Pin Name and number Direction
~Index1
69 input
Description
This pin provides the Index signal for the incremental encoder. A valid index
pulse is recognized by the chip when this signal transitions from high to low.
There is no internal gating of the index signal with the encoder A
and B inputs. This must be performed externally if desired. Refer
to the Application Notes section at the end of this manual for an
example.
~Home1
70 input
This pin provides the Home signal, general-purpose inputs to the position-
capture mechanism. A valid Home signal is recognized by the chip when ~Home
goes low.
WARNING! If this pin is not used, its signal should be tied high.
PosLim1
63 input
This signal provides input from the positive-side (forward) travel limit switch.
On power-up or Reset this signal defaults to active low interpretation, but the
interpretation can be set explicitly using the SetSignalSense instruction.
WARNING! If this pin is not used, its signal should be tied high.
NegLim1
64 input
This signal provides input from the negative-side (reverse) travel limit switch. On
power-up or Reset this signal defaults to active low interpretation, but the
interpretation can be set explicitly using the SetSignalSense instruction.
AxisOut1
AxisIn1
Vcc
WARNING! If this pin is not used, its signal should be tied high.
This signal is an output during device reset and as such any
connection to GND or V_cc must be via a series resistor.
94 output
This pin can be programmed to track the state of any bit in the status registers.
If this pin is not used it may be left unconnected.
72 input
This is a general-purpose or programmable input. It can be used as a breakpoint
input, to stop a motion axis, or to cause an Update to occur.
If this pin is not used it may be left unconnected.
2, 7, 13, 21, 35, 36, 40, CP digital supply voltage. All of these pins must be connected to the supply
47, 50, 52, 60, 62, 66, voltage. V_cc must be in the range 4.75 - 5.25 V
93, 103, 121
WARNING! Pin 35 must be tied HIGH with a pull-up resistor. A
nominal value of 22K Ohms is suggested.
GND
AGND
unassigned
unassigned
3, 8, 14, 20, 29, 37, 46, CP ground. All of these pins must be connected to the power supply return.
56, 59, 61, 71, 92, 104,
113, 120
78-81
These signals must be tied to AnalogGND.
If the analog input circuitry is not used, these pins must be tied to GND.
45, 48, 49, 51, 54, 55, These signals may be connected to GND for better noise immunity and reduced
73, 90, 91, 108, 109 power consumption or they can be left unconnected (floating).
5, 30-34, 38, 39, 42, These signals must be left unconnected (floating).
