13.3.16 Event 47: Torque limit
The possible effects depend on the configured level (U20):
§
0: Inactive
§
1: Message
§
2: Warning
§
3: Fault
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)
Cause
Check and action
Incorrectly selected torque/force
limits
Check the general machine limit and adjust it if necessary (C03,
C05); check the application limits and the parameters dependent
on the operating mode and adjust them if necessary (STOBER
C132, C133 or CiA 402 A559)
Wrong motor design
Check the design and change the motor type if necessary
Mechanical block
Check the output and correct the block if necessary
Holding brake closed
Check the connection, supply voltage and parameterization and
correct them if necessary (F00)
Connection error at the motor
Check the connection and correct it if necessary
Connection error at the encoder
Check the connection and correct it if necessary
Wrong encoder measurement
direction
Compare the attachment and measurement direction of the
encoder with the corresponding values of the H parameters and
correct them if necessary
