7. Operation with external signal
7.1 External operation
The inverter can be freely controlled externally.
Parameters must be differently set depending on the operation method. Make sure of the operation method before
setting parameters, and set parameters properly to the operation mode according to the procedure mentioned below.
[Steps in setting parameters]
Check of external si
nal conditions
In case of control panel operation the frequency
=(Operation panel input
enabled)
In case of set the frequency with external input
=
(VI/II (voltage/current input))
(RR/S4 (potentiometer/voltage input))
(RX (voltage input))
(2-wire RS485 communication input)
(4-wire RS485 communication input)
(Communication option input)
(Optional AI1 (Differential current
input))
(Optional AI2 (voltage/current input))
(External contact Up/Down)
(RP pulse input)
(High speed pulse input)
