Introduction
This manual describes the operational characteristics of the MC58000 Series Motion Processors from
PMD. These devices are members of PMD’s third-generation motion processor family.
Each of these devices is a complete chip-based motion processor. They provide trajectory
generation and related motion control functions. Depending on the type of motor controlled they
provide servo loop closure, on-board commutation for brushless motors, and high-speed pulse and
direction outputs. Together these products provide a software-compatible family of dedicated
motion processors that can handle a large variety of system configurations.
Each of these chips utilize a similar architecture, consisting of a high-speed computation unit, along
with an ASIC (Application Specific Integrated Circuit). The computation unit contains special on-
board hardware that makes it well suited for the task of motion control.
Along with similar hardware architecture these chips also share most software commands, so that
software written for one series may be re-used with another, even though the type of motor may be
different.

Family Summary
MC55000 Series – These chipsets provide high-speed pulse and direction signals for step motor
systems. For the MC55020 series two TQFP ICs are required: a 100-pin Input/Output (IO) chip,
and a 144-pin Command Processor (CP) chip, while the MC55110 has all functions integrated into a
single chip a 144-pin Command Processor (CP) chip.
MC58000 Series – This series outputs motor commands in Sign/Magnitude PWM or DAC-
compatible format for use with DC-Brush motors or Brushless DC motors having external
commutation; two-phase or three-phase sinusoidally commutated motor signals in PWM or DAC-
compatible format for brushless servo motors; pulse and direction output for step motors; and two
phase signals per axis in either PWM or DAC-compatible signals for microstepping motors.
For the MC58020 series two TQFP ICs are required: a 100-pin Input/Output (IO) chip, and a 144-
pin Command Processor (CP) chip, while the MC58110 has all functions integrated into a single 144-
pin CP chip.
1.2 How to Order
When ordering a single-chip configuration, only the CP part number is necessary. For two-IC and
multi-axis configurations, both the CP and the IO part numbers are required.

The CP chip is a self-contained motion processor. In addition to handling all system functions, the
CP chip contains the profile generator, which calculates velocity, acceleration, and position values for
a trajectory. When an axis is configured for servo motor control, a digital servo filter controls the
motor output signal. When an axis is configured for microstepping motor control, a commutator
controls the motor output signal. In either case, one of three types of output can be generated:
•
•
•
a Pulse-Width Modulated (PWM) signal output; or
a DAC-compatible value routed via the data bus to the appropriate D/A converter; or
a DAC-compatible value routed via the SPI port to the appropriate D/A converter
When an axis is configured for step motor control, the CP chip generates step and direction signals.
Axis position information returns to the motion processor in the form of encoder feedback using
either the incremental encoder input signals, or via the bus as parallel word input.
The MC58110 can co-exist in a CANOpen network as a slave device. It is CAN 2.0B compliant.

The IO chip contains the parallel host interface, the incremental encoder input along with motor
output signals that are configured as PWM or step and direction signals according to the motor type
selected for each axis.
The CP chip contains the profile generator, which calculates velocity, acceleration, and position
values for a trajectory. When an axis is configured for servo motor control, a digital servo filter
controls the motor output signal. When an axis is configured for microstepping motor control, a
commutator controls the motor output signal. In either case, one of three types of output can be
generated:
•
•
•
a Pulse-Width Modulated (PWM) signal output; or
a DAC-compatible value routed via the data bus to the appropriate D/A converter; or
a DAC-compatible value routed via the SPI port to the appropriate D/A converter
When an axis is configured for step motor control, the IO chip generates the step and direction
signals.
Axis position information returns to the motion processor in the form of encoder feedback using
either the incremental encoder input signals, or via the bus as parallel word input.
The MC58020 can co-exist in a CANOpen network as a slave device. It is CAN 2.0B compliant.

selectable via the host command SetPWMFrequency.
In 2 or 3-phase PWM 50/50 mode, PWMMag1A/1B/1C are the only signals
and encode both the magnitude and direction in the one signal.
In single-phase PWM sign/magnitude mode, PWMMag1A and PWMSign1A are
the PWM magnitude and direction signals respectively.
In 2-phase PWM sign/magnitude mode, PWMMag1A and PWMSign1A are the
PWM magnitude and direction signals for Phase A. PWMMag1B and
PWMMag1B are the PWM magnitude and direction signals for Phase B.
Unused pins should be left unconnected.
Refer to the User’s Guide for more information on PWM encoding schemes.
SPIEnable1
54
output
output
This pin provides the enable signal when SPI DAC output is active. The enable
is high when the DAC channel is being written to. At all other times the signal is
low.
SPI output can only be used when the axis being controlled is DC brushed or
when the amplifier expects a single-phase input and it performs brushless motor
commutation. PWM and Step and Direction output is not available when SPI
DAC output is selected.
If this pin is not used it may be left unconnected.
Pulse1
56
This pin provides the pulse (step) signal to the motor. A step occurs when the
signal transitions from a high to a low state. This default behavior can be changed
to a low to high state transition using the command SetSignalSense.
If this pin is not used it may be left unconnected.
Direction1
AtRest1
54
52
output
output
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.
This signal indicates that the axis is at rest and the step motor can be switched to
low power or standby mode. A high level on this signal indicates the axis is at
rest while a low signal indicates the axis is in motion.

input
These pins should be connected to the A and B quadrature signals from 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 5.0 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.
If these pins are not used they may be left unconnected.
~Home1
75
input
input
This pin provides the home signal, a general-purpose input to the position
capture mechanism. A valid home signal is recognized by the motion processor
when ~Home transitions from high to low.
If this pin is not used it may be left unconnected.
QuadAuxA1
QuadAuxB1
~Index1
88
81
69
If index capture is required, the encoder A and B signals connected to QuadA1
and QuadB1 signals must also be connected to QuadAuxA1 and QuadAuxB1.
The index pin should be connected to the index signal from the incremental
encoder. A valid index pulse is recognized by the motion processor when this
signal transitions from high to low.
If these pins are not used they may be left unconnected.
WARNING! 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.
Hall1A
Hall1B
Hall1C
18
14
37
input
Hall sensor inputs. These signals encode 6 valid states as follows: A on, A and B
on, B on, B and C on, C on, C and A on. A sensor is defined as being on when
its signal is high. On power-up or after reset these signal defaults to active high
interpretation, but the interpretation can be set to active low interpretation using
the SetSignalSense instruction.
Note: These signals should only be connected to Hall sensors that are mounted
at a 120° offset. Motors with hall signals 60° apart will not work.
The number of available axes determines which of these signals are valid.
If these pins are not used they may be left unconnected.
ParallelEnable
8
input
This signal enables/disables the parallel communication with the host. If this
signal is tied high, the parallel interface is enabled. If this signal is tied low the
parallel interface is disabled. Contact PMD for more information on parallel
communication.
WARNING! This signal should only be tied high if an external
logic device that implements the parallel communication logic is
included in the design.
~HostInterrupt 131
output
When low, this signal causes an interrupt to be sent to the host processor.
Synch
21
input/output This pin is the synchronization signal. In the disabled mode, the pin is
configured as an input and is not used. In the master mode, the pin outputs a
synchronization pulse that can be used by slave nodes or other devices to
synchronize with the internal chip cycle of the master node. In the slave mode,
the pin is configured as an input and should be connected to the Synch pin on
the master node. A pulse on the pin synchronizes the internal chip cycle to the
signal provided by the master node.
If this pin is not used it may be left unconnected.

This signal is asserted high to write a host instruction to the motion
processor, or to read the status of the HostRdy and HostInterrupt signals. It
is asserted low to read or write a data word.
HostRdy
8
output
This signal is used to synchronize communication between the motion
processor and the host. HostRdy (HostReady) will go low indicating host
port busy at the end of a read or write operation according to the
interface mode in use, as follows:
Interface Mode HostRdy goes low
8/16
after the second byte of the instruction word
after the second byte of each data word is transferred
after the 16-bit instruction word
16/16
after each 16-bit data word
HostRdy will go high, indicating that the host port is ready to transmit,
when the last transmission has been processed. All host port
communications must be made with HostRdy high (ready).
A typical busy-to-ready cycle is 10 microseconds, but can be substantially
longer, up to 50 microseconds.

input
This signal is the write-enable strobe. When low, this signal indicates that data is
being written to the bus.
This signal is the read-enable strobe. When low, this signal indicates that data is
being read from the bus.
~Strobe
R/~W
96
This signal is low when the data and address are valid during CP
communications. It should be connected to IO chip pin 54, CPStrobe.
This signal is high when the CP chip is performing a read, and low when it is
performing a write. It should be connected to IO chip pin 53, CPR/~W.
This signal is the inverse of R/~W; it is high when R/~W is low, and vice versa. For
some decode circuits and devices this is more convenient than R/~W.
Ready can be pulled low to add wait states for external accesses. Ready indicates
that an external device is prepared for a bus transaction to be completed. If the
device is not ready, it pulls the Ready pin low. The motion processor then waits
one cycle and checks Ready again.
