E2820 Braking resistor overload prewarning
Cause
Allowed deceleration of connected drives too high
Energy absorption capacity of braking resistor is
almost exhausted
Regenerated energy in machining cycle is too high
Continuous regenerative power and/or rotary drive
energy is too high
E2829 Not ready for power on
Cause
Resistors for loading DC bus capacitances still are
thermally loaded due to last loading process
DOK-INDRV*-GEN-**VRS**-WA01-EN-P
LSA Control S.L. www.lsa-control.com [email protected] (+34) 960 62 43 01
Supported by Firmware Variant:
Supported by Supply Unit:
90% of the energy absorption capacity of the braking resistor have been
reached.
Remedy
Reduce deceleration of connected drives
Switch power off with a delay in the case of OFF or
E-STOP (for regenerative supplies)
Increase cycle time or reduce maximum drive speed of
application
Check dimensioning of braking resistor and, if
necessary, increase dimensioning

Supported by Firmware Variant:
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.
Remedy
Wait until converter clears warning E2829
