E2086 Prewarning supply module overload
Imminent overload of power supply
Max. energy absorption capacity of braking resistor
E2800 DC bus timeout
Braking energy of connected drives is too high
Braking resistor defective
Supported by Firmware Variant:
The supply signals a warning regarding imminent overload via the module
bus. The warning is displayed at the drive controllers and can be
evaluated by the control master via the master communication. If there is
no relief, the module bus message "error supply module" and power off
(F2086) can occur.
Reduce required power by lower infeed velocity of tools.
Check dimensioning of supply
Check dimensioning of braking resistor and, if
necessary, increase dimensioning
