Description

AC890 Parker AC Variable Frequency Drives (VFD)

The AC890 is a compact, modular systems drive engineered to control speed and position of open-loop and closed-loop, single- or multi-motor AC induction or servo motor applications. Includes Safe Torque Off (STO) feature (Frames B-F) to SIL3 or PLe level as per EN ISO13849 and EN61800-5-2.

Compatible with a wide range of feedback options, the AC890 is designed to work with any AC motor and virtually any speed/position feedback options. Common bussing is supported, with a variety of common supply and common drive modules available, in addition to standalone models for simpler applications.

Available in 1 to 1200 HP at 380-500V 3-phase, and 1 to 10 HP at 220V-240V 3 phase.

AC890 can be user configured for 5 different operating modes:

Open-Loop (volts/frequency) Control:

This mode is ideal for basic motor speed control.

Sensorless Vector Control:

With its ultra high performance sensorless vector algorithm, it delivers a combination of both high torque and close speed regulation without the need for any speed measuring transducer.

Closed-Loop Vector Control:

Full closed-loop flux vector performance can be achieved with the AC890 by simply adding an encoder feedback ‘technology box’. This provides 100% continuous full load standstill torque, plus a highly dynamic speed loop more than sufficient for the most demanding applications.

Servo Control:

Designed for the most demanding servo systems. The ultra fast control loops and process bus make the AC890 ideal for single or multi axis applications.

4 Quadrant Active front-end power supply module:

With this configuration, the energy is fed back into the mains supply with sinusoïdal currents and unity power factor; a very low current harmonic content is achieved.
