PARAMETERS
(Note) When the commercial power supply-inverter switch-over sequence function is activated with the
FR-A5AR mounted, a magnet contactor repeats switch on/off. Always use in the following
connection diagram.
1) Recommended connection example 1
Use inverter output terminals (Contact
signal, open collector signal) instead of
MC1 signals.
The phenomenon occurs when relay
output of the FR-A5AR is used as MC1
signal.
2) Recommended connection example 2
When using relay output of the FR-
A5AR, set the alarm output signal
(ABC) instead of the MC1 signal and
output it from contacts B and C.
