SA45 : ElectroCraft CompletePower™ Drives
Technology: Bipolar Stepper Drive
Nominal Current: 5A and 10A
Nominal Current: 5A and 10A
For Stepper Motors. Up to 500W.
This bipolar stepper drive provides microstepping to 1/16 resolution built into a fully enclosed rugged aluminum case. It can be DIN-rail mounted or panel mounted for fast integration. The mode of operation is set by simple DIP switches. Features include an internal oscillator that allows operation of the drive at an internal speed set-point or with an external analog speed reference that can scale this set-point. Both the 5A and the 10A versions of this drive can be powered by the same range of voltage supplies. This drive is protected against over-current, over-temperature and incorporates the state of the art dual full bridge MOSFET driver for maximum efficiency. Connectivity is tool-free with RJ45-CAT5 plugs for the control inputs and push-type terminals for power. The optically isolated control circuit can be powered with an internal 5V supply on the drive for TTL step and direction compatibility or supply an auxiliary voltage supply for up to 24V logic step and direction.

| CompletePower Plus™ Setup Utility Software | Description ElectroCraft CompletePower™ Plus Set-up Utility is a Windows-based program used for the setup, parameterization, system diagnostics and motion control management of the ElectroCraft CompletePower Plus line of digital servo drives. The ElectroCraft CompletePower™ Plus Set-Up Utility will lead the user through a Step-by-Step Wizard to create the correct configuration information required for the user to run a particular motor with a particular drive. The result will be an "Application" file containing all of the information required to run the motor with the drive. System Requirements Computer ElectroCraft CompletePower™ Plus can be installed on any IBM™ PC compatible computer running: • Windows 95/98 • Windows NT 4 • Windows 2000 • Windows XP Display A VGA display is required. A color monitor display makes it possible to take full advantage of ElectroCraft CompletePower™ Plus's graphic interface. The recommended screen resolution is 1024 x 728. A resolution of 800 x 600 will also function properly. Printer The ElectroCraft CompletePower™ Plus Set-up Utility uses the default printer installed on your computer. For optimal resolution, especially when printing graphs, use a high resolution (300-dpi) laser or ink jet printer. Mouse A mouse or other pointing device is required to use ElectroCraft CompletePower™ Plus Set-up Utility. Serial I/O The ElectroCraft CompletePower™ Plus Set-up Utility can be configured to use the PC's serial port for communication between the host PC and an ElectroCraft drive. A RS-232 serial cable is required between the host PC and the drive. Download Disclaimer Software download and registration require Internet Explorer 7 and above, Firefox 3, or Safari.
