State machine for the identification
The identification is effected according to the following state machine:
[5-155] State machine for the identification run
Cancelling the identification
If the input bStartIdent is reset to FALSE, the active identification is cancelled immediately. Resetting
the input bFollowerEnabled to FALSE also results in the immediate abort.
• The output bBusy is reset to FALSE and the drive is brought to a standstill via quick stop.
• The cause for the abort is shown via status output dnState.
Delay of pulse enable
After activation of the function, the identification does not start immediately, but only after the de-
lay time set in C04847 has elapsed. By this, the magnetic flux of the motor can fully build up first
(only required for asynchronous machines).
• If required, the presetting is to be increased in the case of machines with great rotor time con-
stants.
