External Alarm (A090); External Fault (F091); Fault History - WEG CFW100 Programming Manual

Faults and Alarms

13.12 EXTERNAL ALARM (A090)

It is necessary to set the digital input Dix for "without external alarm". If DIx is inactive, the inverter will activate the
external alarm A090. When DIx is activated, the alarm message will automatically disappear from the HMI display.
The motor keeps running normally, regardless the state of this input.

13.13 EXTERNAL FAULT (F091)

It is necessary to set the digital input Dix for "without external fault". If DIx is inactive, the inverter will activate the
external fault F091. In this case, the PWM pulses are immediately disabled.

13.14 FAULT HISTORY

The inverter is able to store a set of data on the last three faults occurred, such as: fault number, current (P003),
DC link voltage (P004), output frequency (P005), power module temperature (P030).
