2.2 Connect the drive to PC using Ethernet
Dual port RJ-45 connectors of the STF-D/IP Drive accept standard Ethernet cables and are
categorized as 100BASE-TX(100 Mb/s) ports. CAT5 or CAT5e (or higher) cables should be used.
Connecting the drive to PC requires three steps:
•Physically connect the drive to your network (or directly to the PC)
•Set the drive’s IP address
•Set the appropriate networking properties on your PC.
Note: the following pages are an excerpt from the “eSCL Communication Reference
Guide”.
For more information, please read the rest of the guide.
Addresses, Subnets, and Ports
Every device on an Ethernet network must have a unique IP address. In order for two devices to
communicate with each other, they must both be connected to the network and they must have
IP addresses that are on the same subnet.A subnet is a logical division of a larger network.
Members of one subnet are generally not able to communicate with members of another unless
they are connected through special network equipment (e.g. router). Subnets are defined by the
choices of IP addresses and subnet masks.
If you want to know the IP address and subnet mask of your PC, select Start…All Programs…
Accessories…Command Prompt. Then type “ipconfig”and press Enter. You should see
something like this:
If your PC’s subnet mask is set to 255.255.255.0, a common setting known as a Class C subnet
mask, then your machine can only talk to another network device whose IP address matches
yours in the rst three octets. (The numbers between the dots in an IP address are called octets.)
For example, if your PC is on a Class C subnet and has an IP address of 192.168.0.20, it can talk
to a device at 192.168.0.40, but not one at 192.168.1.40. If you change your subnet mask to
255.255.0.0 (Class B) you can talk to any device whose rst two octets match yours. Be sure to
ask your system administrator before doing this. Your network may be segmented for a reason.
Your drive includes a 16 position rotary switch for setting its IP address. The factory default
address for each switch setting is shown in the table on the next page.
Settings 1 through E can be changed using the STF Congurator software. Setting 0 is always
“10.10.10.10”, the universal recovery address. If someone were to change the other settings and
not write it down or tell anyone (I’m not naming names here, but you know who I’m talking about)
then you will not be able to communicate with your drive. The only way to “recover” it is to use the
universal recovery address.

9Rev. 1.0
11/28/2017
STF-D/IP Hardware Manual
400-820-9661
Setting F is “DHCP”, which commands the drive to get an IP address from a DHCP server on
the network. The IP address automatically assigned by the DHCP server may be “dynamic”
or “static”depending on how the administrator has configured DHCP. The DHCP setting is
reserved for advanced users.
Your PC, or any other device that you use to communicate with the drive, will also have a unique
address.
On the drive, switch settings 1 through E use the standard class B subnet mask (i.e.
“255.255.0.0”). The mask for the universal recovery address is the standard class A (i.e.
“255.0.0.0”).
One of the great features of Ethernet is the ability for many applications to share the network at
the same time.
Ports are used to direct traffic to the right application once it gets to the right IP address. The UDP
eSCL port in our drives is 7775. To send and receive commands using TCP, use port number
7776. You’ll need to know this when you begin to write your own application. You will also need
to choose an open (unused) port number for your application. Our drive doesn’t care what that
is; when the first command is sent to the drive, the drive will make note of the IP address and port
number from which it originated and direct any responses there. The drive will also refuse any
traffic from other IP addresses that is headed for the eSCL port. The first application to talk to a
drive “owns”the drive. This lock is only reset when the drive powers down.
If you need help choosing a port number for your application, you can find a list of commonly used
port numbers at http://www.iana.org/assignments/port-numbers.
One final note: Ethernet communication can use one or both of two “transport protocols”: UDP
and TCP. eSCL commands can be sent and received using either protocol. UDP is simpler and
more efficient than TCP, but TCP is more reliable on large or very busy networks where UDP
packets might occasionally be dropped.

Option 1: Connect a Drive to Your Local Area Network
If you have a spare port on a switch or router and if you are able to set your drive to an IP address
that is compatible with your network, and not used by anything else, this is a simple way to get
connected. This technique also allows you to connect multiple drives to your PC. If you are on a
corporate network, please check with your system administrator before connecting anything new
to the network. He or she should be able assign you a suitable address and help you get going.
If you are not sure which addresses are already used on your network, you can find out using
“Angry IP scanner”, which can be downloaded free from http://www.angryip.org/w/Download.
But be careful: an address might appear to be unused because a computer or other device is
currently turned off.And many networks use dynamic addressing where a DHCP server assigns
addresses “on demand”. The address you choose for your drive might get assigned to
something else by the DHCP server at another time.
Once you’ve chosen an appropriate IP address for your drive, set the rotary switch according the
address table above. If none of the default addresses are acceptable for your network, you can
enter a new table of IP addresses using Configurator. If your network uses addresses starting with
192.168.0, the most common subnet, you will want to choose an address from switch settings 4
through E. Another common subnet is 192.168.1. If your network uses addresses in this range, the
compatible default selections are 1, 2 and 3.
If your PC address is not in one of the above private subnets, you will have to change your subnet
mask to 255.255.0.0 in order to talk to your drive. To change your subnet mask:
1. On Windows XP, right click on “My Network Places”and select properties. On Windows 7,
click Computer.
Scroll down the left pane until you see “Network”. Right click and select properties. Select
“Change adapter settings”
2. You should see an icon for your network interface card (NIC). Right click and select properties.
3. Scroll down until you see “Internet Properties (TCP/IP)”. Select this item and click the
Properties button. On Windows 7 and Vista, look for “(TCP/IPv4)”
4. If the option “Obtain an IP address automatically”is selected, your PC is getting an IP
address and a subnet mask from the DHCP server. Please cancel this dialog and proceed to
the next section of this manual: “Using DHCP”.
5. If the option “Use the following IP address”is selected, life is good. Change the subnet
mask to“255.255.0.0”and click OK.

Using DCHP
If you want to use your drive on a network where all or most of the devices use dynamic IP
addresses supplied by a DHCP server, set the rotary switch to “F”. When the drive is connected
to the network and powered on, it will obtain an IP address and a subnet mask from the server
that is compatible with your PC. The only catch is that you won’t know what address the server
assigns to your drive. ST Configurator can find your drive using the Drive Discovery feature, as
long as your network isn’t too large. With the drive connected to the network and powered on,
select Drive Discovery from the Drive menu.
You will see a dialog such as this:
Normally, Drive Discovery will only detect one network interface card (NIC), and will select it
automatically. If you are using a laptop and have both wireless and wired network connections, a
second NIC may appear.
Please select the NIC that you use to connect to the network to which you’ve connected your
drive. Then click OK. Drive Discovery will notify you as soon as it has detected a drive.
If you think this is the correct drive, click Yes. If you’re not sure, click Not Sure and Drive
Discovery will look for additional drives on your network. Once you’ve told Drive Discovery which
drive is yours, it will automatically enter that drive’s IP address in the IP address text box so that
you are ready to communicate.

Option 2: Connect a Drive Directly to Your PC
It doesn’t get much simpler than this:
1. Connect one end of a CAT5 Ethernet cable into the LAN card (NIC) on your PC and the other
into the drive.
You don’t need a special “crossover cable”; the drive will automatically detect the direct
connection and make the necessary physical layer changes.
2. Set the IP address on the drive to “10.10.10.10”by setting the rotary switch at “0”.
3. To set the IP address of your PC:
a. On Windows XP, right click on “My Network Places”and select properties.
b. On Windows 7, click Computer. Scroll down the left pane until you see “Network”. Right
click and select properties. Select “Change adapter settings”
4. You should see an icon for your network interface card (NIC). Right click and select properties:
a. Scroll down until you see “Internet Properties (TCP/IP)”. Select this item and click the
Properties button.
b. On Windows 7 and Vista, look for “(TCP/IPv4)”
5. Select the option “Use the following IP address”. Then enter the address “10.10.10.11”.
This will give your PC an IP address that is on the same subnet as the drive. Windows will
know to direct any traffic intended for the drive’s IP address to this interface card.
6. Next, enter the subnet mask as “255.255.255.0”.
7. Be sure to leave “Default gateway”blank. This will prevent your PC from looking for a router
on this subnet.
8. Because you are connected directly to the drive, anytime the drive is not powered on, your PC
will annoy you with a small message bubble in the corner of your screen saying “The network
cable is unplugged.”

400-820-9661
Option 3: Use Two Network Interface Cards (NICs)
This technique allows you to keep your PC connected to your LAN, but keeps the drive off the
LAN, prevent¬ing possible IP conflicts or excessive traffic.
1. 1.If you use a desktop PC and have a spare card slot, install a second NIC and connect it
directly to the drive using a CAT5 cable. You don’t need a special “crossover cable”; the
drive will automatically detect the direct connection and make the necessary physical layer
changes.
2. If you use a laptop and only connect to your LAN using wireless networking, you can use the
built-in RJ45 Ethernet connection as your second NIC.
3. Set the IP address on the drive to “10.10.10.10”by setting the rotary switch at “0”.
4. To set the IP address of the second NIC:
a. On Windows XP, right click on “My Network Places”and select properties.
b. On Windows 7, click Computer. Scroll down the left pane until you see “Network”. Right
click and select properties. Select “Change adapter settings”
5. You should see an icon for your newly instated NIC. Right click again and select properties.
a. Scroll down until you see “Internet Properties (TCP/IP)”. Select this item and click the
Properties button.
b. On Windows 7 and Vista, look for “(TCP/IPv4)”
6. Select the option “Use the following IP address”. Then enter the address “10.10.10.11”.
This will give your PC an IP address that is on the same subnet as the drive. Windows will
know to direct any traffic intended for the drive’s IP address to this interface card.
7. Next, enter the subnet mask as “255.255.255.0”. Be sure to leave “Default gateway”
blank. This will prevent your PC from looking for a router on this subnet.
8. Because you are connected directly to the drive, anytime the drive is not powered on your PC
will annoy you with a small message bubble in the corner of your screen saying “The network
cable is unplugged.”

2.4 Choosing A Power Supply
The main considerations when choosing a power supply are the voltage and current requirements
of the application.
2.4.1 Voltage
The STF drive and motor is designed to give optimum performance between 24~48 Volts
DC. Choosing the voltage depends on the performance needed and diver/motor heating that
acceptable and/or does not cause a drive over-temperature. Higher voltage will give higher speed
performance, but will cause the drive to produce higher temperatures. Using power supplies with
voltage outputs that are near the drive maximum may significantly reduce the operational duty
cycle.
The STF03/06 drive extended range of operation can be as low as 11VDC minimum to as high
as 53VDC maximum(18-53VDC for STF05 Drives, and 18-75VDC for STF10 Drives). When
operation below 11VDC, the STF03/06 series will work unstable. The supply input cannot go blow
11VDC for reliable operation, otherwise under voltage alarm will be triggered. STF03/06 drive will
stop working when this alarm is triggered.
STF03/05/06
If a regulated power supply is used, and that is near the driver maximum voltage of 53VDC ,a
voltage clamp may be required to prevent the voltage over 53VDC which will occurs a overvoltage
fault. When using an unregulated power supply, make sure the no-load voltage of the supply does
not exceed the maximum input voltage 53VDC.
STF10
If a regulated power supply is used, and that is near the driver maximum voltage of 75VDC ,a
voltage clamp may be required to prevent the voltage over 75VDC which will occurs a overvoltage
fault. When using an unregulated power supply, make sure the no-load voltage of the supply does
not exceed the maximum input voltage 75VDC.
2.4.2 Current
When STF drives work with different motors, the recommended power supply output current
capacity under different supply voltage is shown in below table. The STF drive power supply
current is lower than the the winding currents because it uses switching amplifiers to convert a
high voltage and low current into low voltage and high current. The more power supply voltage
exceeds the motor voltage,the less current will be required from the power supply.
It is important to note that the current draw is significantly different at higher speeds depending
on the torque load to the motor. Estimating how much current is necessary may require a good
analysis of the load to the motor.

3.1.2 X5, X6, X7 and X8 Digital Inputs
X5, X6, X7 and X8: optically isolated, single-ended, 5-24VDC for high level voltage, minimum
pulse width 100μs, maximum pulse frequency 5KHz
•X5 can be used as motor enable input or general purpose input.
•X6 can be used as alarm reset input or general purpose input.
•X7 can be used as general purpose input or touch Probe 1 trigger input.
•X8 can be used as general purpose input or touch Probe 2 trigger input.
Because the input is an optically isolated circuit, a 5-24V power supply is needed. For example,
you can use the power supply of the PLC when you are using a PLC control system, but if you
want to connect a relay or mechanical switch to the input , you must need a power supply.
XCOM is an electronics term for a single-ended signal connection to a common voltage. If you are
using a sourcing (PNP) input signals, you need to connect XCOM to the ground (power supply
-), if you are using a sinking(NPN) input signals ,the XCOM need to be connected to the power
supply +.
Use STF Congurator software for X5, X6, X7 and X8 function configuration.
