Enhancing the capability of the Altivar ATV61 and ATV71 inverter drives, the optional integrated IMC controller card removes the need for an additional PLC in smaller application functions. The Schneider Electric Altivar IMC integrated controller card has eight tasks to suit different machine requirements (cyclic, event-triggered, free).

A task can be synchronized with the task of the drive in which it is embedded. This task manages the speed reference, the torque reference, the speed feedback, the torque feedback, the number of encoder pulses feedback in order to increase machine performance.

Access to all the other devices in the system architecture via CANopen is totally transparent due to FDT/DTM technology. Combined with other compatible products, such as Altivar variable speed drives, Lexium servo drives, Magelis HMI terminals, TeSys motor starters and contactors,

Application Functions

For machines that require functions to process data issued by analogue sensors/ actuators (voltage or current), temperature sensors, pressure or PID control sensors, the Altivar IMC card has, as standard, 2 analogue inputs (voltage or current) with 10-bit resolution and 2 analogue outputs (current) with 10-bit resolution.

High-speed counter function

To meet machine productivity requirements, the Altivar IMC has two embedded 100 kHz high-speed counters for each channel as well as four outputs. In addition, these high-speed counting inputs can be used as an incremental encoder (A/B) with a frequency of 100 kHz in order to adapt to the machine’s specific requirements.

The counters, combined with the master CANopen link make it quick and easy to create low-cost, high-performance multi-axis functions that suit the machine’s operating constraints. The PLCopen function-blocks specific to the motion control functions in the SoMachine software, ensure application development is quick and reliable.

Position control function

For crane an ATV71 with integrated IMC controller can be used for lifting, whilst also controlling an ATV32 for carriage motion, and further ATV32 for traverse control. Other position control options include creating a sequence in Lexium 32 servo drives, with communication with the Altivar IMC integrated controller card achieved by the use of discrete I/O, or by creating an application in the Altivar IMC card and controlling the Lexium 32A/ Lexium 32M servo drives and/or SD stepper motor drives via the master CANopen integrated link.

Communication function

Ethernet

The Altivar IMC integrated controller card has a built-in RJ45 Ethernet port (10/100 Mbps, MDI/MDIX) with Ethernet TCP Modbus, SoMachine on Ethernet, UDP, TCP and SNMP protocols.  It also includes an embedded Web Server and FTP Server.  As well as the default address based on the MAC address, it is possible to assign a controller IP address via a DHCP server or via a BOOTP server.

CANopen

The Altivar IMC integrated controller card has an embedded CANopen master which can be used to control devices on a communication bus.  This enables architectures based on CANopen to distribute I/O modules as close to the sensors and actuators as possible, thus reducing installation costs and improving communication with devices such as variable speed drives, servo drives.
