4.11 Connecting a motor holding brake
Connecting a motor holding brake
You can use any converter digital output to control the motor holding brake.
If the current or voltage rating of the digital output is not su󹪟cient, then you must control
the motor holding brake through a coupling relay.

Figure4-47 Connect the motor holding brake to digital output DO0 of the converter via interface
relay K1.
To de󹪝ne which of the digital outputs of the converter is used to control the motor holding
brake, you must interconnect the corresponding digital output with the brake control signal:
• Digital outputDO0: p0730 = 52.12
• Digital outputDO1: p0731 = 52.12
4.12 Monitoring the temperature of the braking resistor
WARNING
Fire caused by an unsuitable or incorrectly installed braking resistor
Using an unsuitable or improperly installed braking resistor can cause 󹪝res and smoke to
develop. Fire and smoke development can cause severe personal injury or material damage.
• Only use braking resistors that are approved for the converter.
• Install the braking resistor in accordance with regulations.
• Monitor the temperature of the braking resistor.
