Understanding Ultra1500 I/O
Specifications
A description of the Ultra1500 input/output is provided starting below.
Digital I/O Power Supply
All Ultra1500 drives require an external 24V power supply for proper
operation of the digital inputs. The following table provides a description of
the digital I/O power supply.
Note: A single 24V power supply can be used to power the digital I/O on
multiple drives, provided the cumulative minimum current requirements
are met.
Digital Inputs
There are seven opto-isolated digital inputs. Any input can be configured for
one of the following functions using Ultraware software: Drive Enable,
Positive Overtravel, Negative Overtravel, Positive Current Limit, Negative
Current Limit, Fault Reset, Integrator Inhibit, Operation Mode Override, Zero
Speed Clamp Enable, Reset Multiturn Data, Preset Selects, Preset Direction,
Alternate Gain Select, Position Strobe, and Pause Follower.
Digital inputs are active low, current sourcing. All have the same configuration,
as shown in Figure 2.2.
