Dynamic brake 

Parameterizing the dynamic brake 

An internal closed-loop chopper control (braking chopper) in the frequency inverter, which 

can control an external braking resistor, is required for a dynamic brake   
Dynamic braking converts the regenerative energy, which is released when the motor 

brakes, into heat.

Braking chopper in the frequency inverter 

 

Parameter  Description 
P1237 

Enable signal and ON period of the dynamic brake 
0: Dynamic brake is blocked 

1: 5% ON period 

2: 10% ON period 

3: 20% ON period 

4: 50% ON period 

5: 100% ON period 
The ON period set here is only effective if the braking resistor has reached its operating 

temperature. When required, a cold braking resistor is switched-in independent of this 

parameter 

 

 

WARNING 

 

If a braking resistor that is unsuitable is used, a fire could break out and severely damage 

the converter. 
The temperature of braking resistors increases during operation. For this reason, avoid 

coming into direct contact with braking resistors. Make sure that the devices are located at 

sufficient distances from each other and that proper ventilation is provided.
