NOTE: 1. Be sure to confirm that the power source voltage is within the rated voltage range, before
turning ON the power source.
2. Be sure to start and stop the conveyor with RUN/STOP switch. When starting and stopping the
machine by external signals, use control circuit terminals on rear of inverter. (→See “Starting
and Stopping the Conveyor by External Signals”, p. 12.)
3. When leaving the conveyor unused for a long period, make sure that the power supply is off.
(The RUN/STOP switch is not for turning the power on and off.)
4. Before turning off the power supply, be sure to set RUN/STOP switch to “STOP” position,
otherwise there is a risk that the motor will restart rotating unexpectedly when powered.
Moreover make sure that RUN/STOP switch is in “STOP” position before turning on the
power supply.
■ Variable-speed Range of Brushless-inverter
(Torque at high speed can be used at low speed as well.)
Nominal speed (motor rotation: 2300 r/min) is determined as the lower limit of RED ZONE. Variable-
speed range up to the lower limit of RED ZONE is 1:76 (motor rotation: 30-2300 r/min).
By using RED ZONE up to the upper limit, it is possible to vary speed up to 1.3 times of nominal speed
(variable-speed range: 1:100, motor rotation: 30-3000r/min).
NOTE: Since motor rotation increases as the speed gets closer to the upper limit of RED ZONE, this will
increase noise and shorten service life of gear head. Use the machine at appropriate speed to
avoid these troubles.
