Ethernet Connector
Dual connector master/slave
configuration. Used to communicate
with an external computer.
USB Connector Type B
Used to communicate with an
external computer.
Controller synchronizing signals and
RS-232 NanoScan-Z connection. For RS-
232 connection, connect a plug-to-plug
9 pin gender changer/adaptor to the
controller, and then
connect to the PC’s
RS-232 port using a
9 pin serial cable.
Power Indicator LED
Indicates the power status and functionality of the
product. RED steady = Controller configuring/not
ready (can take up to 30 seconds). GREEN steady =
Controller powered and ready for operation
CLOSED INDICATOR LED
Indicates the status of the stage control Loop
OFF = Stage NOT connected
ORANGE = Stage settings being loaded on connection
RED = Controller operating in OPEN loop mode
GREEN = Controller operating in CLOSED loop mode
YELLOW = Controller servo output frozen
COMS Indicator LED
Indicates the state of the controller communications with
the connected computer. Not lit = No communications
taking place. GREEN lit or flashing =
Communications are taking place
IN POS Indicator LED
Indicates the status of the stage position in
CLOSED loop mode. ORANGE = Stage settings
being loaded on connection. OFF = Stage has not
reached the desired position. GREEN = Stage has
reached the desired position (within specified limits)
Nano Mechanism Connector – connect the OP400 to
this position. This provides the stage piezo HV supply,
power for calibration EEPROM and measuring
signals for capacitive sensor operation. NOTE High
Voltage present on connector – up to 160VDC

TURNING ON YOUR SYSTEM
1. Once the stage is mounted, connect stage to the controller ensuring that the connector screws are tightened to the controller lock posts. The
stage must be mounted to a flat surface before being powered. On powerup, the controller will always sweep the stage across its range to
carry out auto-calibration. It is important to ensure that slides, lenses and other equipment are fitted after the auto-calibration (after
powerup).
2. Connect Power to controller and USB interface to the PC.
3. Switch ON controller using switch on rear panel. After approx. 30 seconds, the relevant stage channel should show two green lights (Closed
and IN-POS). This indicates the stage is operating in the CLOSED loop mode and IN-POS LED indicates stage has reached position within a
pre-defined band.
4. The analogue input and POS MON output is 0V to +10V giving a scale factor of 40µ/volt. The analogue input is enabled by
default. The Scale Factor is in microns per volt. 50 microns per volt for the OP400.
5. The system has 8 memory positions for PID settling (accessible via the USB interface). The system has been shipped with
optimized settings for different objective loads, resolution and step settle requirements. The default setting has been optimized for loads from
150g to 500g. To change to the other settings it is necessary to connect to a computer, the next section demonstrates how to change to other
settings. Do not change settings too fast for load used or damage to the unit may occur. If during operation the stage begins to vibrate (resonate)
power down the system quickly. It is likely the stage is being used outside the limits of the current setup. If a large load mass has just been
added either remove it or select a slower tuning present that will support that load. Ensure the stage and sample is bolted down fully.
Remove input commands. If still vibrating please contact Prior for assistance.
