Section 1
Introduction
The PMC200/200-P is a 2-axis motion controller designed to drive Newport
Model 495 and 496 integrated motorized rotation stages, and 850 Series
motorized drives. Utilizing motion control ICs and a Motorola 68000 host
processor, the PMC200/200-P performs all the position and velocity control
for each axis. This is a digital control system, so analog compensation and
velocity feedback are not necessary. The axes are set up and controlled in
an easy-to-learn, menu-driven environment. Using the setup routines, you
have complete control over axis movement, including setting absolute jog
step and compensating for backlash and positioning errors. A non-pro-
grammable version (PMC200) without RS232 and IEEE-488 interfaces is
available. Model PMC200 controllers may be upgraded to the PMC200-P at
the factory.
The purpose of this manual is to document the setup and operation of the
Newport Corporation PMC200/200-P 2-Axis Motion Controller for use with
495 and 496 motorized stages, and 850 series motorized drives.
The PMC200/200-P was thoroughly tested and inspected before shipping.
Prior to unpacking the equipment, carefully inspect the outer containers for
signs of damage. If you find any damage, immediately notify the shipping
company and contact Newport Corporation for further instructions.
NOTE
Retain the original packing materials. They will be necessary if
reshipment of the product is in order. They can also be useful for
transporting the equipment to other locations.
The following table lists the components that you should have received
with your order.

Section 2
SystemOperation
The controller keyboard is the primary input device on the PMC200/200-P,
but a joystick may be used as well. The PMC200/200-P can operate in two
modes: Setup mode and Execute mode. In Setup mode, you “configure” the
PMC200/200-P for operation. In Execute mode, the controller accepts
motion commands.
The PMC200/200-P has three types of built-in output devices:
1. A Vacuum Fluorescent Display containing 2 lines of 20 ASCII
characters each.
2. LEDs on the front panel switches indicate the modes and states of
the controller.
3. An Audio Alarm indicates an actuator limit with an audible tone.
The alarm also acts as a general purpose audible indicator in the
following manner:
Beep on Power Up
Beep for 4 seconds on Self-Test Failure
Prior to operating the PMC200/200-P, there are a few preliminary steps to
be followed to set up the controller.
2.2.1 Rear Panel Connections
On the controller rear panel (refer to Figure 2-1), you will find a power cord
connector, a RESET button, and two 15-pin female D-Type connectors (one
for each axis).
1. Select the correct VAC setting on the power cord connector on the
rear panel to match your AC voltage. To do this:
a. Insert a flat-head screwdriver into the notch at the top of the
power cord connector and pry open the panel.
b. Rotate the drum until the desired voltage setting will show
through the window when the panel is closed.
c. If you need to replace a fuse, insert a screwdriver under the
fuse pull tabs and gently slide the fuse holders straight out.
Replace the fuses only with the same type and rating of fuse.
d. Gently press the panel shut.
2. Attach the power cord to the controller rear panel and to the power
source selected in step 1.
3. Actuators may be attached to the rear panel connectors any time
prior to power-up.

The PMC200/200-P controller front panel consists of 5 switches and 1
potentiometer per axis, plus an emergency stop switch (refer to Figure 2-2).
The PMC200/200-P can run in 2 modes:
Setup Mode: The PMC200/200-P is being configured for operation.
Execute Mode: The PMC200/200-P accepts and executes motion
commands.
The functions of the switches and pots depend upon which of the two
modes of operation you are running. Each switch has two labels, one above
and one below, e.g., the left-most switch is labeled STOP and EXIT. The
upper label is used in Execute mode and the lower label is used in Setup
mode. Sections 2.5.1 and 2.6.1 describe the functions of the switches in
each mode.

2.4 Power Up Sequence The PMC200/200-P has battery back-up memory which holds the latest
PMC200/200-P configuration parameters. If the front panel power switch is
pressed, the PMC200/200-P memory maintains the system parameter
configuration set at the time of the last power down. If the RESET button
(on rear panel) is pressed, the PMC200/200-P memory will be reset to the
system default parameters shown in Table 2-1.
2.4.1 Front Panel Power Switch
When the power switch is pressed, the following information is displayed
on the vacuum florescent display:
1. Two blank rows are displayed.
The software is carrying out a self-test. If the hardware passes the
test, an audible beep will be issued. If an error is detected, then an
error message will be displayed, accompanied by four audio beeps.
See Section 5 for help.
2. ROM Version X.X
Passed Self Test
The PMC200/200-P is now in Execute mode and is ready to accept com-
mands for motion. If the ‘No Actuator’ message is displayed, you will need
to enter SETUP mode and configure the axes (refer to Section 2.6).
When the PMC200/200-P is in Execute mode, the controller will be in either
RUN STATE or JOG STATE. You may access Execute mode at any other
time by pressing the [EXIT] switch (so that the SETUP switch LED is not
lighted).
2.5.1 Keyboard Functions in Execute Mode
In Execute mode, the labels above the front panel switches indicate the
functions of the controller as follows.
STOP This switch will stop both axes immediately. The posi-
tion servo however, remains active.
ZERO DISPLAY This switch zeroes the position display of the axis.
SET UP If neither axis is moving, this switch will cause the
system to enter SETUP mode. The LED will light up and
the display will show the last menu choice used. If
either axis is moving, the switch will be inactive.
RUN/JOG This switch toggles between RUN and JOG states for the
particular axis. The RUN or JOG LED will be lit indicating
the state of motion. If the axis is moving when the switch
is pressed, the axis will stop, but the position servo will
remain active.
EXECUTIVE Mode

REVERSE RUN STATE - If an axis is moving in the reverse direction,
pressing this switch will stop the motion. If the axis is
moving forward, pressing this switch will cause it to
reverse direction. When moving, the velocity of the axis
is controlled by the VELOCITY STEP SIZE potentiometer.
When an overload occurs or an end of travel limit is
encountered, the REVERSE LIMIT LED lights up and the
axis will stop, but the position servo will remain active.
JOG STATE - If the axis is not moving, pressing this switch
will initiate a step movement in the reverse direction. The
size of the step is determined by the VELOCITY-STEP SIZE
potentiometer. If an axis is in the act of jogging forward,
the switch will have no effect. When an overload occurs
or an end of travel limit is encountered, the REVERSE
LIMIT LED lights up and the axis will stop, but the posi-
tion servo will remain active. Note that the maximum
velocity will be the same value that was set during RUN
State.
FORWARD RUN STATE - If the axis is moving forward, pressing this
switch stops the motion. If the axis is moving reverse,
pressing this switch will cause it to move forward. When
moving, the velocity of the axis is controlled by the
VELOCITY-STEP SIZE potentiometer. When an overload
occurs or an end of travel limit is encountered, the
FORWARD LIMIT LED lights up and the axis will stop.
JOG STATE - If the axis is not moving, pressing this switch
will initiate a step movement in the forward direction.
The size of the step is determined by the VELOCITY-STEP
SIZE potentiometer. If an axis is in the act of jogging
reverse, the switch will have no effect. When an overload
occurs or an end of travel limit is encountered, the
FORWARD LIMIT LED lights up and the axis will stop, but
the position servo will remain active. Note that the
velocity will be the same value that was set during RUN
State.
RUN STATE - When the actuator is moving, the potenti-
ometer sets the real-time velocity of the actuator. The
setting of the potentiometer determines the maximum
velocity at which the actuator will move.
JOG STATE - The potentiometer varies the jog step size.
Note that the maximum velocity will be the same value
that was set during RUN State.

2.5.2 Output Devices in Execute Mode
Like the front panel switches, the functions of the output devices depend
upon the operating mode.
Display RUN STATE - The display shows the real time position
and real-time velocity of the axis. When the actuator is
not moving, the display shows the velocity setting of the
VELOCITY/STEP SIZE potentiometer. This value is used
as the maximum velocity in the Jog State.
JOG STATE - The display shows the real time position,
followed by the jog step size.
NOTE
When the PMC200/200-P is in operation, you may notice that the
display flickers, even when no axis motion is occurring. This is
normal for this type of display being used.
Front Panel LEDs SETUP LED - This LED will be off in Execute mode.
RUN LED - This LED will be lit in RUN STATE and off in
JOG STATE.
JOG LED - This LED will be off in RUN STATE and lit in
JOG STATE.
REVERSE LIMIT LED - The LED will be lit when the axis is
overloaded or has reached an end of travel limit in the
reverse direction. If lit, pressing the opposite direction
switch twice will clear the limit state and turn off the
LED.
NOTE: After pressing the [REVERSE] switch, the LED will
remain ON until the limit is cleared.
FORWARD LIMIT LED - The LED will be lit when the axis
is overloaded or has reached an end of travel limit in the
forward direction. If lit, pressing the opposite direction
switch twice will clear the limit state and turn off the
LED.
NOTE: After pressing the [FORWARD] switch, the LED
will remain ON until the limit is cleared.
Audio Alarm The Audio Alarm will sound if either axis overloads or
reaches an end of travel in either direction.
NOTE: If the limit is not cleared after pressing the
[FORWARD] or [REVERSE] switches the alarm will only
beep twice.
In Setup mode, the controller allows you to set parameters for actuator
movement through menu selections. Both axes must be stopped before
you may enter Setup mode. Press the [SET UP] switch to enter Setup mode.
The display will show the last menu choice selected.
