AC890

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.

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.

5-Mode Frequency Converter:

· V/F, Sensorless Vector, Flux Vector, Servo Drive, Line Regenerative (AFE)

· Built-in EMC Filters

· 2 Performance Levels (Advanced and High Performance)

· COMMS Options Available

 

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 (SSD Rail).

COMMON BUS Made Easy!
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.

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.

890 Series CS/CD

890 Series CS/CD units provide a common bus solution for multi-section drive applications. Multiple 890 Series CD Common Bus Drive inverter sections can be combined with a single 890 Series CS Common Bus supply unit, achieving substantial space savings and peripheral component savings within the enclosure. Additional 890 Series CS supply units may be paralleled to provide greater DC bus supply amperage.

How to Pick a CS

· Select the 890CD (common-bus drives), one for each section.

· Select the 890CS (common-bus supply) module by adding the HP (or currents) of all the CD drives.

· Select a reactor and braking resistor kit

· Order the common bus bar and exhaust duct kit from the options section
