Possible reason for error
Detected rotational direction deviates from expected
• When using incremental encoders: Channel A and B reversed
• Motor rotation direction reversed compared with calibration setting
→ teach in the limits new (P.210 = 5)
• Too much " slackening " when starting, brake releases too early or too little
torque, possibly adjust boost (P.140 or P.145).
Bad position transmitter protocol
• Fault on the bus of the position transmitter
• No position data available over an extended period
Pre-limit switch fault (light barrier)
• The pre-limit switch for the light barrier remains activated even in the middle
end position or upper end position.
Reference switch position deviates from permissible
range.
During cyclical synchronization
• Reference switch constantly tripped (defective)
• Reference switch trips too far from the selected reference.
• Reference switch trips in the limit switch band
• P270 and P280 are both at the reference switch
Reference switch position deviates from permissible
range.
• Reference switch lies in the limit switch band
• Reference switch is beyond 15% EO
• Reference switch defective
Reference switch not recognized
• The reference switch is not recognized within 20% EO during automatic
synchronization after power-on
• The reference switch is not recognized in the associated end position.
• Breakaway was detected but not fixed
• The automatic lead in after breakaway has failed
• Disturbed environment
• Loop outside the tolerance range
• Disturbed environment
• Loop outside the tolerance range
• Shortcut or intermitted loop connection wirering
• Shortcut or intermitted loop connection wiring
• Service counter has expired
Controller not parametrized
• The min. necessary basic parameters for the controller have not yet been set
→ Activate DIP-switch and put in the asked parameters.
Message from sensor-actor- interface:
An unknown or incompatible device was detected on
the CAN or RS485 bus. The controller is not able to
identify it and assign it to a device class (detector,
light curtain, etc.).
• The serial number of the connected device is not known --> Replace device.
• The software version or protocol version is incompatible --> Update the
control software.
