1-6 Calibration of Home Position
1. Set the cutting length to 100.0mm.
- This is the temporary value for comparing the
set value with the actual cut length.
2. Cut some sheets.
- Do not align the sheets on the side guide. Align the
sheets only on the backgauge properly, and cut.
3. Measure the dimension of cut sheets.
- Measure the dimension of the sheets by one
decimal place. 100.6mm is given for an example here.
4. Obtain the correction value.
- Correction value is a half of the difference
between the set value and the actual cut length.
- The actual cut length is 100.6mm. Therefore,
the correction value is 0.3mm.
5. Enter a new home position. (Fig.2)
- Show the Backgauge Calibration screen.
(Fig.1, Fig2)
- Add or subtract the correction value which was
calculated in step 4 to or from the current home
position value, and enter the new home position
value. (When the actual cut length is larger than
the set value, substract the correction value.)
In the case of the example, enter the value which
is subtracted by 0.3 and press the button.
The backgauge will move to the new home
position.
6. Check.
- Follow the steps 1 through 3 and check that the
set value matches the actual cut length.
7. Rewrite the home position sheet.
- The home position sheet is attached to the
bottom of the control panel box shown in Fig.3.
Rewrite the new home position on it.

Home Position Sensor
Sensor Plate
B21
Servo Motor
M20
Explanation of "Home Positioning"
1. At first, the backgauge moves backward and
B21 home position sensor (Fig.2) detects the
sensor plate and turns on.
2. When B21 turns on, the servo motor M20
rotates in the reverse direction and moves the
backgauge forward, and B21 turns off.
3. The motor stops at the position where Z-phase
from the encoder is detected for the first time
in one rotation of M20. This position is the
home position.
- The encoder is housed in M20.
Explanation of "Motor Home Position
Distance"
- The motor home position distance is the
distance between the position which the B21
home position sensor turns off from on and
the position where the Z-phase from the
encoder is detected for the first time in one
rotation of M20. (steps 2 and 3 above).
- One rotation of M20 servo motor is set to 250
in APC-61II. The position of the home position sensor B21 is set so that Z-phase will be
detected at the middle of the motor rotation.
Therefore, the motor home position distance
should be around 125. (Fig.1)
Checking the Motor Home Position
Distance
- The Z-phase cannot be detected correctly
around the area that the B21 home position
sensor turned off from on, and the boundary
line of the first and second rotation of M20.
If the Z-phase appears at these areas, the
encoder may misread it, and
phase which appears next. This will set the
home position to the wrong position.
Therefore, checking the home position dis-
tance is necessary to make sure the encoder
reads Z-phase correctly in the stable area.

2-1 blinks on the Display (Backgauge Does Not Operate) Part 1
Why does blink on the display ?
Backgauge is traveled by the screw shaft which is driven by motor. Encoder is installed directly at the back end of the screw shaft, and
the operation distance of backgauge is controlled by counting the number of pulse from the encoder. In case that pulse signal does not
come from encoder while the backgauge is moving, blinks on the display inform to the trouble.
Backgauge is at the front limit position.
When backgauge is at the front limit position
(in normal case about 25mm, when support
plate is fixed about 75mm), limit switch is on.
When turning the power switch on this condition, blinks on the display.
After moving the gauge a little backwards with
adjust knob, turn the power switch on again.
Adjust knob remains being pressed
Adjust Knob
Snap Ring
Spring
Bearing Unit
Micro Switch
In normal case, the adjust knob is pressed by
compression spring to the operation side.
Even if you try to move the backgauge forwards or backwards when the adjust knob
remains being pressed for some reasons, motor
does not drive and
blinks on the display
because the machine is in manual mode.
Shaft of knob is difficult to move.
When the knob does not move smoothly
forwards and backwards, check bearing unit.
Lubricate when movement is dull.
Snap ring unfastens.
When snap ring (STW-20) unfastens, fix it
again.
Compression spring is broken.
When compression spring is broken, replace it
with a new one.

Cement resistance is damaged
When switching the motion of the backgauge

LEDs from No.1 to No.6 do not turn on.
When LEDs from No.1 to NO.6 showing
operation of knife, clamp, and backgauge turn
on normally, input signals are OK. If there is
no problem in output motor, SSR may has a
problem. Replace P.C.B.
Backgauge belt is cut.
Low Speed Belt
High Speed Belt
Motor Blacket
High Speed Motor
When belt is cut or overturned, power is not
transmitted and screw shaft does not drive.
Therefore, no pulse rises from encoder.
Replace belt with a new one.
As for high speed belt for S/N 103001 or
above, a new wider belt is used which is hard
to overturn. To attach this wider belt to a
previous machine, gauge base and motor base
also must be replaced.
(In case of order, please notice it.)

blinks on the dis-
play.
Oil on rail and screw shaft is running out.
When oil is running out, lubricate operating
the backgauge for-and backwards to circulate
oil.
There are some foreign objects on rail and
screw shaft.
When there are some foreign objects such as
paper dust, wipe them off and lubricate
enough.
There is problem in encoder.
Encoder is very delicate. When its shaft bends
because of external shock, it does not operate
correctly, even if it is connected with coupling.

There is contact failure or breaking of cable
from encoder.
Check the voltage between terminal 6 and 8 on
the terminal board 1 (refer to page 7-11) while
rotating the adjust knob slowly.
If the voltage changes
while rotating the knob

2-2 Cut Size is Not Equal Part 1
Backgauge position is determined only by
high speed for- and backward buttons.
When backgauge is operated only using the
high speed forward or backward button, the
backgauge can not stop in the correct position
because of overrun. Determine precious position using low speed forward button or forward operation with adjust knob.
Set screw of coupling is loose.

24VDC is not output from power supply.
PW-24
Power Supply PW-24
If output voltage of power supply PW-24 is
too low, the backgauge is delayed moving or

Check whether there is 24VDC output between 1 and 2 . Check whether there is
100VAC input between 4 and 5 . When there
is not 24VDC output in spite of 100VAC
input, replace power supply.

Clutch
When gap of brake or clutch is not in these
ranges, the time lag results in the motion of the
screw shaft. Therefore, defference between
the indicated size on the display and the actual
cut size results.
Adjust it to correct gap.
Or when there is foreign object such as metal
powder on friction surface, remove it with

2-3 Knife Does Not Lower (Clamp Does Not Lower Either) Part 1
Cutting button A and B are not pressed
simultaneously.
For safety, when the timing to press cut buttons A and B differs more than 0.5 second, the
machine judges the abnormal operation and
hydraulic system does not operate. Press them
simultaneously (within 0.5 second).
There is a problem with cutting button A or B.
When each of cuttig button is pressed separately and slowly, it sounds click. When there
is no sound, there is mechanical problem or of
switch itself. Replace the cutting button
switch.
The cable from cutting button switch is connected with the machine under the front table.
Disconnect this connector and check the continuity with a tester. If there is the continuity
with cutting button pressed, it is OK. If there is
no continuity, replace cutting button switch.
When LED L2 and L4 on control board (See
Ò7-4 Control BoardÓ) lights for a moment and
go out again at the moment of pressing cutting
button, knife or clamp does not reach to the
upper limit position. See the next description.
Knife is not at the upper limit position.
The cutting operation does not start when
either knife or clamp is not at the upper limit
position. Check the sensor for upper limit

Grease on clamp rails is not enough to move
the clamp.
Clamp lifts and lowers guided by right and left
rails. However, when there is not enough
grease between clamp and rail, clamp is difficult to move because of metal friction and does
not return to the upper limit position. When the
upper limit position of clamp is not detected,
cutting operation does not start.

When cut buttons are pressed, first clamp lowers. Second, knife lowers to cut . After that, knife stops and does not lift again. (Clamp
does not lift either.) Or when you release your hands from cut buttons, knife lifts again. However, Step does not proceed automatically.
The depth of knife is too short.
[When knife resharpened for many
times is used]
Resharpened and shortened knife should be
lowered to cutting stick by loosening 2 screws
of knife holder according to “6-2 Knife Replacement” of operation manual. However, in
this case, the tip of knife does not reach to the
cutting stick, though 2 screws are lowered to
the lowest position.
In this condition, if cutting operation starts
with all 7 screws tightened, sensor can not
detect the tip of knife. Therefore, knife tries to
continue lowering.
Replace knife to new one and operate again.
Lift the knife with the cutting depth adjust
dial in advance. Otherwise new knife can cut
into the cutting stick.
Knife does not touch cutting stick when
replacing knife.
When replacing knife, loosen 2 screws of the
knife fastened at the lower limit position in
“Knife Replace Mode”, and lower knife until
the end of knife touch cutting stick, and fix
knife again. Otherwise, knife tries to continue
lowering during normal cutting operation,
because knife is not detected by the lower limit
sensor.

After replacing knife, the position of knife
lower limit position sensor is still lower.
Cutting Depth Adjust Dial
When using knife resharpened for many times,
the position of lower limit position sensor must
be adjusted depending on shortened length of
knife. However, if the position of lower limit
position sensor does not change after replacing
knife with a new one and knife lowered, knife
cuts into cutting stick. Therefore, knife is not
detected by sensor and hydraulic system continue operating so that knife continues lowering.
After releasing your hands from cut buttons
and knife lifts, adjust the position of lower

2-12 Knife Is Down before Operation
After finishing operation of the day before and
turning off hydraulic pressure, the oil in
hydraulic circuit return to the tank because of
slight leak of oil from valves. Therefore knife
lowers depending on the amount of leak
through the night. As a result, when turning
on the power on the next day and pressing
hydraulic pressure switch, knife lifts a little to
return to the upper limit position. If knife is
not lower than clamp before turning on hydraulic pressure switch, there is no problem
for safety and operation.
When knife is lower than clamp, a large oil
leak is occurring in hydraulic system.
Remove the cover of the machine and check
hydraulic system by the following procedure.
WARNING
Oil is leaking at hydraulic hose joint.
Touch the joint between hydraulic hose and
each hydraulic parts. If oil clings to your
finger, the connection of joint is not tight. Fix
the parts side by turning the pipe side.
Oil is leaking from hydraulic cylinder.
When oil is leaking from this part pointed by
an arrow, the problem with the cylinder packing can be considered. Replace cylinder or
disassemble the cylinder and replace rod
packing.
When replacing rod packing, replace
also dust wiper.If knife still lowers,
there is problem with interior
packing inside. Replace the whole
cylinder.
C spring to return the knife is cut.
C spring
I Bolt
Hydraulic Cylinder
When C spring is cut or loose, the force to
return the knife to upper limit position weakens and knife lowers even by a slight oil leak.
When spring is cut, replace it.
Turn power switch off before checking
hydraulic system.
2-21
Page 42
2-13 Knife Lower Limit Position Varies
[Cause 1: Oil temperature variation]
When this machine is operated for a long time,
oil temperature rises and viscosity weakens.
Therefore, the speed of hydraulic cylinder
becomes slightly faster.
When knife lowering speed becomes faster,
because lower limit position becomes lower,
lower limit position needs to be rised with the
cutting depth adjust dial. When operation
begins after long break, because oil temperature returns, uncutting occurs.
[Solution]
Because knife lower limit position changes
depending on the oil temperature variation,
adjust with cutting depth adjust dial for each
time. For S/N 103001 or above, because
hydraulic unit is renewed and oil cooler is
equipped as standerd, the temperature variation
does not occur.
The oil suited to ISO VG32 should be used.
[Cause 2: The timing of lower limit position
detection]
The signal is sent with about 10msec cycle in
this machine. Therefore, the time difference at
10m sec maximum between lower limit position detection and CPU exists.
The variation are caused by the knife moving
distance for this time.
But this variation is in allowable range.

which is displayed on the screen of A24 amplifier. Regarding the mechanical troubles, refer to section 3-15 to check if enough grease
is applied to the spindle and the gauge rail. If grease is applied, remove the timing belt for the backgauge section and turn the spindle
manually to find the cause.
If a trouble occurs in servo system, the A24 sends only one signal to the control P.C.B. Check the alarm number "A**" below which is
】
displayed on the screen of the A24 amplifier to specify the cause of the trouble.
【Cause】A24 input voltage drops.
【Solution】Check the customer power source. If it is normal, check if the main power is not turned on within 5 seconds after it is
turned off. If it is OK, remove the con necto rs CN1 and CN2 o f A2 4 an d tu rn of f th e m ai n po w e r fo r m or e than 10 s e co n ds , a nd th e n turn
it on again. If this alarm appears again, replace the A24 amplifier. If the A10 does not appear, check if ground fault does not occur in
the input circuit of A24.
Cause】There is a problem with RAM/ROM in A24.
【
Solution】Disconnect the connectors CN1 and CN2 of A24 and turn off the main power for more than 10 seconds and then turn it
【
on again. If this alarm occurs again, replace the A24 amplifier.
【Cause】The CPU in A24 overdrives.
Solution】Disconnect the connectors CN1 and CN2 of A24 and turn off the main power for more than 10 seconds and then turn it
【
on again. If this alarm appears again, replace the A24 amplifier.
【Cause】There is a problem with EEPROM in A24
【Solution】Disconnect the connectors CN1 and CN2 of A24 and turn off the main power for more than 10 seconds and then turn it
on again. If this alarm appears again, replace the A24 amplifier.
Cause】The amplifier and the servo motor does not match.
【
Solution】Turn off the main power for more than 10 seconds and then turn it on again. If this alarm appears again, replace the M20
【
servo motor.
Cause】There is a problem with CPU in A24 or P.C.B.
【
Solution】Disconnect the connectors CN1 and CN2 of A24 and turn off the main power for more than 10 seconds and then turn it
【
on again. If this alarm appears again, replace the A24 amplifier.
【Cause】There is a problem with the communication between the A24 amplifier and M20 motor.

Caus es and Soluti ons
【
Cause】Regenerative energy causes the main circuit DC voltage or current inside A24 to excess the specified value.
【
Solution】Check if the backgauge is not moved forward or backward in a short period. If it is not moved, check the set value of the
parameter P00 on A24. If it is OK, replace A24.
【Cause】The rotating speed of M20 exceeds the maximum momentary value.
【
Solution】Check the value of parameter P02. If it is OK, turn off the main power for more than 10 seconds and then turn it on again.
If the same alarm still appears, replace M20 servo motor.
【Cause】The current on A24 Amplifier exceeds the maximum limit.
【Solution】Disconnect output side of the wiring on A24. If the same error stil l ap pears, re place A24. If this error d oes not ap pear,
check if output side of the A24 is not short circuit, or ground fault does not occur.
【
Cause】The converter bus voltage becomes over 400 V.
【
Solution】Check if input power voltage is not too high. If it is OK, turn the main power off for more than 10 seconds and turn it on
again. If the same alarm appears again, check the main power circuit. If it is normal, replace A24 amplifier.
【Cause】The input number of command pulse becomes over 250kpps.
【Solution】Che ck i f there i s n o d e vi ce ne a r A 2 4 which gen era te s noi se. If it is OK, turn off the main po wer for m or e th an 1 0 se cond s
and then turn it on again. If the same alarm still appears, replace A24 amplifier.
【
Cause】The input number of command pulse becomes over 250kpps.
【
Solution】Che ck i f there is n o d e vi ce ne a r A 2 4 which gen era te s noi se. If it is OK, turn off the main po wer for m or e th an 1 0 se cond s
and then turn it on again. If the same alarm still appears, replace A24 amplifier.
【Cause】The setting value of the parameter is not proper.
【Solution】The set value of the parameter may be rewritten because of the error on A24. Refer to section 6-8 an d ch eck the set
value s of th e pa r am e te r.
【Cause】Load exceeds the limit of the overload protection value. (300% of overloading for more than 4 seconds, or 200% of
overloading for more than 4 seconds, or locking for more than 0.3 seconds)
【Solution】Check if the backgauge does not hit any obstacles. If it i s OK, check i f large shee ts are n ot push ed o ut by the ba ckgaug e
in a short period of time. If it is OK, check the wiring between A24 and M20. If it is OK, check the set value of the para meter P01 (auto
tuning). If it is OK, turn the main power off for more than 10 seconds and turn it on again. If the same alarm appears ag ain, replace
A24. If the error still occurs, refer to section 3-15 and 3-16 to check the mechanism of the backgauge.
【
Cause】The residual pulse of the deviation counter excesses 50k.
【
Solution】Check if the backgauge does not hit any obstacles. If it is OK, check neither power voltage dropped rapidly nor shortage
of torque occurred. If it is OK, check the wiring between A24 and M20. If it is OK, check the set value of the p arameter P09 (torque limit
value). If it is OK, turn off the main cover for more than 10 seconds and turn it on again. If the same alarm still appears, replace A24
amplifier. If the error still occurs, replace M20 servo motor.
