Introduction

Thank you for selecting an Applied Motion Products motion controller. We hope our dedication to performance, quality and economy will make your motion control project successful. If there’s anything we can do to improve our products or help you use them better, please call or fax. We’d like to hear from you. Our phone number is

(800) 525-1609 or you can reach us by fax at (831) 761–6544.

Features

• Includes easy to use Windows set up and programming software

• In Router Mode, allows PC to control up to 8 motion control axes from one serial port, using SiNet Command Language (SCL).

• In Stored Program Mode, the hub is programmed with your PC and our easy to use SiNet Hub Programmer™ software, then runs stand alone, making the PC port available for a Man Machine Interface (MMI).

• Serial interface cable included.

• Works with any combination of Applied Motion Si™ indexer-drives: Si3540,

Si5580, Si4500, 3540i or 7080i.

• Also can be used with the Si-100 indexer, which provides step and direction signals compatible with a wide range of step motor and servo motor drives.

• Uses modular telephone line cords for all connections for low cost, reliable and easy wiring.

• No power supply required. The Hub 8 is powered by the drive connected to port 1.

• The address of each drive is set automatically by connecting it to a port, making installation and field service fast and simple.

• Built-in mounting flanges make installation easy.

• Front panel LEDs tell you if the hub has power, and whether it is receiving commands from the PC.

3540i: runs on 12 - 42 VDC, 3.5A/phase, 2000 - 50800 steps/rev

Si-100: indexer only, runs on 120/240VAC, provides industry standard step and direction signals to a wide range of step motor and servo motor drives

-2host “4R” (assuming the drive is “ready.” If it’s moving, you’ll see the response “4M”.) This is helpful if you send a global status request, since all drives will respond at the same time.

Programming - Stored Program Mode

In this mode, a multi-axis motion control program is stored inside the hub, and the hub operates without the PC. The PC is used to develop and test your program with the aid of our

SiNet Hub Programmer™ software.

Please refer to the SiNet Hub Programmer™ Software Manual when installing the software and developing programs.

Programming - Router Mode

When operated in router mode, the Hub-8 is a motion control network router. It transfers commands from your PC’s serial port to individual Si™ drives (up to 8) , and processes responses from the drives.

In router mode, the drives and hub are commanded using Si Command Language (SCL).

The Si Command Language is explained in the latest copy of the SCL Manual, which is included on the CD that ships with the hub. You can also get it from our web site at www.applied-motion.com.

You can use one of the cables that comes with the drives to connect the Hub-8 to your PC.

Ordinary telephone cables are used to connect the hub to the drives. At power up, the hub operates at 9600 baud, 8 data bits, one stop bit, no parity. There is no hardware handshaking. The BR (bit rate) command can be used to increase the communication speed.

you have a drive connected to port #1 You can apply power to all the drives at the same time. However, you may want to power up the drives “sequentially” to balance the load on

If you do not power up all the drives together , make sure you apply

The Hub-8 has two status LEDs marked COMM and POWER. If you have a drive connected to port #1 and that drive has power, then the POWER LED on the Hub-8 should light up.

The COMM LED will flash each time a command is sent from the PC to the Hub-8. You can use our SCL Setup Utility to test the Hub-8, and to get familiar with SCL commands. The

SCL Setup Utility is shipped with the hub. To use the hub in router mode, you’ll

need to set the “power up mode” to “router only.” The SCL Setup Utility allows you to control the power up mode. Simply connect the hub to your PC, open the SCL Setup

Utility, then apply power to the hub. A “Hub Power Up Mode...” button will appear. Click on it.

The addressing scheme is simple. If you want to send a Feed to Length command to the drive connected to port #1, send the hub the ascii string “1FL” followed by a carriage return

(ascii 13). If you omit the address character, the command is “global” and will be sent to all eight drives. That is useful is you want to send the same parameter (accel rate, for example) to all the drives.

If you ask a drive for status information, the hub will append an address character to the drive’s response. For example, sending “4RS” to the hub will result in the hub sending the

Getting Started

The SiNet™ Hub 8 can be used two different ways. You must choose based on your application.

Stored Program Mode SiNet Hub Programmer™ software on your PC, and point and click your way to a completed program. Once you’re done preparing and testing your program, it stays inside the hub and runs without the PC.

Your program not only controls up to 8 motion control axes, it can also interact with an operator using our Man Machine Interface (MMI). The MMI lets the operator make decisions, choose operations from a menu, visually position your load, and enter part counts, move distances and speeds.

The SiNet Hub Programmer™ software not only saves you time because it’s easy to learn and easy to use, it also eliminates most of the things that can go wrong during the set up and programming of a system.

We highly recommend that you try the SiNet Hub Programmer™ software before considering router mode.

✔ at least one Si™ indexer or indexer drive, firmware version 1.75 or later, connected to port 1.

✔ a step motor for your drive.

✔ a Pentium or better PC running Windows 95, 98 or NT with 10MB free disk space and an unused 9 pin serial port. The SiNet Hub Programmer™ software does not run with Windows 3.1.

✔ a PC serial interface cable (it comes with your Si™ indexer/drive)

✔ a modular telephone line cord for each indexer/drive (the hub comes with one 7 foot cable, and each drive includes a 7 foot cord. You can get longer cords anywhere telephone cords are sold, such as your local supermarket, discount store or Radio

Shack) multiple indexer-drives. The Hub 8 routes commands to individual drives based on address characters that your software sends along with the commands. It also routes messages from the drives back to the host PC or PLC. In Router Mode, the indexerdrives are commanded and queried using SiNet Command Language (SCL). Router

Mode is the most versatile way to use the hub, but also the most difficult because you’ll need a highly skilled programmer to write your host software.

✔ at least one Si™ indexer or indexer drive, connected to port 1.

✔ a step motor for your drive.

✔ a PC running Windows 3.1, 95, 98 or NT with an unused 9 pin serial port.

✔ a PC serial interface cable (it comes with your Si™ indexer/drive)

✔ a modular telephone line cord for each indexer/drive (the hub comes with one 7 foot cable, and each drive includes a 7 foot cord. You can get longer cords anywhere telephone cords are sold, such as your local supermarket, discount store or Radio

Shack)

✔ your own custom software to command and query the indexer/drives using SiNet

Command Language. This means you need a highly skilled computer programmer working with a language system like C, Visual Basic or Labview.

Connecting the Hub

All connections are made using four wire cables with RJ11 connectors, the same cords used to connect a telephone or modem to the wall jack. The connection to your

PC serial port also requires a small black adaptor to convert the RJ11 to the DB9 connector of your PC serial port.

Your hub comes with a 7 foot cable, and each Si drive includes a 7 foot cable and a black adaptor. You can use longer cables, up to 50 feet. Telephone line cords are easily available at your local supermarket, discount or electronics store.

Note: never connect the SiNet hub to a telephone outlet or to the modem port of your PC.

Note: if you decide to make your own cables, make sure that the ends are terminated just like a telephone cord, as shown below. If you mess this up, you could seriously damage the hub, your drives or your PC. If in doubt, don’t make your own cables.
