12.5.2 Actions with enable
Actions which require that the motors be energized before these actions can be
executed:
• B41 Autotune motor
• B42 Optimize current controller
• B43 Winding test
• D96 Reference value generator
Execute
Please note that since parameter values be determined directly during these ac-
tions, you should perform the action A00 save values afterwards so that the val-
ues are stored safe from loss due to power failure.
B41 Autotuning
NOTICE
During this action, the motor shaft will move.
X Make sure that the motor can turn freely during the action!
Using the action B41 the stator resistance (B53) and stator inductance (B52) are
measured on servo motors. On asynchronous motors Leakage factor (B54) and
Magnetic saturation coefficient (B55) are also determined.
During activation, the enable must be inactive. If you have started the action in
B41.0, you must activate the enable. After the action was concluded, you must
deactivate the enable again. You can then read the measured values (B52 to
B55).
During the action, the cycle time is set internally to 32 msec.
Executing actions with enable
1 Change to the device state Ready for switch on.
2 Set the first element of the action to the value 1 (e.g., B40.0 = 1).
3 Enable the motor.
Ö Element 1 indicates the progress of the action (e.g., B40.1 = 33 %).
4 Wait until element 1 indicates the value 100 % (e.g., B40.1 = 100 %).
5 Turn off the enable.
Ö Element 2 indicates the result of the action (e.g., B40.2 = 0:error free).
