2.0 THEORY OF OPERATION
2.1 Models
The MPT-90 is available is several Continuous rotation versions or in a Non-
Continuousconfiguration.Thecontinuousrotationversionsutilize anelectrical
slip ring assembly to allow for 360 degrees of pan rotation capability while
providing connectivity to the positioner and payload. Overall connectivity
between the base connector and the payload ports is limited by the number
of conductors in the slip ring, and models vary based on the types of signal
passed through the slip ring.
The Non-Continuous configuration is limited in azimuth rotation, but is factory
default set to 435° of total rotation, with the indicated 0° being the center of
that rotation. The user may set “limit rings” internal to the positioner that will
activate switches toreduce the amount of azimuth travelif desired. Limit rings
are also standard on the tilt mechanism for all models, set at ±90° from the
table top’s horizontal position. Additionally, all units have software adjustable
travel limits.
2.2 Mechanical
Each axis of rotation is rigidly attached to a large 60 tooth helical gear. These
gears are meshed with a worm gear (essentially a 1 tooth gear) that is part of
a steel shaft supported by tapered roller bearings, mounted in an aluminum
“carrier”. The bearings are pre-loaded to prevent lateral play, and the carrier
position is adjustable allowing the worm optimum mesh with helical gear, with
negligible backlash. With the exception of the backlash in the worm drive, the
pan & tilt axis of motion cannot move unless the worm gear is driving it. This
allows the payload to be locked in position even when power is removed.
Mechanical drive mechanisms for Pan and Tilt axis of motion are nearly
identical, with the exception of slight differences in the chain drive sprocket
ratios.
2.3 Position
Position is measured by incremental encoders mounted on-axis to the main
helical gear which read/report actual position inclusive of any system
backlash. Each encoder utilizes an “index” signal that occurs once per
revolution. This index signal is used during the factory installation homing
routine and calibrates the axis of motion 0° azimuth and 0° elevation absolute
position. Position is stored in memory when powered down, allowing the
positioner to know its position when powered up. Since worm gears of this
ratio lock the unit into position, no movement is expected in an unpowered
state, however, each time the axis of motion crosses the index pulse, the unit
will recalibrate position based on the initial homing cycle.

2.4 Drive
The drive mechanism consists of two 1.8° stepper motors, driven by a 10:1
micro-step motor driver. The motor drivers are provided with DC source
voltage, and enable, direction and pulse signals. 2000 pulses are required for
the motor to turn 1 revolution. Each motor has a 12 tooth sprocket to drive the
worm-carriers via a chain drive. The chain is tensioned with an adjustable
idler,and thechainsdrive the carriers mentioned above. The pan carrieruses
a 28 tooth sprocket where the tilt uses a 30 tooth sprocket, giving the tilt a
slight increase in ratio reduction.
2.5 Electronics
The controller provides two fundamental types of moves: open loop “jog”
moves where the user specifies direction and velocity, and automated moves
where the controller is managing the move.
Stepper motors require starting at a nominally low speed, and may then be
accelerated by increasing the frequency of the pulse to the motordriver. In jog
mode, the unit will begin a move at a pre-determined speed and accelerate to
the commanded speed. When the jog command is terminated, the pulses
stop quickly decrease in frequency to zero, preventing an abrupt stop.
In automated moves, the microcontroller determines which direction it must
go, then manages the move by controlling acceleration, running at the
commanded speed during the move while monitoring position. The start
speed, acceleration rate and maximum move speed are user adjustable.
When the unit arrives at a pre-determined distance from the commanded
position, a deceleration process begins, slowing the unit to a stop at the
intended destination. User may set the distance from the final destination
where the slow down process starts. These adjustments allow the user to
tailor the motion profile to optimize for the type and size of the payload. For
example, you may wish to position a short range camera system with more
aggressive moves than a satellite dish, due to its size. A more complete
description of adjustments is in the protocol manual.
Additional electronic capabilities provide inner-connections between the
multiple serial ports on the unit, allowing the user to command the positioner
and payloads using various command methods.

2.6 Limits
Elevation range of motion may be limited in allmodels both electronically and
mechanically. Additionally, non-continuousrotationmodelshavelimitsettings
for the azimuth range of motion. “Soft Limits” are software settable, and are
primary method used to limit motion. The P&T units are shipped with the soft
limits set at the maximum range of motion, although the range of motion may
be limited by using the included software. Soft limits should always be set a
minimum of 0.2° beyond any position to be stored as a preset position; the
user should not set a preset position on a soft limit. Please refer to the
MN00307 Moog PTZ Controller Software Manual for instructions on how to
set the soft limits.
Mechanical switches to limit travel (“hard limits”) are provided on the elevation
for continuous rotation models, and on both axis of motion for non-continuous
models. These consist of plastic, moveable, color coded “trip rings” that
trigger a microswitch that tells the microcontroller to stop motion in that
direction, while allowing reverse motion. These should be considered a
secondary method of limiting motion, as there are software limits (“soft limit”)
provided as well. The default setting for the hard limits is slightly beyond the
default soft limit setting at the maximum range of normal motion for the
positioner and the user should not attempt to increase the range of motion
withoutconsultationwiththefactory. Additionally,itisrecommendedthathard
limits should always be set at minimum 2° beyond the soft limits. It is not
necessary for the user to adjust the hard limit settings unless they wish to
provide a secondary, redundant method of assuring the unit not travel beyond
the soft limits.

3.0 MPT -90 MODELS
MPT models are designed to have the maximum amount of features and flexibility in
connectivity based on our experience in remote controlled positioners. The MPTs
feature two “Payload Port” connectors (one per side) that allow the user to wire their
payloads to the positioner providing multiple power and control options.
All models provide the following conductivity to EACH of the payload ports:
Four 8-Amp conductors designed for power (up to 210 VDC, 240 VAC) to the
payloads. These conductors are shared between the two payload ports and
the base connector
Two analog (±12 VDC) variable speed drivers designed to drive Zoom and
Focus motors, but may be used for other devices such as low power motors
or lighting.
Two analog inputs, designed to read position potentiometers for Z/F lenses.
These are useful when combining with stored positions to assure consistent
camera framing of objects of interest.
One Auxiliary power source, configurable for 12 or 24 VDC, with on/off
switchable control
One Auxiliary power source, configurable for 5 or 12 VDC, with on/off
switchable control
Three serial ports, providing single ended (RS232) or differential (RS422)
communication between payloads.
Additionally, there are IP and Video signal paths between the base connector
and the payload port. In continuous rotation models, these signals pass through
the integrated slip ring, which creates limitations to the number of signals and
bandwidth that can pass through. The non-continuous rotation model (8-
PA166) does not have these limitation, and therefore has the higher bandpass
GigE and HD-SDI video connections on each payload port.
Each 10/100 IP signal path requires four conductors, while a GigE IP signal
path requires eight conductors. HD-SDI video requires different wiring and a
higher caliber of slip ring than conventional analog EIA - RS170 video, but not
all budgets can accommodate the higher cost of the HD-SDI slip ring.
For these reasons, several models have been created in various configurations,
and the table below shows the comparisons:

The General Purpose I/O conductors are typically used for powering devices connected
to Port 1 and/or Port 2. The conductor connected to pins 46 are twisted together with the
conductor connected to pins 49, likewise 47 & 48 are paired. These are conductors
through the slip ring oncontinuous models, allowing high current (up to 8A continuously)
connections to the payload. Both left and right side ports are connected to the base
allowing a single user supplied power supply to power loads on both sides, assuming
they are of the same voltage. The maximum continuous current rating through the slip
ring is8 amps,meaning thesumofboththeleftandrightside throughanyoneconductor
is not to exceed8A. The slip ring is rated up to 210VDC, and maybe used for ACcurrent
with a 500 VRMS dielectric strength in all combinations. Chassis Ground is internally
connected to the mechanical chassis of the positioner, and is available on all three
connectors. Chassis ground is not internally connected to any of the General Purpose
I/O ports, but may be connected externally if desired.

Typical 10/100 Ethernet connections require 2 sets of Twisted Pair (TP) conductors,
4 conductors total. Gig-E Ethernet connections require 4 sets of TP, a total of 8
conductors. Due to limitations of the conductor availability in the slip ring, the MPT
series allocates 8 conductors between the base connector and the payload ports.
Therefore, these conductors may be configured as two 10/100 Ethernet ports, one
to each side (Model 8-PB133 depicted above) or as a single Gig-E signal path to
either side (See next two pages).
Colors shown for IP signals per EIA/TIA 568B are to aid or reference external wiring
to the ports and do not represent actual color of conductors inside the positioner.
