■ Caution When Using inverter
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. If installing a separate
RUN/STOP switch and operating the machine by external control, be sure to use thecontrol circuit terminal on the rear of controller unit. (For reversible operation, set thereverse switch to CCW.)
3. The RUN/STOP switch of control unit is not for turning the power on and off. Whenleaving 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 theconveyor excessively frequently. These may cause machine failure or shorten its servicelife.
5. Do not touch the inverter radiator of side of control unit, and do not allow any material
to touch it, because of its high temperature.
6. Use the control 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 control 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 otherelectronic devices. (In this case, noises and their effects can be suppressed to someextent by providing the inverter I/O with a filter or otherwise shielding the power cable.)
For details, refer to “Inverter instruction manual”, appendix.

5. Loosen fixing bolts(*16) and slide catch-clip hooks(*15) to intended position of drive unit, along frameslots. (For fixed drive unit (optional), fixing bolts have been already removed in step 1 above.) Position
all the catch-clip hooks(*15) approximately equally on both sides and temporarily fix them.
NOTE: When sliding catch-clip hooks(*15), loosen fixing bolts of the following parts and slide them
together.
-FTF model: Stopper plates(*18)-FTL model: Side plate liner brackets(*19) with stopper plates(*18) attached
6. Move drive unit and support stand(*7) to intended position. Gently put frame on drive unit and makeadjustments so that drive wheels(*17) will be positioned between 2 pressure rollers(*13).
7. Correctly position catch-clip hooks(*15) and the following parts, according to type of drive unit.
-Easy removable drive unit (standard): Catch-clips(*2)-Fixed drive unit (optional): Drive unit fixing brackets(*2’)
Fix catch-clip hooks(*15) to frame by tightening fixing bolts(*16). Particularly, for easy removable
drive unit, to correctly fit catch-clip hooks(*15) to catch-clips(*2), be sure to fasten catch-clips(*2) tohooks(*15) before tightening fixing bolts(*16). (→ See figure, p.18.)
NOTE: For FTF and FTL models, fix frame to drive unit by tightening bolts and nuts(*21) into
attachment holes of drive side plate(*20).
8. If machine condition is unstable in operation, remove frame from drive unit and readjust installation
position.

BELT ALIGNMENT ADJUSTMENT

7-1. PRIOR CHECKING
1. Check frame for level, straightness, etc. → See p.10.
2. Check drive unit for position. → See p.19.
3. Check drive wheels, pulleys, etc. for dirt. → Clean and remove any foreign matter.
4. Check if V-form strip on belt undersurface has dislodged from belt guidance grooves.
→ Correct belt condition.

7-2. BELT ALIGNMENT ADJUSTMENT
FT/FTH model
Adjustment using head (or tail) pulley:
On side to which belt is deviating, turn adjustment screw(*2) clockwise. Pulley will then move outward on
this side and belt will center itself. Alternatively, on opposite side, if there is a space between pulley bracket
and frame, make adjustment on this side. In this case turn adjustment screw(*2) counterclockwise to
move pulley inward.
