STP-AC5 Hardware Manual Getting Started This manual describes the use of four different drive models. What you need to know and what you must have depends on the drive model. For all models, you’ll need the following: • 120VAC or 220VAC power. • a compatible step motor (see page 25) • a small flat blade screwdriver for tightening the connectors (included). • a personal computer running Microsoft Windows 98, 2000, NT, Me, XP, Vista, 7, or 8 with an Ethernet port.
STP-AC5 Hardware Manual Connecting the Drive to Your PC using Ethernet This process 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.
STP-AC5 Hardware Manual 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.
STP-AC5 Hardware Manual 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).
STP-AC5 Hardware Manual 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 you 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.
STP-AC5 Hardware Manual 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.
STP-AC5 Hardware Manual Connecting to the PC Regardless of which STP-AC5 model you are using, you will need to connect to a Windows PC via Ethernet to configure your drive. If you want to create and test a IQ® Programmer program you will also need to use your PC for that. To prepare a drive for Ethernet communication with your PC you must physically connect it to the drive using a CAT5 Ethernet cable and select an appropriate IP address.
STP-AC5 Hardware Manual Connecting AC Power Using the connector supplied connect to the AC supply per the diagram below. Use 16 AWG wire for Line (L) and Neutral (N). Use 14 AWG for Earth Ground ( ). Care should always be taken when working with high voltages. In regions where the single-phase supply is higher, an auto transformer can be used to drop the voltage to the correct level. Fusing The STP-AC5-1 contains an internal 8A fast acting fuse. The STP-AC5-2 contains an internal 3.5A fast acting fuse.
STP-AC5 Hardware Manual Connecting the Motor Never connect or disconnect the motor while the power is on. Note: it is highly recommended that you use a motor with a shielded cable with the STP-AC5. Always connect the cable drain wire to the drive’s terminal (next to the A+ terminal) The recommended Bimba motors for the STP-AC5 include shielded cables. See the Recommended Motors section for a list of part numbers.
STP-AC5 Hardware Manual Six lead motors can be connected in series or center tap. In series mode, motors produce more torque at low speeds, but cannot run as fast as in the center tap configuration. In series operation, the motor should be operated at 30% less than the rated current to prevent overheating. Winding diagrams for both connection methods are shown below. NC means not connected.
STP-AC5 Hardware Manual Connecting an Encoder (Requires the Encoder Feedback Option) The motors recommended for use with STP-AC5 drives are available with rear-shaft mounted encoders. Note: remember to always order a double-shaft motor if you need an encoder option.

STP-AC5 Hardware Manual Single Ended Digital Inputs The -EIP drive includes four single ended, optically isolated input circuits that can be used with sourcing or sinking signals, 12 to 24 volts. This allows connection to PLCs, sensors, relays and mechanical switches. Because the input circuits are isolated, they require a source of power. If you are connecting to a PLC, you should be able to get power from the PLC power supply.

STP-AC5 Hardware Manual The STP-AC5-E drives feature two digital outputs. These outputs can be set to automatically control a motor brake, to signal a fault condition, to indicate when the motor is moving or to provide an output frequency proportional to motor speed (tach signal). Or the outputs can be turned on and off by program instructions like Set Output. -EIP drives include four additional programmable outputs.

STP-AC5 Hardware Manual Motor Heating Step motors convert electrical power from the drive into mechanical power to move a load. Because step motors are not perfectly efficient, some of the electrical power turns into heat on its way through the motor. This heating is not so much dependent on the load being driven but rather the motor speed and power supply voltage. There are certain combinations of speed and voltage at which a motor cannot be continuously operated without damage.

STP-AC5 Hardware Manual Drive Heating While STP-AC5 drivers efficiently transmit power between the AC power and motor, they do generate some heat in the process. This will cause the temperature of the drive to rise above the surrounding air temperature and may also require that the drive be mounted to a heat conducting metal surface. For those who wish to calculate the power dissipation and temperature rise, the following information is provided: 1.

STP-AC5 Hardware Manual Mounting the Drive Use #6 screws to mount your drive. If possible, the drive should be securely fastened to a smooth, flat metal surface that will help conduct heat away from the chassis. If this is not possible, then forced airflow from a fan may be required to prevent the drive from overheating. • • • Never use your drive in a space where there is no air flow or where other devices cause the surrounding air to be more than 40°C.
