Addition of the torque restriction function during acceleration and deceleration
(when using the FR-A5AP option)
For the former model inverter, the torque restriction level was same regardless of acceleration, deceleration
and constant speed. Now you can set torque restriction levels during acceleration and deceleration
individually.
REMARKS
This instruction manual supplement explains the new function of the FR-A5AP (option unit).For other functions, refer to the
instruction manual of the FR-A5AP (option unit).
• Explanation of function
When using vector control, you can set torque restriction levels during acceleration and deceleration
individually in Pr. 816 and Pr. 817. Set the torque restriction level during constant speed in Pr. 22 as
same as the former model.

REMARKS
When "9999" is set in Pr. 816 and Pr. 817, the torque restriction level during acceleration/deceleration also becomes the
same as Pr. 22. For details of Pr. 22, refer to the FR-A5AP instruction manual.

After the state where difference between
the set frequency and running frequency
is within ± 2Hz has persisted for 1s,
torque restriction level during acceleration/
deceleration (Pr. 816 or Pr. 817) shifts
to torque restriction level during
constant speed (Pr. 22).
