Description
Multi-purpose Address lines. These pins comprise the CP chip’s external address
bus, used to select devices for communication over the data bus.
They may be used for DAC output, parallel word input, or user-defined I/O
operations. See the Pilot Motion Processor User’s Guide for a complete memory map.
This is the clock signal for the Motion Processor. It is driven at a nominal
20MHz.
CP chip analog power supply voltage. This pin must be connected to the analog
input supply voltage, which must be in the range 4.5-5.5 V
If the analog input circuitry is not used, this pin must be connected to V_cc.
CP chip analog high voltage reference for A/D input. The allowed range is
AnalogRefLow to AnalogVcc.
If the analog input circuitry is not used, this pin must be connected to V_cc.
CP chip analog low voltage reference for A/D input. The allowed range is
AnalogGND to AnalogRefHigh.
If the analog input circuitry is not used, this pin must be connected to GND.
CP chip analog input ground. This pin must be connected to the analog input
power supply return.
If the analog input circuitry is not used, this pin must be connected to GND.
These signals provide general-purpose analog voltage levels, which are sampled
by an internal A/D converter. The A/D resolution is 10 bits.
The allowed range is AnalogRefLow to AnalogRefHigh.
Any unused pins should be tied to AnalogGND.
If the analog input circuitry is not used, these pins should be tied to GND.
This pins provides the pulse (also called step) signal to the motor amplifier. A
“step” occurs when the signal transitions from a high state to a low state. This
default operation can be changed using the SetSignalSense command. Refer
to the Pilot Programmer’s Reference for more information.
This pin indicates the direction of motion and works in conjunction with the
pulse signal. A high level on this signal indicates a positive direction move and a
low level indicates a negative direction move.
The AtRest signal indicates that the axis is at rest and the step motor can be
switched to low power or standby. A high level on this signal indicates the axis
is at rest. A low signal indicates the axis is in motion.
These pins provide the A and B quadrature signals for the incremental encoder.
When the axis is moving in the positive (forward) direction, signal A leads signal
B by 90°.
The theoretical maximum encoder pulse rate is 5.1 MHz. Actual maximum rate
will vary, depending on signal noise.
NOTE: Many encoders require a pull-up resistor on each signal to establish a
proper high signal. Check your encoder’s electrical specification.
