When setting parameters, refer to the instruction manual (applied) and understand instructions.
When using motors under General-purpose magnetic flux vector
control, the offline auto tuning can be executed to automatically
calculate the motor constant.
When executing the offline auto tuning under V/F control, set the
motor constant (R1) and the
Pr.298 Frequency search gain
required
for the frequency search at the automatic restart after
instantaneous power failure.
You can copy the offline auto tuning data (motor constants) to
another inverter with the PU (FR-PU07).
Even when motors (other manufacturer's motor, SF-JRC, etc.) other
than Mitsubishi standard motor (SF-JR 0.4kW or higher), high
efficiency motor (SF-HR 0.2kW or higher), and Mitsubishi constant-
torque motor (SF-JRCA 4P, SF-HRCA 0.4kW to 15kW) are used or
the wiring length is long (30m or more as a reference), using the
offline auto tuning function runs the motor with the optimum
operating characteristics.
The offline auto tuning conditions
A motor is connected.
The motor capacity is the same as or one rank lower than the
inverter capacity.
A high-slip motor, high-speed motor and special motor cannot be
tuned.
The maximum frequency is 120Hz.
As the motor may run slightly, fix the motor securely with a
mechanical brake or make sure that there will be no problem in
safety if the motor runs.
Special caution is required in vertical lift applications.
Note that tuning performance is unaffected even if the motor runs
slightly.
(1) Initial settings and specifications for RS-485
communication
(Pr.117 to Pr.124)
Used to perform required settings for RS-485 communication
between the inverter and personal computer.
There are two different communications: communication
using the PU connector of the inverter and communication
using the RS-485 terminals.
You can perform parameter setting, monitor, etc. using the
Mitsubishi inverter protocol or MODBUS RTU protocol.
To make communication between the personal computer
and inverter, initialization of the communication
specifications must be made to the inverter.
Data communication cannot be made if the initial settings
are not made or there is any setting error.
When making communication via the MODBUS RTU protocol (
Pr.549
=
"1"), the setting range is as indicated in parentheses.
