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, DigIN:A.5,
DigIN:A.6, AnOUT:A.1 and DigOUT:A.1.
To use the control voltage output +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 available +24 V/EXT+24 V output terminals must not exceed 250 mA.
