Analog Input
The
ANALOG _ IN
may be configured to sense one of four (4) input types:
• 0 - 5V
• 0 - 10V
• 0 - 20 mA
• 4 - 20 mA

Analog Input Wiring and Usage Examples
The analog input may be used in either voltage or current loop modes with two range settings
available for each mode:
• Voltage: 0 to 5V or 0 to 10 V
• Current: 0 to 20 mA or 4 to 20 mA
A typical use for the analog input would be to read the value from a sensor within an MCode
program and set a position or velocity based upon that value.
NOTE:
The Logic (Analog) ground pin is non-isolated (common with power ground.)
