Parameter references for I/O on control panel and NCDrive are: An.IN:A.1, An.IN:A.2, DigIN:A.1, DigIN:A.2, DigIN:A.3, DigIN:A.4, Dig-
IN:A.5, DigIN:A.6, AnOUT:A.1 and DigOUT:A.1.
To use the control voltage 24 V/EXT+24 V:
Wire the +24 V control voltage to digital inputs through an external switch. OR
Use the control voltage to power up external equipment, such as encoders and auxiliary relays.
The specified total load on all ava24 V/EXT+24 V output terminals must not exceed 250 mA.
The maximum load on the +24 V/EXT+24 V output per board is 150 mA. If there is a +24 V/EXT+24 V output on the board, it is locally
short circuit protected. If one of the +24 V/ EXT+24 V outputs short circuits, the others remain powered because of the local protec-
tion.
