Main Circuit Terminals - Omron V1000 Quick Start Manual

• For external control power supply use a UL Listed Class 2 power supply.
• Use twisted-pair or shielded twisted-pair cables for control circuits to prevent operating
faults.
• Ground the cable shields with the maximum contact area of the shield and ground.
• Cable shields should be grounded on both cable ends.

Main Circuit Terminals
The figure below shows the control circuit terminal arrangement. The drive is equipped with
screwless terminals
There are three DIP switches, S1 to S3, located on the terminal board
SW1
Switches analog input A2 between voltage and current input
SW2 Enables or disables the internal RS422/485 comm. port terminal resistance.
Used to select sourcing (PNP)/sinking (NPN, default) mode for the digital inputs (PNP requires
SW3
external 24 Vdc power supply)
