A400 Automatic drive check and adjustment
Diagnosis A400 is a group diagnosis for various system states. It is used
in drive checks and adjustments. A through diagnosis is automatically run
when the drive enable is switched on and off.
Drive checks and adjustments include systems states that are run
through independent on parametrization.
•
sequence of holding brake delay time (see P-0-0526, Brake control
delay)
•
structure of air gap field (is asynchronous motor)
•
automatic determination of commutation offset (if synchronous motor
with incremental measuring system)
Depending on parametrization, the following system status is checked.
•
Automatic brake monitor (see P-0-0538, Motor function
parameter 1)
A401 Drive deceleration to standstill
The drive
•
is brought to standstill as defined in parameter P-0-0119, Best
possible deceleration or
•
carries out "velocity command value equals zero" after a travel range
error has occurred.
