Torque control

Torque control cannot be performed with the FR-E700 series. It is available with the FR-A700 and FR-V500 series. More Details >>

Parameter list

The setting memo of the parameter list seal is not provided with the FR-A500 Instruction Manual. More Details >>

Monitoring function of the FR-A800-R2R

Line speed command and Line speed pulse monitor can be monitored while the operation is stopping. Actual line speed monitor becomes "0" while the operation i... More Details >>

FR-A8AL

When the PG24 terminal and the PG terminal are shorted, 24 VDC power for the encoder can be supplied from the PG24 terminal. More Details >>

Motor heat generation at low-speed operation

When using the FR-A540-3.7K in Advanced magnetic flux vector control, operating the motor continuously under the 100% torque at up to 3 Hz does not cause a h... More Details >>

Influence on inverter at motor coasts to stop

An induction motor does not act as a power generator unless voltage is applied to it.Therefore, just rotating due to coasting does not affect the inverter. More Details >>

FR-A7AP, FR-A7AL

They are conducted. An internal circuit is built-in to prevent undesirable current of the encoder power supply and inverter. More Details >>

What applications are suitable?

Variable speed control of small-capacity motor and other applications for which small size and low cost are required. (Examples: Replacement for gears and pu... More Details >>
