13.3.37 Event 85: Excessive jump in reference value
The drive controller is interrupted if:
§ A29 = 0: Inactive for STOBER device controller
or
§ A540 = 0: disable drive, motor is free to rotate for CiA device controller
Response:
§ The power unit is disabled and axis movement is no longer controlled by the drive controller
§ The brakes are no longer controlled by the drive controller and engage in the event of an
inactive release override (F06)
The drive controller is interrupted with a quick stop if:
§ A29 = 1: Active for STOBER device controller
or
§ A540 = 2: slow down on quick stop ramp for CiA device controller
Response:
§ The axis is stopped by a quick stop; meanwhile, the brakes are controlled by the drive
controller and remain released
§ At the end of the quick stop, the power unit is disabled and axis movement is no longer
controlled by the drive controller; the brakes are no longer controlled by the drive controller
and engage in the event of an inactive release override (F06)
Number Cause Check and action
1: Item Fast reference position
change leads to acceleration
that cannot be performed
Check the current reference
acceleration against the maximum
permitted acceleration in the drive
controller (E64, E69) and reduce the
reference value change in the controller
or change the motor type if necessary
2: Velocity Fast reference velocity
change leads to acceleration
that cannot be performed
Check the current reference
acceleration against the maximum
permitted acceleration in the drive
controller (E64, E69) and reduce the
reference value change in the controller
or change the motor type if necessary
