SMC100CC & SMC100PP Single-Axis Motion Controller/Driver for DC or Stepper Motor
2.0 System Overview
2.1 General Description
The SMC100CC/PP is a single axis motion controller/driver for DC servo or stepper
motors up to 48 VDC at 1.5 A rms. It provides a very compact and low-cost solution for
driving a variety of Newport and other manufacturers motorized stages from a PC or
from the optional SMC-RC remote control.
Communication with the SMC100CC/PP is achieved via a RS-232-C, or from a USB
port using the external adapter SMC-USB (requires Windows™ operating system). A
Windows™ based software supports all configurations and enables basic motion.
Advanced application programming is simplified by an ASCII command interface and a
set of two letter mnemonic commands.
When used with Newport ESP enhanced positioners, the SMC100CC/PP will detect the
connected product automatically and provides easy configuration using the supplied
Windows-based utility software. This exclusive Newport feature reduces configuration
time and provides the best protection of your equipment from any accidental damages.
Up to 31 controllers can be networked through the internal RS-485 communication link.
This internal multi-drop full-duplex serial link simplifies communication to several
units, without the need for sending “address selection commands”. This results in
enhanced multi-axes management with improved program readability and faster
communication compared to alternative systems based on a RS-232-C chain. The
typical execution time for a tell position command is only about 10 ms for the first
controller and only about 16 ms for the other controllers. The SMC100CC/PP also
features advanced “multi-axes” commands such as “Stop all” or “start a motion of all
axes” and performs at a 57600 bauds rate communication speed. Furthermore, for an
efficient process control, the SMC100CC/PP features dedicated digital outputs for "In
Motion" and for "Not referenced".

SMC100CC & SMC100PP Single-Axis Motion Controller/Driver for DC or Stepper Motor
3.0 Getting Started
This section guides the user through the proper set-up of the SMC100CC/PP motion
control system. When using the SMC100CC/PP controller ONLY in local control with
the SMC-RC keypad and NOT from a computer, you can skip this section and continue
reading in chapter 4.0, SMC100CC/PP with SMC-RC keypad. If not already done,
carefully unpack and visually inspect the controllers and the stages for any damage.
Place all components on a flat and clean surface.
CAUTION
No cables should be connected to the controller at this point!
First, the controller must be configured properly. When using several SMC100CC/PP
controllers from the same COM port through the internal RS-485 communication link,
an individual address must be set for each controller. Then, each controller must be
configured to the connected stage. For both steps, the software supplied with the
SMC100CC/PP is used.

SMC100CC & SMC100PP Single-Axis Motion Controller/Driver for DC or Stepper Motor
3.2 Communication to a Single SMC100CC/PP
Set the dip switches on the SMC100CC/PP to FIRST:
Connect the SMC100CC/PP to the RS-232 or to the USB port of your PC. Connect your
stage to the SMC100CC/PP (MOTOR connector). Connect the power supply. The LED
on the SMC100CC/PP turns RED.
3.3 Communication to Several SMC100CC/PP
When using several SMC100CC/PP controllers through the internal RS-485
communication link, you need to follow specific steps to be successful:
1. Apply individual addresses to each controller.
2. Connect all elements of the system together.
3. Configure each controller to drive the connected stage.
3.3.1 Controller Address Setting
The first thing to do is applying an individual address to each SMC100CC/PP
controller.
The address of the FIRST controller connected through RS-232-C remains the address
number 1. You don’t need to do anything with this controller. For addressing the other
controllers do the following:
Set the dip switches of ALL SMC100CC/PP to FIRST (see graphic below).
Connect ONE, and only one, SMC100CC/PP to the RS-232-C or to the USB port of
your PC. It is not needed to connect any stage to the controller. Connect the power
supply. The LED turns RED.
Set an address with the SMC100 applet GUI and select “Address” tab. It is
recommended to note down the address of the controller somewhere. For example, use
the stickers supplied with the SMC100CC/PP.
Now disconnect this controller from your PC and connect the next one instead. Select a
new, not yet allocated address and press the “Set” button again. Proceed the same with
all other controllers.
3.3.2 Building the System
When the addresses of all controllers are set, you can build your system.
Pull out all cables from all controllers. Set the dip switches of the controller with the
address number 1 as FIRST. Set the dip switches of the other controllers, except one, as
OTHERS, and set the dip switches of one controller as LAST. When you have only two
controllers, one has to be set as FIRST (the one with the address number 1), and the
other one as LAST. See below graphic for illustration.
Connect the SMC100CC/PP configured as FIRST to the RS-232-C port or to the USB
port of your PC. Connect a RS-485 network cable to the RS-485 OUT of the FIRST
controller and to the RS-485 IN of the next controller. Proceed the same with all other
controllers. When done, you can check your system:
EDH0206En2042 – 04/16 10

SMC100CC & SMC100PP Single-Axis Motion Controller/Driver for DC or Stepper Motor
•The controller configured as FIRST should have the RS-232-C cable connected. It
has the address number 1.
•All controllers configured as OTHERS should have one RS-485 network cable
connected to the RS-485 IN and another one to the RS-485 OUT.
•The controller connected as LAST should have one RS-485 network cable
connected to the RS-485 IN.
Connect your stages to the SMC100CC/PP’s (MOTOR connector). Connect your
SMC100CC/PP’s to power.
The SMC100CC/PP allows chaining power from one SMC100CC/PP to another one
using the SMC-PSC0.2 cable supplied with the controller. But the total power
consumption of all stages connected to the same power supply should not exceed 80 W.
The maximum power consumption of each Newport stage is listed in the Newport
catalog and on the Newport web site. In case of questions, contact Newport.
An example: The maximum power consumption of a VP-25XA is 48 W. The maximum
power consumption of an LTA-HS is 6 W. So it is possible to connect one VP-25XA
and up to 5 LTA-HS to the same power supply. But it is not possible to connect two
VP-25XA to the same power supply.
When done, your configuration should look as follow:
3.3.3 Configuring the Controller
Start the SMC100 Applet GUI and go to the “Parameters” tab.
When using the SMC100CC/PP with Newport ESP compatible stages (see label on the
stage), press “Download parameters from SmartStage”.
Start with the controller address 1. Press “Download parameters from SmartStage”.
Select the next available controller address and press “Download parameters from
SmartStage” again. Proceed the same with all other controllers.
When done, your system is configured and ready to use.
Using the SMC100CC/PP with non Newport ESP compatible stages or changing
the default values
When using the SMC100CC/PP with non Newport ESP compatible stages, you need to
enter the stage parameters manually in the Parameters tab. In the “Parameters” page you
can also change the configuration parameters stored in the controller. But it is not
recommended doing this unless you are an experienced user. For further information
about the meaning of the different parameters, please refer to the explanations at the
corresponding two letter commands (see command names in brackets) in section 6.5.
11 EDH0206En2042 – 04/16

SMC100CC & SMC100PP Single-Axis Motion Controller/Driver for DC or Stepper Motor
4.0 Default Speed Setting Control for Newport Stepper Stages
(only available for SMC100PP controller)
Due to some technical reasons, all Newport stepper stages will be set to be driven at
reduced speed with the SMC100PP controller (Reduced speed = Nominal speed / 2.5).
In order to check which stages can be driven at reduced speed or full speed, please refer
to the Newport web site (SMC100PP web page).
For example, an URSPP stage with a max speed of 40 °/s will be driven with a max
speed of 16 °/s when controlled by the SMC100PP controller.
For stages than can be driven at full speed (please refer to the Newport web site to get
the list), the defaut speed setting can be increased by the user to get the full nominal
speed.
4.1 Irms Current Setting for SMC100PP Controller
The connection type of a stepper motor can be bipolar (full winding) or unipolar (half
winding), but the SMC100PP controller always controls the stepper motor in the full
winding control mode. So the Irms current in each case must be different each from
other.
In the case of a unipolar motor, if the motor resistance (controlled in half winding) is R,
so the same motor resistance controlled in full winding is 2R.
For the same power (and the same thermal dissipation) in all two cases, we must have:
R.Ihalf2= 2R.Ifull2
(1)
Here: Ihalf is the motor current in the case of half winding control (this is also Asmart:
value found in the stage smart EPROM memory).
Ifull is the motor current in the case of full winding control.
From (1) we have:
Ifull = Ihalf / √2
(2)
So in the case of a unipolar motor controlled in full winding mode (SMC100PP), the
motor must not be controlled with the Asmart value, but Asmart / √2.
