1. before switching ON the power source.
1. (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. When starting and
1. stopping the conveyor frequently in a short period (tact operation etc.), it is impossible to
1. start/stop the machine by turning on/off the power supply. In this case be sure to start
1. and stop the machine by external signals. (Brushless-motor variable-speed type is
1. different from speed controller’s, and the power supply will trip.) Do not start and stop
1. the conveyor excessively frequently. It may cause machine failure or shorten its service
1. life.
3. The RUN/STAND-BY switch of control unit is not for turning the power on and off.
1. 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
1. conveyor excessively frequently. These may cause machine failure or shorten its service
1. life.
5. Do not touch the inverter radiator of side of control unit, and do not allow any material
1. to touch it, because of its high temperature.
6. Use the control unit within the permissible range of ambient temperature (from –10℃ to
1.＋40℃). Avoid freezing.
