14.8 REMOTE HMI COMMUNICATION ERROR FAULT (F701)
The condition for fault F701 is the same as that of alarm A700, but it is necessary that the HMI be the source for
some command or reference (HMI Keys option) in parameters P220 to P228.
14.9 AUTO-DIAGNOSIS FAULT (F084)
Before starting loading the factory default (P204 = 5 or 6), the inverter identifies the power hardware in order to
obtain information on the module voltage, current and trigger, the power module.
Fault F084 indicates something wrong happened during the identification of the hardware: nonexistent inverter
model, some loose connection cable or damaged internal circuit.
NOTE!
When this fault occurs, contact WEG.
14.10 FAULT IN THE CPU (F080)
The execution of the inverter firmware is monitored at several levels of the firmware internal structure. When some
internal fault is detected in the execution, the inverter will indicate F080.
NOTE!
When this fault occurs, contact WEG.
14.11 SAVE USER FUNCTION FAULT (F081)
This fault occurs during the attempt to save (P204 = 9) more than 32 parameters with values different from the
factory default (P204 = 5 or 6) or the Save User function is protected against writing.
14.12 COPY FUNCTION FAULT (F082)
In case the flash memory module (MMF) has been previously loaded with parameters of a "different" version from
that of the inverter to which it is trying to copy the parameters, the operation will not be executed and the HMI will
indicate fault F082. It is considered a "different" version those which are different in "x" or "y", assuming that the
number of the software versions are represented as Vx.yz.
14.13 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.
14.14 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.
