3 Operation and Test Run
Precautions for Safe Use
Operation and Adjustment
• Be sure to confirm the permissible range of motors and machines before operation because the
inverter speed can be changed easily from low to high.
• Provide a separate holding brake if necessary.
• Do not come close to the machine when selecting reset in the deceleration stop function (b050)
because the machine may abruptly start after the power is turned on.
• Provide a separate emergency stop switch because the STOP Key on the Operator may not function
depending on the settings and the status of the Inverter.
• When checking a signal during the power supply and the voltage is erroneously applied to the control
input terminals, the motor may start abruptly. Be sure to confirm safety before checking a signal.
• Even if the inverter power supply is turned off, the counter-electromotive force occurs while the PM
motor rotates, which may result in electric shock.
Do not remove the front cover or terminal block cover of the Inverter until the PM motor stops.
• Be sure to confirm the RUN command is not input before resetting the alarm because the machine
may abruptly start.
• When using the Digital Operator (3G3AX-OP01), ensure safety of the equipment before operating
the RUN key or the volume.
Precautions for Correct Use
Restart Selection Function
• Do not come close to the machine while RUN command is enabled. When the restart selection func-
tion (b001, b008) is set, the machine may start abruptly.
Motor Overload Protection
• For the motor overload protection, be sure to set the rated current of your motor to the Electronic
Thermal Level (b012/b212) and PM Motor Rated Current (H105).
