Error Messages
Upon detection of an error, the cutting roll remains in a closed-loop standstill at home position
after termination of the current cut. Output “Error” switches to high and the unit displays a
flashing error message “Error…” indicating the error number.
To clear an error state either set “Clear Error” command or cycle the power supply of the unit.
Please note that the unit will immediately return to the error state if the cause for the error has
not been eliminated.
Error No.
Error Description
Error 0
The reason for the error has been rectified (e. g. parameter value amended after
Value Range Error) but the error has not yet been cleared by input “Clear Error”.
Error 1
Cut not possible:
The cut is not possible because the preset cutting length is too low.
Error 2
No Cutting Pulse:
The cutting pulse is missing.
This error will be set if no cutting pulse appears within one revolution of the
cutting roll.
Error 3
Power Low:
The power supply voltage is too low.
This error cannot be cleared before the power supply voltage has recovered and
exceeds the minimum power supply voltage level.
Error 4
Val. Range exceed:
Internal overflow error during pre-calculation of the cutting profile.
This error can occur by the following reasons among others:
The ratio between the number of line encoder pulses and the number of
cutting roll encoder pulses has exceeded the permitted range (see section
4.2 “system configuration” for details).
The value of “Home switchpoint” is too high.
The synchronous zone (sum of “Sync. Before Cut” and “Sync. After Cut”) is
greater than the cutting roll circumference
