4. [Basic operation] Operation methods of motor 4-2
4
9
The operation methods of the motor are panel run, terminal run, and communication run. In any
case, parameters should be set in advance.
This chapter explains how to set parameters that are basic of motor operation.
In addition, the basic operation methods for panel run and terminal run are introduced, using
examples.
To run/stop the motor, the following operations are required.
• Input a run command.
• Input a frequency command (motor speed).
• Input a stop command.
The operation methods of the motor are panel run, terminal run, and communication run.
To change the motor speed, control the output frequency of the inverter.
With this inverter, the run/stop command and the frequency command can be set individually.
• Set the input method of run/stop (run command) with the parameter <CMOd: Run command select>.
• Set the input method of the frequency command with the parameter <FMOd: Frequency command
select 1>.
Set the method to input each command and operate with that method.
â– Panel run
On the operation panel, input run/stop (run command) and frequency command.
When you press the [RUN] key on the operation panel, the motor starts running. When you press
the [STOP/RESET] key, it is stopped. Set the frequency command with the touch wheel and register
it as a setting value of the parameter.
Mandatory
action
• Use the inverter that conforms to specifications of the power supply and the three-phase motor
to be operated.
If you use the inappropriate inverter, not only will the three-phase motor not rotate correctly, but
it will cause serious accidents such as overheating and burning out.
• Take countermeasures against leakage current.
The leakage current through the stray capacitance of the input/output power wires of inverter
and motor can affect peripheral devices. In that case, please take countermeasures such as
reducing the carrier frequency or shortening the length of input/output power wires. When the
total wire length (total length between an inverter and motors) is more than 100m, if the trip
occurs with the motor no-load current, make enough space between phase wires or insert the
filter (MSF: motor-end surge voltage suppression filter).

Important
• For reasons of safety, some parameters cannot be changed while the inverter is running. For
details, refer to [11. 1], [11. 3].
