Frequency command source
Run command source
*) SJ700D-****FEF3/FUF3 (Initial settings)
(1) I/O connections
ELB
*) Refer to 3.5.2 for changing the frequency command source and 3.5.3 for changing the run
command source.
(2) Operation
Frequency: Using the voltage source and current source to set the frequency command with analog
select terminal (AT terminal: OFF: Voltage command / ON: Current command).
* AT terminal is used to switch the analog input O and OI to which the inverter refers as the
frequency command. (e.g. When AT terminal is OFF, the inverter outputs the frequency
according to the voltage input given to the O terminal)
Run/Stop: Using the forward / reverse terminal to run and stop.
