Fault - DC bus overvoltage

DC-bus voltage has exceeded the error threshold for overvoltage due to a too high braking energy or a too high mains voltage. The error threshold (display in 0x2540:006 (P208.06) results from the setting of the rated mains voltage in 0x2540:001 (P208.01).

Reduce dynamic performance of the load profile.

Check mains voltage.

Check settings for brake energy
management.

0x2541:001 (P706.01) = [0]: Connect brake resistor to the power unit and activate the integrated brake chopper

Fault

Fault - DC bus undervoltage

DC-bus voltage has fallen below the error threshold for undervoltage. The error threshold (display in 0x2540:003 (P208.03)) results from the setting of the rated mains voltage in 0x2540:001 (P208.01).

Warning

Motor overtemperature

The motor temperature sensor connected to terminals X109/T1 and X109/T2 measures a too high motor temperature.

• Motor too hot by impermissibly high currents.
• Motor too hot by frequent and too long acceleration processes.

• Check drive dimensioning.
• Check motor temperature sensor and wiring.

Fault (configurable)

• The event can only be reset after a blocking time.

External supply voltage critical

External supply voltage failed or too low.

• Check optional external 24V voltage supply (terminal X3/24E), if connected.
• Check mains voltage.

Warning

Warning - Internal fan

Warning of the internal fan.

Check/replace internal fan.
