Standard Connections

Standard Connections
3-phase 200 V AC
Single-phase 200 V AC (see note 1)
3-phase 400 V AC
FREQ adjuster
(2 kΩ, 1/4 W min.)
Note: 1. Connect single-phase 200 V AC to terminals R/L1 and S/L2 of the 3G3JV-ABj.
2. The braking resistor cannot be connected because no braking transistor is incorporated.
Input Method Selection
Switches SW7 and SW8, both of which are located above the control circuit terminals, are used for input method selection.
Remove the front cover and optional cover to use these switches.
Sequence Input Method Selection
By using SW7, NPN or PNP input can be selected as shown below.

S1 to 5
Frequency Reference Input Method Selection
By using SW8, frequency reference voltage or current input can be selected.
Parameter settings are required together with the selection of the frequency reference input method.
