12.6.6

Brake resistor utilisation

The simulation of device-internal monitoring functions serves for the evaluation of the power de-

mand by DSD and the determination of the utilisation of the brake resistor.

• Use brake resistors with a monitoring function (e.g. thermal contacts) to ensure that the mains

contactor is switched off in the event of an overload.

12.6.6.1

Brake resistor on the inverter

The following inverters have an integrated brake transistor to which brake resistors can be connect-

ed to.

• Servo Drives 9400
• Inverter Drives 8400
• Inverter Drives 8400 protec
• Inverter Drives 8400 motec
