RUNNING THE CONVEYOR
4-1. BE SURE TO GROUND MACHINE BEFORE OPERATION
1. Variable-speed Type (For standard machines, speed is changed by inverter.)
100V single-phase power source
Connectors (male & female) with earth are attached to power cable. Be sure to ground machine by
connecting earth terminal of connector on power source side (female connector).
200V single-phase/three-phase power source
Power cable has ring terminals. When wiring, be sure to make proper earth wiring from earth terminal
of power cable.
2. Constant-speed Type
For standard machines, power source is 200V three-phase only and motor cable (0.3m, with ring
terminals) is provided. When wiring, be sure to make proper earth wiring from earth wire of power
cable. Control unit (switch etc.) is optional.
NOTE: For 100/200V single-phase power source, standard machines are not constant-speed type.
●Power cable and terminals (for inverter variable-speed type)

■Caution When Using Inverter
CAUTION
1. Be sure to confirm that the power source voltage is within the rated voltage
range, before switching ON the power source. (Voltage exceeding the rated
voltage could cause fuming, abnormal noise, etc.)
2. Be sure to start and stop the conveyor with RUN/STOP switch. When starting
and stopping the conveyor frequently in a short period (tact operation etc.), it is
impossible to start/stop the machine by turning on/off the power supply. In this
case be sure to start and stop the machine by external signals. (Inverter
variable-speed type is different from speed controller’s, and the power supply
will trip.) Do not start and stop the conveyor excessively frequently. It may cause
machine failure or shorten its service life.
3. The RUN/STOP switch of inverter unit is not for turning the power on and off.
When leaving the conveyor unused for a long period, make sure that the mains
is off.
4. Do not run the conveyor at excessively low speed for a long period, or start and
stop the conveyor excessively frequently. These may cause machine failure or
shorten its service life.
5. Do not touch the inverter radiator of side of inverter unit, and do not allow any
material to touch it, because of its high temperature.
6. Use the inverter unit within the permissible range of ambient temperature (from
–10℃ to ＋40℃). Avoid freezing.
7. Pay special attention not to allow any foreign matter (dust, iron powder, etc.) to
get into the inverter unit.
8. Operating the motor using the inverter could cause noises from the inverter I/O
cables, motor, etc. Keep in mind that these could interfere with the correct
operation of other electronic devices. (In this case, noises and their effects can
be suppressed to some extent by providing the inverter I/O with a filter or
otherwise shielding the power cable.)

■Belt Tension
Do not take up belt too much, but only to extent that belt does not slip on drive pulley, i.e. enough to drive
belt.
NOTE: 1. Belt occasionally shrinks depending on carried materials or type of belt. In this case make
adjustment by turning take-up bolts counterclockwise.
2. Excessive belt take-up may overload motor or shorten service lives of belt, pulley, etc.

TAKING UP THE BELT
When belt is slackened off, take up belt as follows:
To take up belt, turn right and left take-up bolts(*1) of drive unit clockwise with a spanner. Take-up
pulley(*2) will then be moved and belt will be taken up. When turning take-up bolts(*1), adjust them
alternately, little by little, to keep their movement lengths the same.
If belt is taken up too much, properly adjust the tension by turning take-up bolts(*1) counterclockwise.

2. Positions of Drive Side Plates
Confirm that right and left drive side plates are symmetrically
positioned. → See p. 24.
NOTE: If drive side plates are not positioned equally on right and left sides, it may cause belt deviation. Be
sure to check their positions before using conveyor because side plates may have shifted out of
position in transit.

BELT ALIGNMENT ADJUSTMENT
When belt is not correctly aligned, make adjustments as follows:
6-1. PRIOR CHECKING
1. Frame Condition
Confirm full length of frame is level on top, straight and not bent in any place. →See p. 11.
Drive side plate Measure this length on
both sides to check
installation condition of
right and left drive side
plates.
Correct condition
Dislodgment
Pulley of non-deviation model
3. Dirt on Pulleys
Check drive pulley, head and tail pulleys, etc. for dirt. Remove any dirt and clean. (Remove drive bottom
cover to check.)
4. Loading Condition
Improper loading, i.e. not-centered, may cause belt deviation.
5. Dislodgment of V-form Strip
For non-deviation models(GLV, GLHV model, etc.), check if V-form strip on belt undersurface has
dislodged from V-form belt guidance grooves on pulleys and rollers. (Remove drive bottom cover to
check.)

19
6. Belt Deviation
Check how belt is deviating before adjustment. Correct positions of the following parts while running
conveyor slowly, and then continue running it for a while to check any further belt deviation.
-Take-up devices: Position and adjust them equally on right and left sides.
-Head and tail pulleys: Set at right angle to frame.
6-2. BELT ALIGNMENT ADJUSTMENT
After checking belt deviation, adjust each part following the procedures on p.19-20 while
running conveyor slowly.
NOTE: It is necessary to wait until belt running stabilizes after each adjustment step and to adjust belt
alignment little by little. Belt running will not change immediately.
1. Adjustment Using Take-up Pulley
On side to which belt is deviating, slightly turn take-up bolt(*1) of drive unit counterclockwise with a
spanner. Take-up pulley(*2) will then move outward on this side and belt will center itself.
Alternatively adjust on opposite side. In this case turn take-up bolt(*1) clockwise. Take-up pulley(*2)
will then move inward on this side and belt will center itself.

20
2. Adjustment Using Head or Tail Pulley
On side to which belt is deviating, loosen hexagon socket set screw(*3) and slightly turn adjustment
screw(*4) clockwise. Head (or tail) pulley will then move outward on this side and belt will center itself.
Alternatively, on opposite side, if there is a space between frame end and pulley bracket, make
adjustment on this side. In this case slightly turn adjustment screw(*4) counterclockwise. Head (or tail)
pulley will then move inward on this side and belt will center itself.
Once adjustment is complete, be sure to retighten hexagon socket set screw(*3).
3. Adjustment Using Return Roller (if any return rollers are attached)
On one side, loosen return roller bracket(*5) attachment bolt(*6), and set return roller slightly
diagonally. Belt will then move to form right angle to return roller rotation axis.
NOTE: It is effective to adjust the closest return roller to tail pulley. (The closest return roller to tail
pulley alternates depending on direction of belt travel as shown in figure below.)
