5.4.3.2 Control terminals on OPTA1
Here you see the basic description of the terminals of the I/O board and the relay board. For more
information, see Jumper selections on the OPTA1 basic board. For more information on control
®
terminals, see VACON
Reference potentiometer,
1-10kΩ
*) See Fig. 26 Jumper blocks on OPTA1.
Parameter references for I/O on keypad and NCDrive are: An.IN:A.1, An.IN:A.2, DigIN:A.1, DigIN:A.2,
DigIN:A.3, DigIN:A.4, DigIN:A.5, DigIN:A.6, AnOUT:A.1 and DigOUT:A.1.
To use the control voltage output +24V/EXT+24V:
• you can wire the +24V control voltage to digital inputs through an external switch.
• you can use the control voltage to power up external equipment, such as encoders and
auxiliary relays.
Note that the specified total load on all available +24V/EXT+24V output terminals must not exceed
250mA. The maximum load on the +24V/EXT+24V output per board is 150mA.
