■ Caution When Using Inverter

CAUTION16

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 startingand 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 thiscase 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 andstop 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 canbe suppressed to some extent by providing the inverter I/O with a filter orotherwise shielding the power cable.)5

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 themalternately, 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.

■ 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 makeadjustment by turning take-up bolts counterclockwise.
2. Excessive belt take-up may overload motor or shorten service lives of belt, pulley, etc.

1. Frame Condition
Confirm full length of frame is level on top, straight and not bent in any place. → See p. 11.

Bent

Not level

Lopsided

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.

Drive side plate
Measure this length on
both sides to checkinstallation condition ofright and left drive sideplates.
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 tocheck.)
