[1]*
Resistor
brake
A brake resistor is incorporated in the system for dissipation of surplus brake energy as heat. Connecting a
brake resistor allows a higher DC-link voltage during braking (generating operation). The resistor brake
function is only active in drives with an integral dynamic brake.
[2]
AC brake
Improves braking without using a brake resistor. This parameter controls an overmagnetization of the mo-
tor when running with a generatoric load. This function can improve the OVC function. Increasing the elec-
trical losses in the motor allows the OVC function to increase the braking torque without exceeding the
overvoltage limit.
N O T I C E
The AC brake is not as efficient as dynamic braking with resistor. AC brake is for VVC+ mode in both open
and closed loop.
Parameter 2-11 Brake Resistor (ohm)

2-11 Brake Resistor (ohm)
Default value: Size related
Parameter type: Range, 0 - 65535 Ohm
Setup: All setups
Conversion index: 0
Data type: Uint16
Change during operation: True
Set the brake resistor value in Ω. This value is used for monitoring the power to the brake resistor in parameter 2-13 Brake Power
Monitoring. This parameter is only active in drives with an integral dynamic brake. Use this parameter for values without decimals.
For a selection with 2 decimals, use parameter 30-81 Brake Resistor (ohm).
