8135 DC bus voltage low

Description

Device reactions	Default reaction	Minimum reaction
Drive	D	E
Power supply	D	E

For drives: An attempt is being made to start the drive (ControllerEnable = True), but the DC bus voltage is too low.

For power supplies: An attempt is being made to enable the power supply (PowerSupplyCheck = on / 1), but the DC bus voltage is too low.

Device	Threshold
Lexium 52	420 Vdc in 400 Vac operation
Lexium 62	o420 Vdc in 400 Vac operation o220 Vdc in 230 Vac operation
Lexium 62 Power Supply	o440 Vdc in 400 Vac operation o240 Vdc in 230 Vac operation
Lexium 62 ILM	o420 Vdc in 400 Vac operation o220 Vdc in 230 Vac operation

Cause	Solution
ControllerEnable is TRUE, but the mains voltage is too low.	Verify and correct if necessary the mains voltage (see the technical data on the device); the mains contactor may not be connected.
If DC buses are connected in parallel, an error has occurred in a servo amplifier.	oLocate servo amplifier with error. oEliminate error.

Cause

Solution

ControllerEnable is TRUE, but the mains voltage is too low.

Verify and correct if necessary the mains voltage (see the technical data on the device); the mains contactor may not be connected.

If DC buses are connected in parallel, an error has occurred in a servo amplifier.

oLocate servo amplifier with error.

oEliminate error.
