Specifications

Details

AC890 System Drives are modular AC drive units that can be combined to form a complete multi-section drive system, saving space, reducing wiring, and providing unmatched system performance. Safe Torque Off feature (SIL3 or PLe level as per EN ISO13849 and EN61800-5-2) is provided in frames B-F. Conformal coating option available for dusty, humid, or corrosive environments.

The AC890 can control everything from induction motors to servo motors. AC890 provides V/F, sensorless vector, closed-loop flux vector and servo position control; from simple AC motor control sections to more demanding sections. The AC890 comes in a wide variety of sizes and ratings and input and output types, making it the right solution for virtually any motion control project.

COMMON BUS Drives (CD) are individual motor output sections that easily connect to a COMMON BUS Supply (CS) with a unique, easy-to-install DC bus bar system.

DC bus terminals are located at top of each drive section. Easy to use screw clamps secure the high power bus bars. This low cost, compact design significantly reduces wiring in common bus systems, saving time and material cost.

COMMON BUS Drives (CD)

*Have internal DC fuses
*Need no reactors
*Provide access to all feedback and networking options

STANDALONE Drives (SD)
The AC890 Standalone Drives are complete AC-input-to-AC motor output controller with power input and output terminals, and access to all feedback and networking options.

Performance Levels
AC890 frequency converters offer the level of performance that best suits your application needs. With 2 different performance levels, AC890 system allows the maximum flexibility of use.

*Advanced Performance:
Basic LINK VM function blocks: math functions, Boolean logic, timers, counters, One shots, threshold comparators, latches, plus: motion control firmware with added position loop, motion control function blocks, move incremental, move absolute, move home, line drive master ramp and section control, winder blocks (SPW, CPW), full function PID, state machine, and others.

*High Performance:
All Advanced Performance features, plus: Library of pre-engineered application specific LINK VM function blocks such as: shaftless printing, cut-to-length, precision winding, traversing, and others.

Shaftless Registration Control Solutions for Printing
Mechanical line shafts for printing are easily replaced with individual AC890 drives, capable of precise synchronization and printing registration adjustment to each section, guaranteeing perfect alignment of each color. AC890 High Performance Level features a library of pre-engineered application specific LINK VM function blocks, including shaftless printing, cut-to-length, precision winding, traversing, and others. FireWire protocol (IEEE1394) ensures data synchronization for the printing register control.

*125µS Cycle time
*Time Synchronization
*Deterministic Network

Active Front End - Line Regenerative Systems
Common Bus Drive sections can also be configured as Active-Front-End Input Sections, providing true lineregenerative 4-quadrant control with no harmonics and 1.0 power factor. The AC890 with AFE can also be configured for grid-tie inverter applications.

Requirements:
*Pre-charging Circuit
*LCL Filter

Performance:

*Fully Bidirectional Power Flow
*Overload 150% for 60 secs
*Sinusoidal Input Current
*Complies with IEEE 519

Larger AC890 systems can be matched with separate higher power Active Front End units. Multiple rows of AC890 Common Bus Drives are bridged together using Common Bus Adapter modules.
