These inputs have all the programmable functions of the GP inputs plus these additional functions on [In8] & [In9]
which can be configured as single-ended or differential:
• PWM 50%, PWM & Direction for Velocity or Current modes
• Pulse/Direction, CU/CD, or A/B Quad encoder inputs for Position or Camming modes

DIGITAL InPUTS
Xenus has twelve digital inputs, eleven of which have programmable functions. Input [In1] is dedicated to the drive Enable function.
This is done to prevent accidental programming of the input in such a way that the controller could not shut it down.
Two types of RC filters are used: GP (general purpose) and HS (high speed). Input functions such as Pulse/Dir, CW/CCW, Quad A/B are
wired to inputs having the HS filters, and inputs with the GP filters are used for general purpose logic functions, limit switches, and the
motor temperature sensor. Programmable functions of the digital inputs include:
• Positive Limit switch
• Step & Direction, or CU/CD
• Negative Limit switch
step motor position commands
• Home switch
• Quad A/B master encoder
• Drive Reset
position commands
• PWM current or velocity commands
• Motor over-temperature
• CAN address bits
• Motion Profile Abort

PULL-UP/PULL-DOWn COnTROL
In addition to the active level and function
for each programmable input, the input
resistors are programmable in four groups
to either pull up to +5 Vdc, or down to
ground. Grounded inputs with HI active
levels interface to PLC’s that have PnP
outputs that source current from +24 Vdc
sources. Inputs pulled up to +5 Vdc work
with open-collector, or nPn drivers that
sink current to ground. The table below
shows the PU/PD groups and the inputs
they control.`
