The Altivar 31C drive is a frequency inverter for three-phase 200Vac...500Vac asynchronous motors rated from 0.8kW to 15kW.
The enclosed Altivar 31C offer with its rugged design compact size and integrated functions is specifically adapted to respond to numerous applications requiring an IP55 degree of protection in a hostile environment.
These characteristics also offer the possibility of installing the Altivar 31C drive as close to the motor as possible.
IP55 drive offering a remote solution which can be customized depending on the model
Drive integrating the Modbus and CANopen communication protocols
Numerous options for loading printing and saving drive configurations using the remote display terminal / SoMove setup software and the Simple Loader configuration tool

The Altivar 31C drive incorporates functions that are suitable for numerous applications including
- Material handling (conveyors / hoists)
- Packing and packaging machines (labelling machines / sack filling machines)
- Pumping applications (suction pumps / centrifugal pumps / circulating pumps / mono-pump and multi-pump stations and etc.)
- Machines equipped with fans (air or smoke extraction / plastic film making machines / ovens / boilers / washing machines)
- Specialist machines (mixers / kneaders / textile machines)

The Altivar 31C drive has six logic inputs -- three analog inputs / one logic/analog output and two relay outputs
Main integrated functions
- Motor and drive protection
- Linear / S / U or customized acceleration and deceleration ramps
- +/-speed
- 6 preset speeds
- PI regulator and references
- 2-wire / 3-wire control
- Brake sequence
- Automatic catching a spinning load with speed detection and automatic restart
- Fault configuration and stop type configuration
- Saving the configuration in the drive

Several functions can be assigned to one logic input.
