Supported by Firmware Variant:
In conjunction with technology functions the drive-integrated PLC allows
the user generating warnings (E2011 .. E2014) within the PLC program.

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!
