User manual MOOG DS2000 BROCHURE

[. . . ] - Advanced, innovative product resulting from the use of `state of the art' hardware and software design tools and fully industrialised construction. - Standardised and totally interchangeable digital front card with integral fully functional keypad. - Universally understood parameter names in a user-friendly format. - Fully rationalised control circuitry design and layout yields greater functionality and flexibility. [. . . ] These filters permit the use of high gain values that result in minimised overshoot, improved stiffness, high dynamic responses and excellent servo-control performance. AUTOMATIC POWER OPTIMIZATION This algorithm automatically increases the torque of a motor up to its maximum speed rating, resulting in a true constant torque servomotor. Consequently motors wound with higher torque factors can be used. INDIRECT FIELD ORIENTED CONTROL (IFOC) With this vector control software algorithm the DS2000 will control induction motors fitted with a resolver feedback device (as defined at "Resolver interface"). Servomotor type performance is achieved while a much wider constant power range is available than with a synchronous servomotor. Motor selection (brushless or induction) is software programmable. All the normal parameters are retained, e. g. programmable filters, speed or torque control, etc. Moog · DS2000 · 04/05 3 GENERAL FEATURES The entire design of the DS2000 embodies the concept that failures are exponentially related to the number of components which have been, therefore, dramatically reduced. We have only selected leading edge technology components and have employed an extremely high percentage of SMD components, implementing a very highly automated assembly and test process. INTEGRAL POWER SUPPLY In order to make the DS2000 a self-contained stand-alone servodrive, we have integrated the following control and monitoring circuits into its on-board power supply: - Input power rectification and conditioning section. - Inrush current limiting `soft start' circuitry to reduce power supply current on power up. - High frequency Switch Mode Power Supply (SMPS) circuitry to feed all auxiliary control circuits. - IGBT motor regenerative power control circuit to ensure the excess motor energy is safely dissipated via a braking resistor. The braking resistors supplied with the DS2000 have been sized on medium-heavy duty cycles. Special ballast resistors can be required in case of particularly heavy duty cycles. - Auxiliary 24 Vdc control power input available for customer use. UNIVERSAL POWER CONNECTION The drive will accept any voltage between 65 and 506 Vac, three-phase, 50 or 60 Hz without any adjustment. This is achieved thanks to the continuous DC BUS detection circuit controlled from the Digital Signal Processor (DSP); all device protection thresholds are adjusted automatically. Obviously all circuit components are selected and rated for continuous use at the maximum ratings. INTEGRAL RESOLVER AND ENCODER INTERFACES Our standard digital control board provides both interface circuits and connectors to utilise either incremental encoder or resolver as a motor feedback device. - The resolver pole range covers from 2 to 24; the motor poles have to be an integer multiple of the resolver poles. - A simulated encoder signal is available that uses the resolver interface and provides user programmable encoder pulses (range: 64, 128, 256, 512 and 1024) and programmable marker pulse duration (range: 1, 1/2 and 1/4). [. . . ] - Saving of Digital Speed Reference: if the drive is reset, operations can be resumed with minimum set-up times. WINDRIVE USER INTERFACE Moog WinDrive is a graphical user interface application running on the Microsoft Windows family of operating systems. It allows the configuration of the Moog motor controller family. It provides the following main features: - configuration of various aspects of the drive via tabbed panels and dialogs - access to the Moog standard motor parameter database, and downloading of motor parameter sets - ability to create non standard motor parameter databases - ability to monitor faults and status - drive configuration upload and download - firmware upgrade - for some controller types, a graphical oscilloscope - access to the controller parameter database DRIVE CONFIGURATION The drive can be configured via the built-in keypad and display or via a PC.
