At a Glance
These faults are signaled by the bit HD_ERR (%Ir.m.c.4). These faults are blocking faults and cannot be deactivated.
Emergency stop
The following table shows the cause, the signal and the remedy to be applied in the case of a Emergency stop fault:
Cause
Circuit open between the 24V and the Emergency stop input on the front panel of the module
Parameters
None
Consequence
The moving part is forced to stop
Signal
EMG_STOP (%Ir.m.c.29) and EMG_STP (%MWr.m.c.3.5) bits
Remedy
Re-establish the connection between the input and the 24V then acknowledge the fault.
24V supply
The following table shows the cause, the signal and the remedy to be applied in the case of a 24V supply fault:
Cause
24V supply fault
Parameters
None
Consequence
The axis is not referenced, the moving part is forced to stop
Signal
AUX_SUP bit (%MWr.m.c.3.6)
Remedy
Re-establish the connection then acknowledge the fault
Brake output short circuit
The following table shows the cause, signal and the remedy to be applied in the case of a Brake output short circuit fault:
Cause
Short circuit detected on the module’s brake output
Parameters
None
Consequence
The axis is not referenced, the moving part is forced to stop
Signal
BRAKE_FLT bit (%MWr.m.c.3.1)
Remedy
Remove the short circuit then acknowledge the fault
Translator
The following table shows the cause, the signal and the remedy to be applied in the case of a Translator fault:
Cause
The translator check input does not receive the level translator OK defined in the channel configuration
Parameters
None
Consequence
The axis is not referenced, the moving part is forced to stop
Signal
DRV_FLT bit (%MWr.m.c.3.2)
Remedy
Remove the translator fault then acknowledge the fault
