Nominal Current: 10A or 30A
For Brush-Commutated PMDC Motors. Up to 2100 W.
This PWM four-quadrant PMDC servo amplifier is fully enclosed in a rugged aluminum case which can be panel mounted for easy integration. The drive can be configured in a variety of torque and speed control modes with the mode of operation being set by simple DIP switches. The drive handles continuous currents up to 30 Amps and provides a peak current of 60 Amps. The drive is protected against over-current, over-temperature, motor short-circuit and incorporates state of the art MOSFET technology for maximum efficiency. Connectivity is achieved with simple screw-terminals for control/feedback inputs, supply power and motor connections.

| 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.
