At the SPS/IPC/Drives 2012, Control Techniques, an Emerson (USA) business, launched seven members (M100 to M800) of the Unidrive M AC and servo drives family for manufacturing automation.
THE M200 DRIVE OFFERS A CHOICE of communications options such as CANopen, DeviceNet, Ethercat and others. The device is able to control functionality for frequency, speed, and torque. Output power ranges from 0,25 kW to 22 kW. The drive may be applied in conveyors, pumps, mixers and fans, where control is via a field-bus or Ethernet is required. The drives are configured using Codesys programming environment with standard IEC 61131-3 languages and standard Ethernet for communication across drives, I/O, HMIs, PLCs and other industrial devices. The Ethernet (using IEEE 1588 v. 2) communication achieves synchronization rates across the network of below 1 µs and update rates as low as 250 µs. Each Ethernet-enabled drive incorporates a dual port Ethernet RJ45-switch. The Unidrive M800 (for up to 1,2 MW) integrates the recently introduced MCi machine controller. Certain applications, such as electronic line shafts, can be set up without having to write a programming code. In these instances, the drives will start communicating with one another automatically, synchronizing their control loops.
Along with the drives according PC tools were developed. Unidrive M Connect is a drive configuration and monitoring software. It allows users to optimize drive tuning, to back up the configuration set and to troubleshoot. Machine Control Studio supports company’s integrated MCi machine control functionality. The software provides an automation development environment using IEC 61131-3 programming languages with Codesys. Both tools use the same communications components and have an operational focus, so the user does not need to know about their specific drives or parameter menus for tasks such as drive and application set up, system and drive monitoring, optimization of motor performance or even for writing advanced system programs.
