Sequence output is not provided. (Pr. 136, Pr. 137, Pr. 138 and Pr. 139 settings
are ignored.)

1
Sequence output is provided.
When MC1 to MC3 are assigned with Pr. 190 to Pr. 195 (output terminal
function selection), open collector outputs are provided. When they are not
assigned, relay outputs are provided from the FR-A5AR (option).
136
MC switch-over
interlock time
0 to 100.0 s
Sets the MC2 and MC3 operation interlock time.
137 Start waiting time 0 to 100.0 s
Set a slightly longer (about 0.3 to 0.5 s) value than the time from when the ON
signal enters inverter operation MC3 to when it actually switches on.
0
Stops inverter operation and coasts the motor.
The inverter stops when an inverter fault occurs (both MC2 and MC3 switch off).
138
Commercial power
supply-inverter
switch-over
selection at alarm
occurrence
1
Stops inverter operation and automatically switches inverter operation to
commercial power supply operation.
When an inverter fault occurs, inverter operation is automatically switched to
commercial power supply operation (MC2: ON, MC3: OFF).
0 to 60.0Hz
The motor is started and run by the inverter up to the set frequency, and when
the output frequency reaches or exceeds the set frequency, inverter operation is
automatically switched to commercial power supply operation. Start and stop are
controlled by the inverter operation command (STF or STR).
139
Automatic inverter-
commercial power
supply switch-over
frequency
9999 Automatic switch-over is not done.
Note: 1. Pr. 139 functions when Pr. 135 setting is other than "0".
2. When the motor started by the inverter reaches the automatic switch-over frequency, inverter
operation is switched to commercial power supply operation. If the inverter's run command value is
then lowered to or below the switch-over frequency, commercial power supply operation is not
automatically switched to inverter operation.
Switch off the inverter operation command signal (STF or STR) to switch commercial power supply
operation to inverter operation and decelerate the motor to a stop.
