I/O
Enabled Output (P3-2)
The Enabled output is a normally open relay that is closed when the ULTRA Plus or IQ is enabled and
opened when the ULTRA Plus or IQ is disabled. Relay Common (P3-3) is the other contact of this relay.
The Enable relay will open if any fault occurs in the ULTRA Plus or IQ.
Ready Output (P3-1)
The Ready output is a normally open relay that closes when the ULTRA Plus or IQ is powered up with
no faults. Relay Common (P3-3) is the other contact of this relay. The Ready relay will open if any fault
occurs in the ULTRA Plus or IQ.
DAC1 Output (P3-6)
A 12-bit digital to analog converter is provided for setting analog voltages. The DAC1 instruction is
used to set the voltage. Refer to Part 5
•
Language Reference, DAC1, for more detailed information.
DAC1 Value
The DAC1 Value set in the Parameter menu, Outputs, establishes the default value for the digital to ana-
log converter output, in volts. This is the value the DAC1 output is set to on power-up and when a pro-
gram is not running. The range is ±10 volts with about 5 mV resolution (default setting is 0 volts).
ADC1 Input (P3-5)
The Analog to Digital Converter 1 (ADC) may function as a general purpose input or may be used to set
the feedrate. This choice is made in the Parameter menu, Inputs, dialog box.
If set to a general purpose ADC the ADC1 instruction is used to read the voltage. Refer to Part 5
•
Lan-
guage Reference, ADCn for more detailed information.
If the ADC1 input is used as feedrate input, the ADC1 input voltage can range from 0 to 10 volts, cor-
responding to 0 to 200% feedrate.
Encoder 2
Encoder 2 can perform three different functions: It can be used to input a second encoder, to pass
encoder 1 signals out to another device, or to read step and direction inputs from an indexer. These func-
tions are determined by the setting in the Parameter menu, Feedback Configuration dialog box.
