Operation is automatically
switched to the commercial
power-supply operation at inverter
fault. (Not switched when an
external thermal error occurs.)

inverter and commer-
cial power-supply
operation

Set the frequency to switch the
inverter operation to the commer-

Valid during automatic switchover
operation (Pr.139
≠
9999)
When the frequency command
decreases below (Pr. 139 to
Pr. 159) after operation is
switched from inverter operation
to commercial power-supply oper-
ation, the inverter automatically
switches operation to the inverter
operation and operates at the fre-
quency of frequency command.
When the inverter start command
(STF/STR) is turned off, operation
is switched to the inverter opera-
tion also.
✔ ✔ ✔
9999
Valid during automatic switchover
operation (Pr.139
≠
9999)
When the inverter start command
(STF/STR) is turned off after oper-
ation is switched from the inverter
operation to commercial power-
supply inverter operation, opera-
tion is switched to the inverter
operation and the motor deceler-
ates to stop.
