DC brake current
(DC brake current)
S P
0 ... 250 %
{ 100 }
Current setting for the functions of DC current braking (P108 = 3) and combined braking (P108 =
5).
The correct setting value depends on the mechanical load and the required deceleration time. A
higher setting brings large loads to a standstill more quickly.
The 100% setting relates to a current value as stored in the >Nominal current< parameter P203.
NOTE: The amount of DC current (0
Hz) which the FI can supply is limited. For this value,
please refer to the table in Section (chapter 8.4.3), column: 0 Hz. In the basic setting
this limiting value is about 110 %.

P110
Time DC-brake on
(DC braking time on)
S P
0.00 ... 60.00 sec
{ 2.00 }
The time during which current selected in parameter P109 is applied to the motor for the function
"DC braking" selected in parameter P108 (P108 = 3).
Depending on the relationship of the actual output frequency to the max. frequency (P105), the
>DC brake time< is shortened.
The time starts running with the removal of the enable and can be interrupted by fresh enabling.

25 ... 400 %
{ 100 }
Directly affects the behaviour of the drive at 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.

Torque current limit
(Torque current limit)
S P
25 ... 400 % / 401
{ 401 }
With this parameter, a limit value for the torque-
generating current can be set. This can prevent
mechanical overloading of the drive. It cannot provide any protection against mechanical
blockages (movement to stops). A slipping clutch which acts as a safety device must be provided.
The torque current limit can also be set over an infinite range of settings using an analog input.
The maximum setpoint (compare adjustment 100%, P403/P408) t
hen corresponds to the value
set in P112.
The limit value 20% of current torque cannot be undershot by a smaller analog setpoint
(P400/405 = 2). However, in servo mode with P300 = 1:
• up to SW version 1.9: not less than 10%
• SW version 2.0 and above: no restriction (motor torques from 0% are possible)!
401 = OFF means the switch-off of the torque current limit! This is also the basic setting for the FI.
NOTE: For lifting gear applications, a torque limit must not be used!
