Compact drive module saves space on the
panel
Panel builders and systems integrators can now mount a compact, low-voltage AC drive directly into their panels, with the introduction of ABB's new drive module.
Panel builders and systems integrators can now mount a compact, low-voltage 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 400V) and from 110 to 500kW (at 500V)
It features ABB's direct torque control, for a smooth motor operation through rapid response to variations in motor load.
The drive includes space for internal built-in EMC filtering as standard both radiated and conducted level 2 emissions to EN 61800-3 limits.
Internally mounted EMC filtering 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.
Further savings are available through an innovative cabling principle: 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.
This means faster maintenance and reduced 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.
The use of a separate control unit renders I/O connections easily accessible without opening the drive cover and allows placing of the I/O terminals in the most convenient location.
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.
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 physically small enough to fit even the most compact of cabinets.
In narrow configuration, for example, up to 160kW at 400V, it measures just 1120 x 330 x 467mm.
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.
It also detects I/O extensions, fieldbus modules and other options and offers guided commissioning for them.
A high degree of versatility derives from "adaptive programming", which extends the freely programmable I/O and extensive parameter selections for simplified programming.
This set of blocks can be programmed to perform any from a predefined function set, including all common mathematical and logical functions as well as switches, comparators, filters and timers.
Users define block inputs and connections to the drive I/O or the drive control and can create new I/O signals to modify the drive's speed or torque control.
User-specified functions, traditionally handled by additional relays and timers, can also be integrated into the drive.
