6.2 Control
mode
V/F control (initial setting), advanced magnetic flux vector control and general-purpose magnetic flux
vector control are available with the inverter FR-E700SC.
V/F control
It controls frequency and voltage so that the ratio of frequency (f) to voltage (V) is constant when
changing frequency.
Advanced (general-purpose) magnetic flux vector control
●
This control divides the inverter output current into an excitation current and a torque current by
vector calculation and makes voltage compensation to flow a motor current which meets the load
torque. Before operation of a motor in advanced magnetic flux vector control, the self-setting of
motor data must occur.
●
General-purpose magnetic flux vector control is the same function as the FR-E500 series. For other
cases, select advanced 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, high efficiency motor (SF-JR, SF-HR 0.2 kW
or more) or Mitsubishi constant torque motor (SF-JRCA four-pole, SF-HRCA 0.2 kW to 15 kW). 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.
●
Wiring length from inverter to motor should be within 30 m. (Perform offline auto tuning in the
state where wiring work is performed when the wiring length exceeds 30 m.)
