Schneider Electric Inverter Drive, 2.2 kW, 3 Phase, 400 V, 5.5 A, ALTIVAR 31 Series

The Altivar 31 drive is a popular frequency inverter created and designed for a three phase squirrel cage asynchronous motors. This particular VFD (Variable Frequency Drive) is very robust, compact in size and is user friendly. The Altivar AT31 VFD series is suitable for use for motors that have a rating between 0.18 kW and 15 kW and can cater for four different types of power supply – please refer to the datasheet for further information.

The Altivar 31 variable frequency drive incorporates functions that are suitable for the most common applications.
• Material handling, such as small conveyors and hoists.
• Packing and packaging machines.
• Specialist machines such as mixers, kneaders and textile machines.
• Pumps, compressor machines and fans.

• This VFD drive communicates on Modbus and CANopen industrial buses. These two different protocols are integrated as a standard into the drive.
• The drive is also supplied with a heatsink for normal environments and ventilated enclosures.
• Multiple units can be installed side by side to save space and can also be easily customised.
• Features six logic inputs, three analogue inputs, one logic/analogue output and two relay outputs.
• There are a few options and accessories that can be used with the Altivar 31 drive, things such as braking resistors, line chokes, EMC radio interface input filters and output filters, plates for mounting, UL type 1 conformity kit and an adapter plate for replacing an Altivar 28 drive.
• High levels of torque at low speeds via sensorless Flux Vector control.
• A totally enclosed drive with an IP55 protection rating.
• Fully equipped with a Telemecanique Vario switch disconnector, speed reference potentiometer and Run/Stop switch.
• Operation up to 50°C without derating.

• Motor and drive protection
• Linear, S, U and customised acceleration and deceleration ramps
• + and – speed, as well as 16 pre-set speeds
• PI references and regulator
• Two and three wire control
• Brake sequence
• Automatic catching a spinning load with handy speed detection and an automatic restart
• Fault configuration and stop type configuration as well as saving the configuration in drive
• Several functions can be assigned to one logic input

The 10 VDC power supply and the analogue input of the Altivar 31 inverter drive can operate with any potentiometer ranging from 1k to 10k ohms.

Conforms to EN 50178, IEC/EN 61800-2, IEC/EN 61800-3 standards, UL/CSA certification and to CE marking.
