Information
Use braking resistors with thermal monitoring (see the chapter Braking resistor [}65]).
6.2.1.6 Fast discharge
Fast discharge is activated when no power supply is present for 20s and the DC link voltage
has reduced over this time. For active fast discharge, the DC link is discharged via the brake
chopper and the braking resistor. Fast discharge does not take place for constant or increasing
DC link voltage as this behavior indicates a second supply module in the DC link group. If the
temperature sensor of the braking resistor is active, the fast discharge also remains off.
6.2.1.7 Status output
The relay status output of terminal X100 in conjunction with the 3 diagnostic LEDs on the front
of the device provides information about the status of the supply module.
