Schneider Electric frequency inverters Altivar 31С general industry series presentation

The Altivar 31C drive is a frequency inverter for three-phase 200…500 V asynchronous motors rated from 0.18 kW to 15 kW. The enclosed Altivar 31C offer with its rugged design, compact size and integrated functions is specifically adapted to respond to numerous applications requiring an IP 55 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.
Examples of solutions provided:
- IP 55 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.

Applications

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

Schneider Electric drive Altivar 31C series functions

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
- 16 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.

Special uses of Schneider Electric vfd Altivar 31C series

Use with a motor with different power to the drive rating
The device can power any motor which has a lower rating than that for which the drive was designed. For motor ratings slightly higher than that of the drive, check that the current taken does not exceed the continuous output current of the drive.

Test on a low power motor or without a motor
In a testing or maintenance environment the drive can be checked without having to resort to using a motor with the same rating as the drive (particularly useful in the case of high power drives). This use requires deactivation of motor phase loss detection.

Connecting motors in parallel
The drive rating must be greater than or equal to the sum of the currents and powers of the motors to be controlled. In this case, it is necessary to provide external thermal protection for each motor using probes or thermal overload relays. If three or more motors are connected in parallel, it is advisable to install a motor choke between the drive and the motors.
Special uses of Schneider Electric vfd Altivar 31C series
Switching the motor at the drive output
Switching can be carried out with the drive locked or unlocked. If the drive is switched on-the-fly (drive unlocked), the motor is controlled and accelerates until it reaches the reference speed smoothly following the acceleration ramp. This use requires configuration of automatic catching a spinning load (“catch on the fly”) and activation of the function which manages the presence of an output contactor.
