■ 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:
NOTE: For pre-assembled machines of 3m or less in length, belt tension is already adjusted. However,check the belt condition before use and make adjustments if necessary.

5-1. USING TAIL TAKE-UP UNIT
Applied to Head Drive Type (including Motor Pulley Model) andOn both sides of conveyor, loosen tail pulley bracket(*1) attachment bolts(*2). Loosen fixing nuts(*4) witha hexagonal wrench, and turn right and left take-up bolts(*3) clockwise with a spanner. Tail pulley andbrackets(*1) will then move outward and belt will be taken up. When turning take-up bolts(*3), adjust
them alternately, little by little, to keep their movement lengths the same. Once adjustment is completed,retighten fixing nuts(*4) and attachment bolts(*2).
