4. Parameter description
Parameter
<Setting>
• When P.65=0, retry is invalid. When alarm occurs, the voltage output is stopped, the ‘Alarm’ lamp
is lit, and all the inverter functions are disabled.
• When P.65=1, in case ‘over-voltage between P-N’ occurs, the voltage output is stopped. After a
period of waiting time (the set value of P.68), the retry is executed.
• When P.65=2, once ‘over-current’ occurs, the voltage output is stopped. After a period of waiting
time (the set value of P.68), the retry is executed.
• When P.65=3, in case ‘over-voltage between P-N’ or ‘over-current’ occurs, the voltage output is
stopped. After a period of waiting time (the set value of P.68), the retry is executed.
• When P.65=4, retry is effective. When alarm occurs, the voltage output is stopped. After a period of
waiting time (the set value of P.68), the retry is executed.
• When P.67=0, Retry is invalid.
• When P.67
≠
0, given continuous alarm occurs for times within the pre-defined upper limit of P.67,
retries will be valid. However, once the upper limit is exceeded, the retry is valid no more.
• For each time the retry occurs, the value of P.69 will be increased by 1 automatically, so the number
of P.69 read from the memory just indicates the number of retry accumulation times.
• If P.69 is rewritten with 0, the number of retry executed is erased.
Note: The inverter will retry until the return wait time of P.68 is past. Therefore, this function is selected, the
operator may cause danger, please be careful.

<Setting>
• When P.71=0, it is now idling braking. The output of the inverter will terminate immediately after
pressing
STOP
RESET
, and the motor will be ‘racing’
• When P.71=1, it is now beeline brake. The output of the inverter will follow the
acceleration/deceleration curve after pressing
