A new and compact drive module from ABB is perfect for panel-building applications. The drive's in-built EMC compliance saves time and money:
Panel builders and systems integrators can now mount a compact, LV AC drive directly into their panels, with the introduction of ABB's new drive module. The IP00 open chassis module is available in R7 and R8 frame sizes, for applications from 90 to 400kW (at 400 V) and from 110 to 500kW (at 500V). This new module features ABB's Direct Torque Control, for a smooth motor operation through rapid response to variations in motor load.
Built-in EMC filtering:
The drive features built-in EMC filtering as standard - both radiated and conducted level 2 emissions to EN 61800-3 limits. This means that space needed for the drive is unaffected. Removing the need for separate EMC filtering, for a special EMC cabinet and for post-construction testing saves both installation time and hardware costs for panel builders.
Optimised cabling:
Further savings derive through innovative cabling: motor cables connect into a separate cabling pedestal, bolted into the panel. After cabling, the drive slides over the pedestal and is locked into position. After commissioning, the drive is removed easily for maintenance, without disconnecting output cables, so saving process downtime.
Cable connection to the module is easy, with power input through the top and motor cable output from the side with optional top or bottom exit. The output busbars can be mounted on either side. This gives space savings within the cabinet through the reduced need for cabling and/or busbars. A separate control unit renders I/O connections easily accessible without opening the drive cover and allows convenient placing of the I/O terminals.
Easy cabinet assembly:
In addition to easy cabling, innovative fixing mechanics simplify installation, minimising the number of bolts required for mounting the drive. The DIN rail mounting of the control unit and the new panel mounting platform further ease attachment.
The detailed cabinet assembly instructions supplied with each drive make life easier for the panel builder, by including cabinet layout examples, required air volumes and all other necessary information.
Compact with many options:
A wide range of standard and optional control features are offered, all within a module designed specifically for panel-mounting. Internally-mounted options include EMC filters, braking chopper, common mode filters and varnished control boards.
In addition, there are I/O extension modules including a pulse encoder interface, fibre-optic linking and a choice of fieldbus options that can be plugged directly into the control unit.
The drive is ideal for a wide range of panel-building applications, being small enough to fit the most compact of cabinets. In narrow configuration, for example, up to 160kW at 400 V, it measures just 1120mm (h) x 330mm (w) x 467mm (d).
Easy commissioning and programming:
The drive's internal "Start-up Assistant" detects when the drive is turned on for the first time. It then guides the user through the commissioning process with help in selecting appropriate settings for motor nominal values, I/O configuration and application-specific parameters.
