2.14: Inputs XE2/XP2/800-1782/800-1808
The XE2, XP2, and 800-1808 drives have 22 digital inputs and 2 analog inputs. The 800-1782, a
custom version of the XE2, has 20 digital inputs and 2 analog inputs
2.14.1: Digital Inputs
IN1,10,11,20,21 and 22 are general purpose Schmitt trigger single ended inputs with
programmable pull-up/down to +5 Vdc/ground and 1 μs RC filters (24 Vdc compatible). IN1,10,11
and 20 are connected on J12, IN21 and IN22 are connected on J10 and J11 respectively. IN2-IN5
and IN12-IN15 are single ended or differential programmable inputs connected on J12. IN6-9 and
16-19 are single ended opto-isolated inputs connected on J9.
The 800-1782 does not utilize IN21 and IN22 and dedicates IN16-19 to the output of optical limit
switches mounted on motors.
For a list of input functions, see the CME 2 User Guide.
Input Filters
Two types of input RC filters are used: GP (general-purpose) and HS (high-speed). Input reference
functions such as Pulse and Direction, Pulse Up/Pulse Down, and Quadrature A/B are wired to
inputs that have the HS filters, and inputs with the GP filters are used for general-purpose logic
functions, limit switches, and the motor temperature sensor.
Debounce Time
To prevent undesired multiple triggering caused by switch bounce upon switch closures, each
input can be programmed with a debounce time. The programmed time specifies how long an
input must remain stable at a new state before the drive recognizes the state. The debounce time
is ignored if the input is used as a digital command input.
Configure for Pull Up/Pull Down Resistors by Groups
Pre-defined groups of inputs can be programmed to have either an internal pull up or pull down
resistor.
2.14.2: Analog Inputs
Two programmable differential analog inputs, AIN1 and AIN2 are connected on J12. As reference
inputs they can take position/velocity/torque commands from a controller. If not used as command
inputs, they can be used as general-purpose analog inputs.
