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. - Fully rationalised control circuitry design and layout yields greater functionality and flexibility. - High reliability resulting from optimised use of circuit components. [. . . ] 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. 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. 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. 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). - The incremental encoder interface is able to manage 1024, 2048, 4096 and 8192 pulses per motor mechanical revolution. FEATURES DS flexible thanks to WinDrive, the graphic interface based on the Windows operating system (95-98-2000-NT) POSSIBILITY OF ADDING SPECIAL PROGRAMS VIA SERIAL LINE Special variants to the firmware can be loaded using the WinDrive graphic interface, without intervening on the hardware and without opening the drive. ANALOG CONFIGURABLE OUTPUT A proper control signal connector pin allows the monitoring of the main characteristics: - speed and reference errors - current reference - current limit - phases electric position - detected current - B. E. M. F. and phase voltage - DC BUS voltage and tacho output CAN OPEN INTERFACE (optional) This digital board mounted option is used where the requirement for the master generated drive speed reference signal is to be transferred via CANbus. [. . . ] - Motor Code: WinDrive can be used to store in the drive a code identifying the motor being used. - 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 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.
