The 5 LEDs in the cover of the regenerative power supply unit show the respective op-
erating state. Observe chapter ""LED signals"" (→
2 20). The same LEDs are also
located on the internal control board for easier checking during maintenance. There is,
however, a separate orange LED on the board; its function is assigned to the two-
color (green/orange) LED in the cover.

If a fault message is generated during the braking process, leading to the disconnec-
tion of the regenerative power supply unit, the regenerative power supply unit may not
be confirmed until the braking process is complete and the DC link voltage has
dropped to the default value.
We recommend that you block the pulse enable of the drive controller via the central-
ized alarm signal relay to prevent any problems that arise.
