1900 have been successfully completed,
Note
To set the new controller setting permanently, the data must be saved with p0977 or
p0971 on the non-volatile CompactFlash card.

are inhibited and parameter p1910 is reset to 0.
inhibited and parameter p1990 is reset to 0.
inhibited and parameter p1960 is reset to 0.
p1900 itself is set to 0.
DANGER
During motor identification, the drive might set the motor in motion.
The EMERGENCY STOP functions must be fully operational during commissioning. To
protect the machines and personnel, the relevant safety regulations must be observed.
