What Is the 1746-QS Module?
What Is the
Hydraulic Configurator
This chapter presents a conceptual overview of how you use the
1746-QS module in an application.
The 1746-QS Synchronized Axes Module provides four axes of
closed-loop synchronized servo positioning control, and lets you
change motion parameters while the axis is moving. The module has
four optically isolated inputs for signals from linear displacement
transducers (LDTs) and four optically isolated 10 volt outputs that
interface with proportional or servo valve amplifiers.
The module’s microprocessor provides closed-loop control. The
module reads the axis position and updates the drive output every
two milliseconds, for precise positioning even at high speeds.
The module is designed for use with the Hydraulic Configurator, a
software product that you can obtain from the Allen-Bradley website on
the Internet. The Hydraulic Configurator is an interactive executable
that lets you configure the module and tune its axes. With it, you can:
• configure axes and store configuration parameters
• tune each axis independent of the ladder program
• store multiple commands to initiate repetitive axis motion
• display a log of the last 64 motion commands sent to the module
• observe and/or store plots of each axis
• access help screens that explain and/or describe module features
What Is an SLC-500 System?
Important: The Hydraulic Configurator saves considerable time when
tuning axes and troubleshooting faults. Thereafter, your ladder logic
sequences module operation with the machine.
The Allen-Bradley Small Logic Controller (SLC) system is a programmable control system with an SLC processor, I/O chassis containing
analog, digital, and/or special-purpose modules, and a power supply.
The 1746-QS module occupies one slot of the I/O chassis and
communicates with the SLC processor over the backplane using 32
words in the SLC processor’s output image table and 32 words in the
input image table. The processor loads or reads the module’s
configuration parameters using M0 or M1 files, respectively. Your
ladder logic sequences synchronized axes movement with machine
operation. The system can be illustrated as follows:

Because you can interact quickly and easily with the module’s control of
axis motion via the Hydraulic Configurator, this control system has
these benefits:
• faster setup and tuning of axes – the Hydraulic Configurator lets you
quickly set up and tune each axis independent of your ladder program.
• reduced cycle time – you can increase axis speed for faster operation
• smoother operation for longer machine life – you can profile acceler-
ations and decelerations of the hydraulic actuator to limit pressure spikes
• faster change-over to new parts – you can store setups (configuration
parameters) for quick an accurate change-over between parts
How Does It Work?
Publication
1746-6.19 March 1998
Monitoring Axis Position
The module has four LDT inputs. You configure each axis for an LDT
with a Pulse Width Modulated output (DPM) or a Start/Stop output
(RPM) by changing axis configuration parameters.
Controlling Axis Output
The module is a targeting controller: every two milliseconds its microprocessor updates
point-to-point moves,
resulting speed, accelerations, and decelerations follow either a
trapezoidal or s-curve profile.
TARGET POSITION and target SPEED values. For
TARGET POSITIONS are generated so that
1–3
The MODE, ACCELERATION, DECELERATION, SPEED, and
COMMAND VALUE (requested position) are used to generate the
profile. You send these command words to the module through the
processor’s output image table. You may change them “on-the-fly“
while the axis is moving.

The module compares ACTUAL POSITION with TARGET POSITION to
determine position error. Every update, it uses the position error to adjust
drive output. PID gains are adjustable and can be applied selectively.
The module also provides two different feedforward algorithms;
EXTEND/RETRACT FEEDFORWARD, and EXTEND/RETRACT
ACCELERATION FEEDFORWARD. These feedforward terms provide
additional drive output to help the axis follow the target, freeing the
PID loop to correct for system nonlinearity and changes in load.

Programming
A sample ladder program for the module is available from
Allen-Bradley’s website on the Internet. You can download it as an
executable file to your PC’s disk drive and transfer it to your SLC
processor. But, you must modify it for your application.
Publication
1746-6.19 March 1998

Ladder logic transfers motion commands to the module and axis
status from the module thru the I/O image table. Ladder logic also
copies configuration parameters to the module’s M0 file at power up.
It also copies configuration parameters (that you enter/change with
the Hydraulic Configurator) from the module’s M1 file to processor
files. Thus, you can establish a library of configurations (recipes) in
processor files that you can select and download to the module at
power up or each time you want to change the setup of your axes.
We explain the functions of the ladder logic later in this manual.
What Are Typical Applications?
System Requirements
Use the module in an SLC-based system for control of hydraulic
applications where two or more axes must reach their final position
at the same time, such as:
• plywood presses
• roll positioning
• palletizers and stackers
• forging machines
• hydraulic tailgate loaders
In addition, the module is designed to support independent axes using
either servo or proportional amplifiers, and retrofit into existing
hydraulic systems requiring a positive voltage irrespective of direction.

Important: Signals in this type of control system are very susceptible to
radiated electrical noise. The module is designed to detect loss-of-sensor
and sensor noise conditions for any of the four axes when position values
are lost or corrupted. The Hydraulic Configurator displays these
conditions in the Status word window. The resulting hard or soft stop
depends on how you configured autostop conditions. (See Hydraulic
Configurator, Config word, and click on autostop “Help“).
To minimize interference from radiated electrical noise with correct
shielding and grounding:
• Connect LDT cable shields and drive output cable shields (all
shields at one end, only) to IFM terminal block SH terminals, and
connect the IFM terminal block GND terminal (51) to earth ground.
• Keep LDT signal cables far from motors or proportional amplifiers.
• Connect all of the following to earth ground:
– power supply cable shields (one end, only)
– LDT flange, frame, and machine
– I/O chassis
– AC ground
• Use shielded twisted pairs for all connections to inputs and outputs.
• Run shielded cables only in low-voltage conduit.
• Place the SLC-500 processor and I/O chassis in a suitable enclosure.
Publication

Important: To minimize the adverse effects of ground loops, you must
isolate power supply and signal commons from earth ground as follows:
1. Connect power supply commons to IFM Com terminal (50), and
LDT commons to LDT Com terminals of the IFM terminal block.
Be sure that they are isolated from earth ground.
2. Connect the cable shield of the servo or proportional amplifier
output cable to a zero potential terminal inside the amplifier.
3. Use bond wires that are equal in size to signal wires.
4. When practical, use one power supply to power only your LDTs.
Connecting Outputs to Output Devices
Note: Follow manufacturer recommendations for shielding the output
cables of the proportional amplifier. Typically, pulse-width modulated
outputs radiate electrical noise originating from the +24V dc power
supply, so isolate the shields of the amplifier output cable to a 0V dc
connection inside the proportional amplifier.
You have a choice of three configurations to match your hydraulics:
• proportional amplifier integrated with a proportional valve
• servo amplifier and variable-volume pump or servo valve
• Allen-Bradley 1305 Drive and hydraulic pump
You may use either of the following output voltage ranges:
• 0-10V dc for an Allen-Bradley 1305 Drive or variable-volume pump
• –10 to +10V dc for a proportional or servo amplifier
If using servo valves, you must convert the module’s output from
voltage to current.
Output Polarity
In most hydraulic systems, the actuator extends (with increasing
LDT counts) when a positive voltage is sent to the output. The
extend direction is defined as the direction that causes the LDT to
return increasing counts moving away from the head.
Publication
You can make these selections in the Config word that affect output:
• To generate a positive drive output (0-10V dc) regardless of move
direction, you can select Absolute Mode.
• To extend the actuator by sending a negative voltage to the
output, you can select Reverse Drive Mode.

subject in Help Topics.

Checking Out the Wiring and Grounding
Repeat this procedure to check out each of the four axis loops
connected to the IFM terminal block.
ATTENTION: Be sure to remove all power to the SLC processor,
LDT, valve and pump beforehand.
1. Disconnect the LDT connector at the head end.
2. Disconnect the connector to the IFM terminal block.
3. Turn ON the power supplies for the LDT and SLC processor, and
check the LDT connector and IFM terminal block for:
• +15V dc
• PS common
• –15V dc
4. Observe that the module’s fault LED indicates Green.
5. Verify continuity between IFM COM terminal (50) and each of:
• shield of the amplifier output cable to the valve
• output common on "15V dc PS that powers the LDT
• (–) terminal on +24V dc PS that powers the proportional amplifier
6. Verify NO continuity between drive output commons connected to
IFM terminals 3, 7, 11, 15 and earth ground.
Setting Up the Hydraulics
7. To minimize ground loops, verify that all cable shields are grounded
(at one end, only) to SH terminals of the IFM terminal block, and
that GND terminal (51) of the IFM is connected to earth ground.
1. Design for adequate pressure and volume. Hydraulic systems
must have enough pressure and fluid volume (accumulator) to move the
desired load the commanded distance and speed. Inadequate pressure
or volume will cause the axis to lag the target position as the controller
attempts to move the axis faster than the system can move. Consider
monitoring system pressure or providing a low-limit (approx. 80%)
pressure switch.
2. Avoid flexible hose. Use no flexible hose between the valve and
the cylinder being controlled. Flexible hose will swell and contract
as the valve opens and closes, causing oscillation and loss of control.
3. Mount valve and cylinder in correct orientation. To avoid
problems from entrapped air, mount the valve directly to the cylinder
and positioned above it. Mount pressure sensors beneath the cylinder.
4. Use linear valves with minimal overlap. If using proportional
valves, they should have less than 3% overlap and a linear (not
curvilinear) response. Nonlinear valves or valves with excessive
(20%) overlap may cause oscillation or hunting. We recommend
using servo valves or servo-quality proportional valves.

5. Avoid valves with a slow response (less than 60 Hz). Valves with
slow response cause the module to overcompensate for disturbances in
the motion of the system. Since the system does not respond immediately
to the control signal, the module continues to increase the drive signal.
By the time the system begins to respond to the error, the control signal
has become too large and the system overshoots. The module then
attempts to control in the opposite direction, but again overshoots. These
valves can cause the system to oscillate around the set point as the
module overshoots first in one direction, then the other.
Regarding the Interface
Module Terminal Block
(Cat. No. 1492-AIFMQS)
and Cable
We recommend that you use the Interface Module (IFM) terminal
block (Cat. No. 1492-AIFMQS) to connect module I/O and power.
It facilitates power supply, shield, and fuse connections.
It is required for CE certification.
The pre-wired cable that connects the IFM terminal block to the
module is available in standard sizes as indicated by its part number,
1492-ACABLExxxQ, where xxx indicates the length in meters:
length: xxx:
0.5 m 005
1.0 m 010
2.5 m 025
Important: Because the sytem was certified with a shorter cable,
you must re-certify the system if using the 2.5 m cable.
Publication 1492-5.1 describes the IFM terminal block and cables.
For information on the entire line of Allen-Bradley Interface
Modules and associated cables for wiring analog systems, refer to
publication 1492-2.15.

Setting Up Communication Between PC and Module
You must establish communication between Hydraulic Configurator
software on your PC and the module.
1. Connect your PC to the module with Allen-Bradley cable (cat. no.
1747-CP3): one end to a serial port on your PC such as COM1, the
other end to the 9-pin D-shell connector on the module.
Windows ’95 provides a virtual connection to the serial port without
any intervention unless that port is already used by another application.
Important: You may run RSLogix500 and Hydraulic Configurator
concurrently on your PC if you have both COM1 and COM2
available. If only one serial port is available, you may use the
Communication Interface Card (1784-KTx) for the connection
between PC and SLC processor.
2. Open the Hydraulic Configurator by running QsCfg.exe.
The main screen appears.
If you also get the message “No Motion Controller Detected,” then:
– check the1747-CP3 cable connection between PC and module
– match the software/hardware
COM ports (step 3.)
Otherwise, go to step 4.
3. Set the Hydraulic Configurator COM port to match your PC.
To do this, click T
the menu. Enter the
ools on the toolbar, then Monitor Options from
COM port number you used for your PC cable
connection to the module in step 1.
4. To verify communication with the module, observe that the Com:
window (screen bottom left) displays “Online“.
Important: You can run the Hydraulic Configurator offline to view
plots, stored data files, and access Help screens.
