Ultra5000 Connector Information

Digital Inputs

There are sixteen general purpose digital inputs. They are not
connected in hardware to perform a particular function. All digital
inputs have the same hardware configuration, shown in

Figure 2.8

.

Inputs 1 and 2 use high-speed circuitry, with minimal propagation
delays, suitable for use in registration applications. Any input can be
assigned through firmware to latch the motor or auxiliary position in
hardware.

The following table provides a description of the digital input
specifications.

IMPORTANT

Configure your digital inputs, in a group, as active
high (current sinking) or active low (current
sourcing).
