{ 100 }
With this parameter it is possible to program a manual (peak) power limit for the brake resistor.
The switch-on delay (modulation level) for the chopper can only rise to a certain maximum
specified limit. Once this value has been reached, irrespective of the level of the link voltage, the
inverter switches off the current to the resistor.
The result would be an overvoltage switch-off of the FI.
The correct percentage value is calculated as follows:

• Use of an external braking resistor: DIP switch S1:8: Setting „0“ (Off). Set the parameter
according to the braking resistor which is used.
• Use of an internal braking resistor: DIP switch S1:8: Setting „I“ (On). Settings in the
parameter do not have any effect.
