E2014 PLC - Warning no. 4
E2026 Undervoltage in power section
Drive Controllers HMS, HMD,
Supply Unit HMV01.1
Cause
Power is switched off without previous drive
deactivation by means of drive enable ("AF")
Malfunction or overload of power supply
Mains failure
LSA Control S.L. www.lsa-control.com comercial@lsa-control.com (+34) 960 62 43 01
Supported by Firmware Variant:
In conjunction with technology functions the drive-integrated PLC allows
the user generating warnings (E2011 .. E2014) within the PLC program.
Cause and remedy of a PLC warning depend on the respective PLC
project (or the active Rexroth technology function) and are contained in
the respective description of the technology function.
E2014 - Attributes
Display:
E2014
Mess. no.:
E2014 (hex)
Supported by Firmware Variant:
Supported by Supply Unit:
The DC bus voltage value is monitored by the drive controller and the
supply unit.
If the DC bus voltage falls below the minimum value determined for the
HCS
drive or it reacts to "DC bus not ok" of the module bus (see value of
P-0-0114, Undervoltage threshold), the device generates the warning
E2026 if "non-fatal warning" has been set with regard to the reaction to
undervoltage in P-0-0118, Power supply, configuration.
If the DC bus voltage falls by 80 V below the command value of 750 V
direct voltage, the warning E2026 is displayed at the device. The circuit is
not interrupted yet!

Questions and answers
Our machine in Rexroth drive installation total 20 nos machine so facing issue shortly 5 drive folty 8060 erro so how to do
Error 8060 on Bosch Rexroth IndraDrive indicates an overcurrent in the power section. To resolve this issue for five machines, follow these steps for each machine:
1. Check the Load and Connections – Verify that the motor and power connections are correct and not causing excessive current draw.
2. Inspect the Power Section – Look for any visible damage or overheating signs in the power section.
3. Restart the System – Power off the drive, wait for the DC bus to discharge below 50V, and restart.
4. Adjust Parameters if Needed – Ensure that the drive’s current limits and motor settings are correctly configured.
5. Replace Faulty Components – If the issue persists, the power section may be defective and require replacement.
Repeat these steps for all five machines to ensure proper operation.

What is solution of 2110 fault in rexroth drive
The solution for the F2110 fault in Bosch Rexroth IndraDrive is:
1. If the failure occurs sporadically (firmware error), clear the error and contact the service department for a firmware update.
2. If the error occurs repeatedly, it indicates defective hardware. In this case, the control section or the entire device must be replaced.
3. Only Rexroth service engineers or specially trained users are allowed to replace the control section.
4. The procedure for replacing the entire drive controller is described in the Project Planning Manual for the power section.

The engine moves in manual mode but does not work in automatic mode. The error code is E2074. What should I do?
Error code F2074 indicates a defective motor encoder. To resolve this issue:
1. Check the position data reference – If the position data reference is incorrect, the encoder is defective.
2. Replace the motor or motor encoder – A faulty encoder can prevent movement in automatic mode.
3. Send the motor to the manufacturer’s service department for inspection.
If the issue persists, consult the service department for further assistance.

@Aleksand C0209incorrect encoder configuration error on drive controller display, red light fickering on drive comms port,
Please help me with the problem of the VM F2802 and E2810 errors on the Rexroth Indradrive M
The VM F2802 error on the Bosch Rexroth IndraDrive M indicates that the Phase-Locked Loop (PLL) is not synchronized.
The E2810 error means that the drive system is not ready for operation. This occurs when one or more drives in a system (connected via DC bus and module bus) signal an error, preventing the supply from being ready for power output. To resolve it, identify the drives signaling an error and remove the cause, or ensure all drives are in communication phase 4.
