■ Caution When Using brushless 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/ STAND-BY switch. If installing aseparate RUN/ STAND-BY switch and operating the machine by external control, be
sure to use the control circuit terminal on the rear of controller unit. (For reversible
operation, set the reverse switch to REV.)
3. The RUN/ STAND-BY switch of control 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 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 0℃ 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 “Brushless-inverter instruction manual”, appendix.
