Description
Without commercial power-sup-
ply switchover sequence
With commercial power-
supply switchover sequence
Set the operation interlock time of
MC2 and MC3.
Set the time slightly longer (0.3 to
0.5s or so) than the time from
when the ON signal enters MC3
until it actually turns on.
Inverter output is stopped (motor
coast) at inverter fault.
Operation is automatically
switched to the commercial
power-supply operation at inverter
fault. (Not switched when an
external thermal error occurs.)
Set the frequency to switch the
inverter operation to the commer-
cial power-supply operation.
Without automatic switchover
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.
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.
