90% of the energy absorption capacity of the braking resistor have been
reached.
Cause
Remedy
Allowed deceleration of connected drives too high
Reduce deceleration of connected drives
Energy absorption capacity of braking resistor is
almost exhausted
Switch power off with a delay in the case of OFF or
E-STOP (for regenerative supplies)
Regenerated energy in machining cycle is too high
Increase cycle time or reduce maximum drive speed of
application
Continuous regenerative power and/or rotary drive
energy is too high
Check dimensioning of braking resistor and, if
necessary, increase dimensioning

The mains voltage for power supply cannot yet be switched on for the
HCS03 converter; the device is not yet ready for loading the DC bus
capacitances.
Cause
Remedy
Resistors for loading DC bus capacitances still are
thermally loaded due to last loading process
Wait until converter clears warning E2829
