P5 .1.16
ab
Identification
ID 299
Minimum value:
N.A.
Maximum value:
N.A.
Default value:
0
Options:
0 = Not action.
1 = Identification only stator resistor - does not spin the motor. This can be done with load attached.
2 = Identification with run - motor stator resistor is completed then the motor is run. This must be completed with unloaded motor.
3 = Identification no run - motor is supplied with current and voltage but at zero frequency.
4 = Identification only inertia - identification for the system inertia only.
Description:
This parameter enables the drive to make an motor identification cycle of the motor once complete the drive will adjust tuning
parameters to improve starting torque and open loop vector control performance. Once set and a run command is given, the operation
will be active then set back to 0 when completed. When a run command is issued, the message on the keypad will indicate ”Auto
tuning” is being performed. If there is an issue with the motor identification, a fault message will be displayed.
