Rexroth driver E2818 fault repair:
E2818 Phase Interrupt, Single-Phase Main Contactor Interrupt Identified. As long as no undervoltage occurs in the bus, the power supply will not be cut off (F2026).
Cause: Damage to the main contactor safety device.
Cabling error. Workaround:
Replace the main contactor safety device.
Check and correct the wiring.
E2819 Main Contactor Power Down, Identification of Two- or Three-Phase Main Contactor Fault. As long as no undervoltage occurs in the bus, the power supply will not be cut off (F2026).
Cause: Damage to the main contactor safety device.
Cabling error. Workaround:
Replace the main contactor safety device.
Check and correct the wiring.
The E2814 main contactor** is now undervoltage and the peak voltage of the main contactor drops below the set peak during operation. The user can set the peak value through the P-0-0810, the minimum main contactor peak on a case-by-case basis.
Reason: The voltage of the main contactor drops when there is a load.
The main contactor voltage is too low when the power is turned on.
Solution: Check the design parameters of the main contactor wiring, and increase the power cord cross-section if necessary.
