The Altivar 32 drive is a frequency inverter for 200 to 500 V three-phase asynchronous and synchronous motors rated from 0.18 to 15 kW.  In combination with synchronous motors, Schneider Electric’s Altivar 32 variable speed drives offer optimized energy efficiency, and their high dynamic response optimizes application performance. The Altivar 32 variable speed drive is very compact to reduce the size of the equipment as well as its cost.

Altivar 32 drives provide safety functions and control system functions to meet the requirements of the most specialized applications. They offer various optional communication cards enabling seamless integration into the main control system architectures.

Modbus and CANopen

The Modbus and CANopen communication protocols are integrated as standard and can be accessed directly via the RJ45 communication port located on the front. ATV32 drives can also be connected to other industrial communication buses and networks by using one of the communication cards available as an option.

Modbus serial link

The Modbus serial link is used for connecting HMI and configuration tools, including: Magelis HMI terminals; remote graphic display terminal, and SoMove setup software.

CANopen machine bus

The CANopen machine bus is used for integration into control system architectures, especially when combined with Modicon M238 and M258 logic controllers or Lexium 32 motion controllers.

Optimized solutions for connection to the CANopen machine bus

To simplify setting up the Altivar 32 drive, three dedicated CANopen communication cards are available depending on the connection and connector types:

– CANopen daisy chain card with 2 x RJ45 connectors for daisy chain connection

– CANopen card for connection to the bus via 9-way SUB-D connector

– CANopen card for connection to the bus via terminals

Wider network integration

The drives have been designed to simplify connections to communication buses and networks, and add-on communication cards are supplied in “cassette” format for ease of mounting to the lower front of the drives as shown, viewed from the below

Accessing drive functions

All Altivar 32 drive functions can be accessed via the communication buses and networks for control; monitoring; adjustment, and configuration.  The speed reference and command may come from different sources.  For example, it may be a logic input or analogue I/O terminals, via the communication bus or network, or from remote display terminals.

The drive’s advanced functions can be used to manage switching of these drive control sources according to the application requirements. The communication periodic I/O data assignment can be selected using the network configuration software. Communication is monitored according to criteria specific to each protocol. Regardless of protocol type, the reaction of the drive to a detected communication fault can be configured as follows:

– Freewheel stop, stop on ramp, fast stop, or braked stop

– Maintain the last command received

– Fall-back position at a predefined speed

– Ignore the detected fault
