Meaning
Indicates whether and if so, which method of the quadrant error compensation
(QEC) is active for the axis:
Inactive
•
Neural QEC learning active
•
Conventional QEC active
•
Conventional QEC w. adapt. comp. value act.
•
(conventional QEC with adaptation of the compensation value active)
Neural QEC active
•
Neural QEC w. ad. meas. time val. act.
•
(neural QEC active with adaptation of the measuring time active)
Neural QEC w. ad. dec. time comp. val. act.
•
(neural QEC with adaptation of decay time of compensation value active)
•
Neural QEC w. ad. meas. time + dec. time comp. val. act.
•
(neural QEC active w. adapt. of measuring time and decay time of
compensation value active)
Indicates whether or not the axis has fulfilled the conditions for "Fixed stop
reached" when the "Travel to fixed stop" function is active (IS
DB31, ... DBX62.5):
Normal control
•
("Travel to fixed stop" function not activated)
Fixed stop reached
•
Failed
•
Indicates the value programmed via FXST[x] or SD43510
$SA_FIXED_STOP_TORQUE or the value defined via MD37010
$MA_FIXED_STOP_TORQUE_DEF for the clamping torque for "Travel to fixed
stop".
Unit: % of maximum torque
