The SieiDrive TPD32 range is available in 30 standard models in two and four quadrant versions with 3-phase line voltage ratings of 230V AC - 400V AC, - 500V AC and - 690V AC.
Self contained IP20 standard compact enclosures are available for current ratings from 20A to 1050A.
There are higher power IP00 versions with an external bridge provide ratings from 1200A to 3300A.
The integrated field regulator uses a single phase supply with current rating to suit the DC drive and motor type.
Optional filters are available for full compliance with CEE - EN61800 - 3:2004 EMC directive.
A wide complement of built-in analog and digital I/O is available for machine interfacing and protection includes a motor thermistor input and relay outputs.
Speed feedback options include tachogenerator and/or digital or sinusoidal encoders.
The range includes a long list of advanced features to aid straightforward integration into the customers' application.
These include the following.
* Autotuning speed and current loops.
* Independent programmable linear and S-curve ramping.
* Minimum and maximum speed regulation.
* Programmable multispeeds.
* Current limit linked to speed.
* Adaptive gains and many more.
Special functions available include: 'Speed draw', where a configurable speed ratio in a multiple drive system can be applied to a main speed reference; the 'Auto capture' function enables the drive to engage smoothly to a running motor for a flying restart and the 'Droop' function is used to precisely balance the current between two drives that are connected to two mechanically coupled motors.
Options available include a separate and detachable programming keypad, I/O expansion cards and a wide selection of fieldbus interfaces including Profibus, DeviceNet, CANopen, and InterBus S.
A range of programmable application cards with predefined library functions provides a choice of advanced application solutions including full electronic line shaft control, wind/unwind control with torque in open or closed loop for load cell input, and a single axis positioning module with up to 64 preset position registers with absolute encoder support via an optional interface.
Gefrans EasyDrive PC configuration software allows the user to set up, diagnose and program the SieiDrive TPD32 Digital DC Drive in a graphical environment with advanced time saving features that include parameter setting via tree structured menus, wizard guided programming, graphical variables display with trend recorder and oscilloscope function, and multi-drop network management for up to 32 drives.
