40.07 IR COMPENSATION FW block: MOTOR CONTROL (see above)
Defines the relative output voltage boost at zero speed (IR compensation). The function is useful in
applications with high break-away torque when no DTC motor can be applied.
This parameter is only effective when parameter 99.05 MOTOR CTRL MODE is set to (1) Scalar.
0…50% IR compensation.
40.10 FLUX BRAKING FW block: MOTOR CONTROL (see above)
Defines the level of braking power.
(0) Disabled Flux braking is disabled.
(1) Moderate Flux level is limited during the braking. Deceleration time is longer
compared to full braking.
(2) Full Maximum braking power. Almost all available current is used to
convert the mechanical braking energy to thermal energy in the motor.
