Group 4 – System error A
CPX error group 104 (CPX-MMI: [System error A] )
No. Reset typeError levelMessage
46 Start during active teach command not permitted F1 R
Cause Commissioning mode: Starting a commissioning operation during an active
teaching process (SPOS.TEACH=1) is not permissible
Measure  Do not perform a start while teaching; end teaching first.
47 Start during active positioning command not permitted F1 R
Cause Starting the tracking mode during an active positioning command is not
permissible.
Measure  End the active positioning command and wait for Motion Compete
(SPOS.MC=1).
Cause Rising edge at CPOS.START not permitted during:
– homing
– jogging
– commissioning operation
Measure  Active positioning command must be completed or stopped (SPOS.MC=1).
Cause Rising edge at CPOS.HOME not permitted during:
– homing
– jogging
– commissioning operation
– positioning command
Measure  Active positioning command must be completed or stopped (SPOS.MC=1).
Cause Rising edge at CPOS.JOGN or CPOS.JOGP during active positioning command.
Measure  Active positioning command must be completed or stopped (SPOS.MC=1).

No. Message Error level Reset type
50 Supply pressure is too low W (F2) F
Note Message can be parameterised alternatively as a warning (W) or error (F2).
Cause Pressure in both cylinder chambers is too low or rises too slowly. The response
delay for pressure monitoring can be optimised with FCT or PNU 1144.
Measure  Check compressed air supply.
 Adjust response delay parameter (è FCT or PNU 1144).
51 Controller load voltage outside the tolerance range F2 F
Cause Load voltage < 20 V with enabled drive or overload on axis string.
Measure  Check load supply for valves (U
VAL
).
52 Controller operating voltage outside the tolerance range F2 F
Cause Operating voltage < 18 V or overload on the axis string.
Measure  Operating voltage supply for electronics/sensors (U
EL/SEN
).
