Current setting for the DC braking (P108 = 3) and combined braking (P108 = 5) functions.
The correct setting depends on the mechanical load and the required stopping time. A higher
setting can bring large loads to a standstill more quickly.
The 100% setting corresponds to a value for current as stored in parameter P203 >Rated
current<.
NOTE:
The possible direct current (0 Hz) that the VFD can supply is limited. Please refer to
the table in section 8.4.3 "Reduced overcurrent due to output frequency", 0 Hz
column, for this value. In the basic setting this limit is 110%.
DC braking: Not for PMSM motors!

{ 2.00 }
The time during which the current selected in parameter P109 is applied to the motor for the "DC
braking" function selected in parameter P108 (P108 = 3).
The >DC brake time< is shortened depending on the ratio of the prevailing output frequency to
the max. frequency (P105).
The time starts running when the enable is removed and can be interrupted through a re-
enabling.

Directly affects the behavior of the drive at the torque limit. The basic setting of 100% is sufficient
for most drive tasks.
If values are too high, the drive tends to vibrate as it reaches the torque limit.
If values are too low, the programmed torque limit can be exceeded.

25 ... 400%/401
{ 401 }
A limit for the torque-generating current can be set with this parameter. This can prevent
mechanical overloading of the drive. However, it cannot provide any protection against
mechanical blocks (movement to stops). A slipping clutch acting as a protective device is
essential.
The torque current limit can also be set over an infinite range of settings using an analog input.
The maximum setpoint (cf. 100% calibration, P403[-01] . .[-06]) then corresponds to the setting in
P112.
The 20% current torque limit cannot be undershot even by a smaller analog setpoint (P400[-01]
… [-09] = 11 or 12). However, in servo mode ((P300) = "1") a 0% limit is possible as of firmware
version V 1.3 (older firmware versions: min. 10%)!
401 = OFF
stands for the torque current limit switch-off! This is also the basic setting for the
VFD.
