Warning Diagnostic Messages (Exxxx)
E2802 HW control braking resistor
Cause
DC bus voltage >900 V due to increased
regenerated braking energy
Braking resistor defective or not correctly connected
Hardware defect in brake control
LSA Control S.L. www.lsa-control.com [email protected] (+34) 960 62 43 01
Supported by Firmware Variant:
During the braking process the increasing DC bus voltage is reduced by
switching on the braking resistor. But when the regenerated braking
power is too high the DC bus voltage keeps increasing. The warning
E2802 is generated when the protective hardware circuit switches on the
braking resistor in the case of high voltages (>900 V).
Remedy
Check drive dimensioning and, if necessary, use
additional capacitance
Check function of braking resistor (incl. cabling and
connection)
Replace power section or entire drive controller
Note:
Only Rexroth service engineers or especially trained users are
allowed to replace the power section. The replacement of the
entire drive controller is described in the Project Planning
Manual for the power section.
