287 1 0~1 ---
<Setting>
• Set P.287 to 0 to cancel the output end short-circuits protection function.
• When P.287 is set to 1, if the output end is short, the operation panel will display the “SCP”
abnormal alarm and the inverter will stop the output.
5.70 Alarm History Parameters (P.288~P.291)
P.288 “Alarm code display option”
P.289 “Alarm code”
P.290 “The latest alarm status selection”
P.291 “The latest alarm message”
● This paragraph provides the users with parameter-related information on alarm codes for frequency,
current, voltage, as well as the 12 alarm codes mentioned earlier. If P.996 operation is executed,
the abnormal codes and the status messages for the occurred alarms recorded by this set of
parameters will be all cleared.

Remarks
288 0 0~12
The value of P.288, 1~12, corresponds to the
abnormal codes of P.289’s alarm E1~E12.
289 0 ---
290 0 0~6
When P.290=1, P.291 corresponds to the frequency
when the alarm goes off.
When P.290=2, P.291 corresponds to the current when
the alarm goes off.
When P.290=3, P.291 corresponds to the output
voltage when the alarm goes off.
When P.290=4, P.291 corresponds to the
accumulation rate of temperature increase when the
alarm goes off.
When P.290=5, P.291 corresponds to the (+/P)-(-N)
voltage when the alarm goes off.
When P.290=6, P.291 corresponds to the runnig time
of inverter(P.293*1440+P.292) when the current
alarm occurs.
