Parameterizing a motor holding brake

Motor holding brake applications
The motor holding brake prevents the motor turning when the inverter is switched-off. The
inverter has internal logic to control a motor holding brake.
The motor holding brake control inside the inverter is suitable for the following typical
applications:
● Pumps
● Fans
● Horizontal and vertical conveyors

Parameters to enable and set dynamic braking
Description
Extended access
Deactivate the V controller
DCmax
Enable signal and ON period of dynamic braking
0: Dynamic braking is locked
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
**) SIEMENS resistors are designed for 5% ON period
