Control mode

(1) V/F Control (FR-B series only)
⋅ It controls frequency and voltage so that the ratio of frequency (F) to voltage (V) is constant when changing frequency.
(2) Advanced magnetic flux vector control (FR-B3 series only)
⋅ This control devides 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.
