Torque compensatory controller on
Signal(s) updated: Cyclically
Torque compensatory controller is to be activated.
The following conditions must be fulfilled for activation:
DB31, ... DBX96.2 ("fine" differential speed reached)
Torque compensatory controller is to be deactivated.
Master/slave on
Signal(s) updated: Cyclic
Master-slave coupling should be activated.
Master-slave coupling should be deactivated.
The following conditions must be fulfilled for activation and deactivation:
• Leading and following axes under position control (DB31, ... DBX61.5)
• Leading and following axes are at standstill (DB31, ... DBX61.4)
• The channels of the leading and following axes are in the reset state (DB21, ... DBX35.7)
If a condition is not fulfilled, the coupling will not be activated or deactivated. No alarm
appears and the status of the coupling remains the same.
If, at a later point, all conditions are fulfilled, the coupling will be activated or deactivated
depending on the status of the signal.
The signal for the following axis of a coupling is relevant.
Signal(s) updated: Cyclic
