ORIC® Piezo Stage Controller PDXC Chapter 3: Overview
Rev B, September 23, 2021 Page 3
Chapter 3 Overview
3.1. Introduction
The PDXC Piezo Stage Controller is designed to control our PD1(/M) Piezo Inertia Linear Translation Stage,
PDX1(/M) Piezo Inertia Linear Translation Stage with an Optical Encoder, and PDR1(/M) Piezo Inertia Rotation
Stage. It offers two channels of open-loop stage control (SMC outputs), and one channel of both open- and closed-
loop stage control (15-Pin D-SUB output). The user can easily switch between operations by turning the knob after
powering on the unit. It also supports remote PC control via the USB or RS-232 ports on the back panel, and a USB
mouse can be connected to the front panel for intuitive control. The product supports daisy-chain mode in which
several controllers work together tomove multiple stages at very low delay by inserting RJ-45 cables betweenthem.
The controller also supports external I/O control, including analog in and out, and trigger in and out signals. There
are several external trigger modes inside to support either single motion or conjunction motions, such as a raster
scan. For best convenience of control, the user can interact with the device by using the buttons and knob on the
front panel while observing the LCD display.
Figure 3.1 Outlook of PDXC Controller
Features
▪Stages with open- and closed-loop operation are supported
▪A modular linear amplifier paired with a high-power power supply outputs a peak current of 10 A to drive
the stage.
▪The high current coupled with the optimized waveforms stably drive the stage as fast as 20 mm/s.
▪Even at its highest speed, the optimized high-speed PID values allow the stage to move at ±2% speed
deviation in closed-loop mode.
▪High positioning resolution up to 10 nm.
▪With dynamic adjustment, the device stays at any precise position within a range of 10 nm in closed-loop
mode.
▪Low time delay between devices when in daisy-chain mode.
3.2 Operation Principle
The controller mainly consists of 2 PCB boards, the MCU board, and the power board. The MCU board generates
a sawtooth waveform (Figure 3.2.1) while the power board magnifies the amplitude signal. The waveform is then
exported to the 15-pin D-SUB connector or SMC connector on the front panel to drive the different stages.
The stage uses a piezo inertial drive motor, which consists of three main parts: a flexure-coupled piezo actuator, a
friction element, and a slider (as seen in Figure 3.2.2). During the "stick" part of a cycle, the piezo slowly expands
under the ramp voltage, pushing the friction element and the slider forward in unison. During the "slip" part, the
drive voltage drops rapidly and the piezo element returns to its starting length, with the friction element "slipping"

ORIC® Piezo Stage Controller PDXC Chapter 3: Overview
Page 4CTN015391-D02
backward. The slider does not move due to its inertia and the low coefficient of kinetic friction between the friction
element and the bottom surface of the slider. Figure 3.2.1 shows the piezo drive voltage during one "stick-slip"
cycle.
Repeating this cycle produces continuous forward travel of the slider. To travel in the reverse direction, the
opposite drive voltage pattern is required, resulting in rapid piezo expansion and slower piezo contraction, or "slip-
stick". During operation, the stage makes a high-pitched noise and may generate some heat. This is normal
behavior in the performance of the device and does not indicate a faulty condition.
Due to several factors that include the application conditions, piezo hysteresis, component variance, and the axial
load, the achieved step size will vary and is not repeatable. To help overcome this variance and accurately control
the stage movement, an external feedback system is added for closed-loop control of the feedback slider position
to controller.
Figure 3.2.1 Sawtooth Waveform Figure 3.2.2 Stick-Slip Movement Illustration
3.3 Stages Connection and Accessories
Figure 3.3.1 shows how the stages are connected to the PDXC controller. The two SMC connectors connect to
ORIC®Piezoelectric Inertia Drive Stages, i.e., PD1(/M). The DB15 connector connects with the ORIC®Piezoelectric
Inertia Drive Stages with Optical Encoders, i.e. PDX1(/M). Please note that the controller operates open- and
closed-loop stages separately under different operation modes. To switch operation modes, a power cycle is
required.

Chapter 4 Panel Operation
The PDXC Piezo Stage Controller can be operated in one of three ways:
1. From the front panel
2. Using the included software
3. Using the command set
This chapter will focus on the panel operation of PDXC Piezo Stage Controller.
4.1. Getting Started
Connect the controller with the stages according to the instructions in Chapter 0. Connect the power cord and then
power on the devices.
SHOCK WARNING
The maximum current output for the piezo stage is 10 A, and both the SMC and D-Sub connectors do
not support hot plugging. Plugging or unplugging the connector while the unit is powered on can cause
damage to the stage and/or controller.
After being powered on, allow the unit a few seconds to initialize. Once the initialization is done, the device will ask
user to choose between SMC output mode, which only supports open-loop stages, i.e., PD1(/M), and D-Sub output
mode, which supports stages with both open- and closed-loop operation, i.e. PDX1(/M). Move the cursor by turning
the knob on front panel and press the “ENTER” button to select the desired mode.
Figure 4.1 Output Mode Selection
Even without the user pressing the ENTER button, the device will enter its last operation mode after 3 seconds of
idle in the output selection screen. If the stage is connected via D-Sub connector,the device will automatically enter
D-Sub mode. Otherwise, the controller will enter SMC mode unless the user turns the knob or clicks the ENTER
button.
4.2. D-Sub Output Mode
Select “D-SUB” at the mode selection screen right after initialization to enter D-Sub output mode. In D-Sub output
mode, only one piezo stage is supported. There are encoders on those stages to provide accurate position and
velocity feedback thus both open-loop and closed-loop operations are possible.
In closed-loop mode, the encoder feedback signal for position and velocity are measured and compared to the set
value. A PID control loop automatically corrects the driving signal applied to the stages according to the error
between the measured position and velocity and the target position and velocity. Accurate positioning and velocity
control can be achieved in this mode.
In open-loop mode, only the feedback signal from the encoder is monitored. The stages are driven by a default
waveform according to preset configurations.
The main screen of the D-Sub output mode is shown below. HOMING is a necessary process for both open-loop
and closed-loop operations to be accurately executed. The main screen will show the message “NEED HOME
FIRST!” if users do not complete the HOMING operation after power cycles.

Rev B, September 23, 2021 Page 11
Figure 4.2 D-Sub Mode Main Screen
4.2.1. Move Stage in Closed-Loop Operation
In closed-loop mode, only the feedback signal from the encoder is monitored. The stages are driven by a default
waveform according to preset velocity or step size.
Similar to the operation of SMC output mode, to move the stages in open loop, turn the knob at the main screen of
the D-Sub menu.
Figure 4.3 Close-Loop Operation in D-Sub Output Mode Main Screen
Figure 4.4 Moving a Stage to a Target Position
When in the SMC output main screen, turn the knob to move the stages according to preset velocity (speed) and
step size. To change the velocity and step size setting, please refer to Section 4.2.2. Panel operation allows the
user to move only one stage at a time. Moving two stages simultaneously would require software or command line
operation.

the menu and follow the flow chart below.
Figure 4.5 Set Velocity in Closed-Loop Operation
4.2.3. Move Stage in Open-Loop Operation
In open- loop operation in D-Sub output mode, the position of the stage is still monitored by the encoder on stage,
but the measured signal will not participate in any feedback. The stage is driven by default waveforms according to
preset configurations.
When the stage is set to open-loop mode of the D-Sub output, turning the knob will move the stages according to
preset velocity (speed) and step size. To change the velocity and step size setting, please refer to Section 4.2.4.

4.2.7. Homing
Homing is a necessary process for closed-loop operation to be accurately executed. We recommend homing every
time the stage is switched to closed-loop mode from open loop operation, or after power cycles.
The homing process scans the stage across its entire travel range and looks for a “HOME” position to set as the
absolute reference position for the stage. All the stage movements are executed relative to that HOME position.
To execute the homing process, follow the flow chart below:

4.2.8. Encoder Calibration
Calibration is an essential operation that completes encoder set-up on a piezo inertial drive stage, with the optimum
incremental and reference mark signal settings stored in the readhead’s non-volatile memory. Each stage is already
calibrated before shipping out. Usually, the stage does not require recalibration often, but long-term operation,
shock, or mishandling could trigger the need for recalibration to retain accurate operation. It is a process that can
be performed by users.
The device will query if calibration is needed upon each power recycle if D-Sub is active. The user may need to do
calibration if the position reported is not accurate or when the homing process has failed multiple times.
When the stage connected to the PDXC requires recalibration, the below screen will appear on the LCD screen
automatically.

Press ENTER button if this screen shows up, which will lead to the calibration routine. Follow the steps below to
complete the calibration.

Step 2: The user moves the stage manually to its half range, starting from the middle position, toward either end of
the travel range, back and forth, several times with very low speed (<10 mm/s).
Figure 4.13 Step 2 of Calibration
Step 3: The user moves the stage manually to its full range, from one end to the other, repeating this operation
several times before going to Step 4.
Figure 4.14 Step 3 of Calibration
Step 4: Similar to Step 1, wait 5 seconds until the calibration is finally successful.
Figure 4.15 Step 4 of Calibration
4.3. SMC Output Mode
Select “SMC” at the mode selection screen right after initialization to enter SMC output mode. In SMC output mode,
only open-loop stages are supported. There are no encoders on those stages thus no position and speed feedback
