701
Error Text: WRONG BACKGAUGE DIRECTION !
State: ERROR
Cause: The counting pulses expected from the positioning counter are checked for their
plausibility depending upon their direction of rotation. As a consequence, the value
must be decreased with an advance movement of the backgauge and increased
with the reverse movement. If this is not the case the backgauge run is interrupted
and an error message output. This may be caused by a frequency converter or
pulse generator improperly connected. This monitoring function is also active in
secondary operation.
Remedy: - Check connection of backgauge motor to frequency converter
- Check connection from encoder
- Replace pulse transducer
- Replace board SAP
654
Error Text: NO POSITION COUNTER IMPULSES
State: ERROR
Cause: During an active backgauge run: if no or too few counting pulses are received from
the signal transducer the above error message will be output.
This is done whenever the actual speed of the backgauge falls below the nominal
speed by 1/8.
Remedy: - Check setting of frequency converter (service documentation)
- Mechanical stiffness of backgauge drive
- Check / adjust backgauge drive motor with brake
- Frequency converter is defective
- Check / replace pulse generator
- Check cable routes / connections
- Check / replace board SAP
- Check / replace board CPxx
- Check proper connection of main terminals from backgauge motor
- Parting of cable to the limit switches in the clamp (S6, S218, S218b)
- Check fuse F8
- Current limitation G3 is active (POLAR 66)
- Check correct adjustment of S13 and switching cam
- Check correct grounding of backgauge motor
- Install supporting rings for spindle (Polar 66)
- Check tight fit of spindle extension
- Adjust 0V by means of potentiometer on board SAP.

Error Text: KNIFE IMPULSES MISSING
State: ERROR
Cause: Too few counting pulses have been registered by the computer during an active
cut. The sum of the counting pulses determined is bigger than 275 (knife pulse
trace).
Remedy: - Check correct grounding of frequency converter
- Knife upstroke control is defective
- Check cable route or bus connection / knife upstroke control - SAP - CPxx
- Check / replace boards SAP, CPxx
- Check data of knife gear control or knife trace; wrong pulse values in the trace
are represented inversely
- Check mechanical play of gears
- Knife speed too low (clutch slides, clutch pressure too low).
- Wear of clutch and brake linings.
- Gear is too tight (replace it)
- Check wear or soiling of slip ring and carbon brushes
- Replace magnetic valve Y33
- Short circuit of left bulb of optical cutting line indicator ( model 115)
- Check card SK95, replace, if necessary
- Check solenoid and sensors of safety bolt
- Update the software (V 1.4.5-13 or higher)
- Check air gap of brake on gearbox.
- Check tight fit of shear bolt.

Error Text: SIZE ERROR
State: HINT
Cause: The value determined and filed for the table end size during the reference run is
exceeded by a positioning input. Size inputs smaller than the accurancy allowance
adjusted (default = 0.008 cm) or negative values will cause the same error
message.
Remedy: - Check size input and correct, if necessary
- Check position of table limit switch "at rear" and correct, if necessary, if a size
admissible for the respective machine size cannot be approached.
