3．Torque command (SPIN) (SLIN1,2)

Torque command inputs vs. peak current value Iop of Iosp or Ioo is expressed in the figure below:

The gain is defined by the inclination between two points.

(Please exclude the dead zone from the input voltage when calculating Iop. )

4．FG output (FG)）

3FG output begins after 900°degrees in electric angle, after the start mode ends and the BEMF detection starts. When

the rotational speed becomes 24rpm (Max.) or less in case of brake, the FG output is fixed to high.

The above-mentioned rotation speed applies to the 12 pole motor.
