Chapter 1

Setup

Overview

The high-power Halogen Light Source with attenuator and shutter uses a 20-watt bulb for appli cations
requiring la rge-diameter optical fibers, or fiber and probe bundles. The attenuator and shutter can be
controlled by a series of ASCII commands issued by a host computer via RS-232.

Setting Up the HL-2000-HP-232 Light Source

Unpacking the Light Source

► Procedure

1. Unpack your new equipment carefully. Dropping this instrument can cause permanent damage.

000-10000-140-02-201307 1

1: Setup

2. Inspect th e outside of the instrument and make sure that there is no damage. Do not use the

instrument if damage is present. Contact your dealer for repair or replacement information, if
necessary.

3. Use this instrument in a clean laboratory environment.

Package Contents

Your package should contain the following:

 One HL-2000-HP-232 Light Source
 One serial cable
 One 24 VDC 1,2A power supply
 HL-2000-HP-232 test software

In addition, you need an optical fiber (1000 μm diameter fiber is recommended).

Set-Up

Use the following procedure and diagrams to set up your light source.

2 000-10000-140-02-201307

1: Setup

► Procedure

1. Plug the power sup p ly int o a wall ou tl et.

2. Plug the other end of the power supply cable into the socket of the light source.

3. Plug the serial cable (included) into the light source connector, and the other end into the COM

port on your PC.

4. Connect the SMA connector of your fiber optic cable to the SMA plu gs.

5. Turn on the Halogen lamp using the power switch on the front of the light source. The shutter

opens and the lamp flashes once.

Notes

The light can only be turned on via RS232 (see ).

To test the l ight source, u se the HL-2000-HP-232 test software included with your
equipment.

Operation

Optimizing the Optical Power Out put

The HL-2000-HP-232 is adjusted at the factory to provide maximum power into a 200µm fiber. If a lower
optical power is required or a different fiber (bundle) diameter is used, you can adjust the optical power of
the unit.

Procedure

►

Follow the steps below to adjust the optical power of the HL-2000-HP-232 Light Source:

1. Connect a fiber opt ic spe ctr o met er or an opt ic al po we r met e r to a fiber, an d th en con ne ct the other

end of the fiber to the HL-2000-HP-232’s SMA plug.

2. Loosen the blocking screw with the provided 1.3mm Allen wrench.

000-10000-140-02-201307 5

2: Operation

3. Shift the SMA socket to optimize the optic al power of the light source.

4. Tighten the blocking screw to secure the SMA socket position.

Appendix A

ASCII Commands

In serial communications mode, the motion controller is controlled via a series of ASCII instructions
issued by a host computer.

Motion-Related Commands

Command Function Description Example

M Initiate Motion Receipt of the "M" Move command initiates

motion using the values presently loaded to
determine the profile characteristics.

LA Load Absolute Position Allows programming of the desired target

position relative to the present zero or "home"
position.

LR Load Relative Position Allows programming of the desired tar ge t

position relative to the present position.

SP Load Command

Velocity

AC Load Command

Acceleration

V Select Velocity Mode Execution of this command causes the

This parameter should be loaded with the
desired maximum profile velocity in position
mode. This value should be selected to not
exceed the capabilities of the mechanical
system. Additionally, this command sets the
maximum velocity value in "velocity mode".

This parameter determines the acceleration and
deceleration rate to be calculated by the profiler
during execution. Argument in rpm/s

(Allowed value: 0 to 20000)

mode. The motor will ramp the selected velocity
at the rate defined by the AC parameter.

A: ASCII Commands

Command Function Description Example

DI Disable Drive Execution of this command disables the drive

electronics and removes all current from the
motor

EN Enable Drive This instruction enables the drive electronics

and allows the servo controller to become
active, providing motor current as required.

LL Load Position Range

Limits

The range limit mechanism provides an
additional layer of protection. Both positive and
negative range limits are determined
independently using the sign of the limit
parameter. If the controller receives an
instruction from the host to move to a position
that is not within the range limit window, it will
stop at the set limit position.

DI

LL 2000000

LL -5000000

Configuration-Related Commands

Command Function Description Example

POR Set Proportional Loop

Gain

The proportional gain determines the system's
proportional response to a given amount of
positional error. Increasing this parameter
provides a tighter and more dynamically
responsive system. (Allowed value 0 – 255)

POR 20

I Set Integral Loop Gain Unlike the proportional gain, where the

response remains constant if there is no
change in error, the integral term continues to
increase the effects of its response until it
becomes effective. This parameter determines
the rate of change of this response.

(Allowed value 0 – 255)

A: ASCII Commands

Command Function Description Example

DCE Delayed Current Error This command sets the delay between current

limit condition and setting the Fault-Status
(Fault-Pin and Fault-Bit for the GFS­Command). The DCE argument is in
milliseconds.

SOR Source For Velocity This command defines the source for the

velocity of the motor.
SOR 0 defines that commanded velocity will

come from a serial command message using
RS232.

SOR 1 defines that the velocity value will be
an analog input voltage of +/-10 VDC at the
analog input. SOR 2 defines that the velocity
value will be a PWM signal at the analog input.
Note that the SP value dictates the Maximum
Velocity reached for the Maximum PWM signal
(SOR2) and the Maximum Velocity for 10 V at
the analog input (SOR1).

EEPSAV Save To EEPROM This command saves the current parameters

and configurations to EEPROM. The saved
parameters are recalled during power up so
that the motor is configured for use
immediately. After saving all configuration
parameters, a serial message "EEPROM
writing done" will be sent from the controller.

DCE 200

SOR 1

EEPSAV

NP Notify Position This command tells the motion controller to

send a "p" message when a particular position
is reached. In the example above, when 10,00 0
is reached a "p" message will be sent from the
controller.

NP 10000

External Limit Switch Configurati on Commands

Command Function Description Example

HA Arm the "HOME" input This command is used to arm the Home Arming

mode. It is used with the external limit or
reference switch to define the home position
(the Analog input serves as this digital input as
well).

000-10000-140-02-201307 11

HA 1

A: ASCII Commands

Command Function Description Example

HL Home Limit Action This command is used to set the action that

occurs when the limit switch is activated. If HL
is set to 0, the motor will continue to run after
switch activation but will send an "h" message
signifying home switch was triggered. If HL is
set to 1, the motor will stop immediately after
switch activation.

HN Hard Notify If HN is set to 1, it configures the motion

controller to send a serial message "h" once the
external limit switch is triggered.

HP Define External Switch

Polarity

HS External Switch Status This command returns the state of the limit

This command defines the activation edge of
the external switch. If HP is 0 a falling edge at
the external limit switch is valid. If HP is 1 a
rising edge occurs actions due to HL, HN and
HA-commands.

switch. If the limit switch was active and an HS
request is sent, the controller will return a 1. If
the limit switch was not active since a HL, HN
or HA-command was sent an HS request will
return a 0 to the host.
