220 Parameters
40.07
IR-compensation
Defines the relative output voltage boost at zero speed (IR
compensation). The function is useful in applications with a
high break-away torque where direct torque control (DTC
mode) cannot be applied.

on page
0.00 … 50.00%
Voltage boost at zero speed in percent of nominal motor
voltage.
100 = 1%
40.10
Flux braking
Defines the level of braking power.
Disabled
Flux braking is disabled.
0
Moderate
Flux level is limited during the braking. Deceleration time is
longer compared to full braking.
1
Full
Maximum braking power. Almost all available current is used
to convert the mechanical braking energy to thermal energy
in the motor.

42 Mech brake ctrl
Mechanical brake control configuration. See also section

.
42.01
Brake ctrl
Activates the brake control function with or without
supervision.
Note:
This parameter cannot be changed while the drive is
running.
No
Brake control disabled.
0
With ack
Brake control enabled with supervision (supervision is
activated by parameter
).
1
No ack
Brake control enabled without supervision.
2
No.
