When setting parameters, refer to the instruction manual (applied) and understand instructions.
Specify operation mode at power on
(Pr.340)
When power is switched on or when power comes back on after
instantaneous power failure, the inverter can be started up in the
Network operation mode.
After the inverter has started up in the Network operation mode,
parameter write and operation can be performed from a program.
Set this mode for communication operation using the inverter RS-
485 communication.
You can set the operation mode at power on (reset) according to
the
Pr. 79
and
Pr. 340
settings.
Large starting torque and low speed torque are available with
General-purpose magnetic flux vector control.
If the following conditions are not satisfied, select V/F control since
malfunction such as insufficient torque and uneven rotation may
occur.
The motor capacity should be equal to or one rank lower than the
inverter capacity.
Motor to be used is any of Mitsubishi standard motor (SF-JR
0.4kW or higher), high efficiency motor (SF-HR 0.4kW or higher)
or Mitsubishi constant-torque motor (SF-JRCA 4P, SF-HRCA
0.4kW to 15kW). When using a motor other than the above (other
manufacturer's motor), perform offline auto tuning without fail.
Single-motor operation (one motor run by one inverter) should be
performed.
The wiring length from inverter to motor should be within 30m.
(Perform offline auto tuning in the state where wiring work is
performed when the wiring length exceeds 30m.)
Permissible wiring length between inverter and motor differs
according to the inverter capacity and setting value of
Pr. 72 PWM
frequency selection
(carrier frequency). Refer to
page 73
for the
permissible wiring length.
