ABB Inverter Drive ACS355 Series

ACS355 Machinery Drive – Single phase Input variable speed drive (VSD)

The dive is programmed with parameters, and like all ABB drives, the parameters are organized into logical groups. The software set inside the drive is packed with features that allow the drive to tackle machinery applications. It comes with an 8-step sequence program that allows machine automation to be incorporated inside the drive (16 steps available from ABB). Timer functions can operate at different times of the day and supervision parameters can make decisions based on machine variables.
To enhance the machinery application the drive can be fitted with an interface to all modern field buses, and the I/O can be used to synchronize motors with a pulse train. The drives also have pre-programmed protection functions for the motor and the driven load, and the drive is fitted with a brake chopper as standard to help stop dynamic loads (external resistor required).
The motor control is scalar or vector (open or closed loop) control, allowing the ACS355 to tackle more precise applications. The drive can operate induction and PM motors, allowing for more complex machinery applications to be undertaken, and the built-in braking chopper allows for higher dynamic operations to be performed. The drive comes with a 2-channel STO (Safe Torque Off) as standard to SIL 3, PLe. The ACS355 can also be fitted with a range of fieldbus, encoder, or extended I/O options.
Target applications for this machinery drive are therefore: Conveyors, Material handling machines, Gates, doors, barriers, Compressors, Packaging machines, Bottling lines, Winders, etc. An IP66 variant suitable for F&B is also available via ABB. The drive can be used for controlling fans and pumps, but the ACS310 is more suited to these applications.
