Setting the parameters of PWM output 1: "Real speed (centered on 50%)": The parameters can be set for
the signal frequency of this output (must be identical to the one for PWM output 2).
If cyclical ratio = 0%
→ Motor running forward (CW) at maximum speed setpoint defined in In6.
If cyclical ratio = 50%
→ Real speed = 0 rpm.
If cyclical ratio = 100%
→ Motor running in reverse (CCW) at maximum speed setpoint defined in
In6.

Setting the parameters of PWM output 2 "Real torque (centered on 50%)": The parameters can be set for the
signal frequency of this output (must be identical to the one for PWM output 1) and the torque value
corresponding to a cyclical ratio of 100% (scaling).
If cyclical ratio = 0%
→ Braking torque supplied = "S2 torque".
If cyclical ratio = 50%
→ Torque supplied = 0 mNm.
If cyclical ratio = 100%
→ Motor torque supplied = "S2 torque".
