Analog Input
Figure 3.10 illustrates the Analog to Digital converter (ADC) input, ADC1. Located on P3-5, it
may be used to read any analog signal with a range of ±10V. The analog signal ground must be
connected to the Analog Common on connector P3-4. The Analog Common is tied to earth
ground internally. The 10 bit ADC has a resolution of approximately 20 mV. This analog input
may be used as a general purpose analog input or as the feedrate input. Refer to the IQ Master
Instruction Manual for information about the use of this input.
