Carrying out the rotating measurement (p1960 > 0)
The following measurements are carried out when the enable signals are set and a switch-
on command is issued in accordance with the settings in p1959 and p1960.
● Encoder test
If a speed encoder is used, the direction of rotation and the pulse number are checked.
● Only for induction motors:
– Measurement of the magnetization characteristic (p0362 to p0369)
– Measurement of the magnetization current (p0320) and determination of the offset
– Measurement of the saturation of the leakage inductance and setting of the current
● Speed controller optimization
– p1470 and p1472, when p1960 = 1 (operation without encoder)
– p1460 and p1462, when p1960 = 2 (operation with encoder)
– Kp adaptation switch-off
● Acceleration pre-control setting (p1496)
● Setting for ratio between the total moment of inertia and that of the motor (p0342)
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.
Danger to life if the motor unexpectedly moves during motor identification in the rotating
mode
When selecting motor identification with optimization in the rotating mode, after
commissioning, the drive initiates that the motor rotates with speeds that can reach the
maximum motor speed.
• Observe the general safety instructions.
• Ensure that the EMERGENCY STOP functions are fully functional when commissioning
Note
Speed controller optimization for operation with encoder
If speed controller optimization is carried out for operation with an encoder, the control mode
will be temporarily changed over to encoderless speed control automatically, in order to be
able to carry out the encoder test.
