Note 1: The two terminals [L] are electrically connected together inside the inverter.
Note 2: We recommend using [L] logic GND (to the right) for logic input circuits and
[L] analog GND (to the left) for analog I/O circuits.
Note 3: Default relay N.O./N.C. configuration is reversed. See page 4-60 .
Wiring sample of control logic terminal (sink logic)
Note: If relay is connected to intelligent output, install a diode across the relay coil
(reverse-biased) in order to suppress the turn-off spike.
Caution for intelligent terminals setting
In turning on power when the input to the intelligent terminals become the following operations,
the set data might be initialized.
Please ensure not becoming the following operations, in changing the function allocation
of the intelligent input terminal.
