Chapter 6. Function Description (FUN)
6.4.8 Power ON Start Selection (FUN_58)
In case ‘No’ is set, the inverter can be operated only if the terminal should be ‘On’ again after it is ‘Off’
once. In case ‘Yes’ is set, the inverter starts to run at the instant the power is supplied to the inverter if FX
terminal input is ‘On’ or RX terminal input is ’On’. If the inverter starts to run while the motor is freely
rotating, first, the motor decelerates to a stop and restart.

CAUTION
Particular attention should be directed to this function due to potential hazard as motor starts to run
suddenly upon applying AC input power.
6.4.9 Restart after fault reset (FUN_59)
In case ‘No’ is set, the inverter can be operated only if the terminal should be ‘On’ again after it is ‘Off’ once. In case
‘Yes’ is set, the inverter starts to run at the instant the inverter fault is cleared if FX terminal input is ‘On’ or RX terminal
input is ’On’. At the time of the inverter trip, the motor start to coast to a stop because the inverter blocks the IGBT
gating signals. If the inverter starts to run while the motor is freely rotating, first, the motor decelerates to a stop and
restart. If set CON_49 [Speed search] to bit 1 from previous bit 2, operation begin by speed search function when fault
is reset.

CAUTION
Take caution for this function. When FUN_59 is set, motor runs immediately upon fault is reset.
6.4.10 Restart After Fault Reset
1) FUN_60 (Number of auto restart try)
2) FUN_61(Delay time before Auto restart)
This function prevents the permanet stop of the inverter due to the trip. The inverter automatically resets the fault
and restarts and continues to run after the fault occurs if the number of automatic restart is set and the inveter
operation is possible.
