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
drive (see value of
P-0-0114, Undervoltage threshold
) or it reacts to
"DC bus not ok" of the module bus, the device generates the error
message F2026 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 below 75% of the mains voltage crest value
that was detected when the mains contactor had been switched on, the
error F2026 is displayed at the device. Power is switched off!
