MOVI-C®: Inverter technology

If you were to strip down your machinery and plant technology, you're certain to find inverter technology inside. Inverters have, for decades, been used to regulate and monitor drive technology in applications such as conveyor lines, corner transfer units, storage and retrieval systems, and many more plant machinery modules bedsides. But is all inverter technology equal? And how future-proof is the current state-of-the-art?

The NEW ARRIVALS: MOVIDRIVE® application inverters

MOVI-C®: Inverter technology

When developing our new MOVI-C® modular automation system, one of the key things we looked at was whether current inverter technology will cope with the automation tasks of the next few decades. One approach would have been to take pre-existing components that are technically sound, tried-and-tested and, most importantly, reliable – and make them even better.

Instead, we chose to completely re-engineer inverter technology and take automation technology based on MOVI-C® to a whole new level. After all, we believe the future of automation is mapped out in every component, including inverter technology. That is precisely why the MOVI-C® modular automation system includes new MOVIDRIVE® application inverters. Although the name hasn't changed, the inverters have been completely redeveloped and redesigned. The end result is a new inverter platform for all standard motors.

Compact or modular – MOVIDRIVE® controls and monitors all types of motor

The MOVIDRIVE® application inverters are available as single-axis application inverters with rated outputs up to 315 kW and as modular multi-axis systems incorporating single-axis and double-axis modules with rated currents up to 180 A. They exhibit an overload capacity of up to 250% for dynamic motions. Both as single-axis application inverters and in the modular design, "made by SEW-EURODRIVE" inverter technology controls and monitors all types of motors, from synchronous and asynchronous AC motors with/without an encoder to asynchronous motors with LSPM technology or synchronous and asynchronous linear motors. Functional safety is of course built in and even the basic unit incorporates the safety function STO in PL e. More than 15 additional safety functions can be incorporated using safety option cards.

In practical applications, MOVIDRIVE® supports impressively straightforward and fast commissioning

To get your motor up and running, you can read off and input the type designation on the motor's electronic rating plate. Alternatively, you can also use the electronic catalog in the MOVISUITE® engineering software.

If your motor is not recognized, that's no problem either, as it can be brought into operation simply by using a calibration function. What's more, energy-saving functions such as regenerative power supply units, energy storage units and a standby mode ensure optimum energy efficiency. During breaks in operation, standby mode reduces the power consumption of the application inverter by up to 85% – without losing communication with the overarching PLC.

Applications are put into operation using both graphical editors, which make it incredibly easy to create motion functions, and automatic IEC code generation, which is an entry-level sequence programming solution.

MOVI-C® ensures everything falls into place

Everything falls into place in our new MOVI-C® modular automation system – the engineering software matches the control and inverter technology and everything comes together seamlessly with the drive technology.

  • V/f: highly robust for asynchronous motors without encoders
  • VFCPLUS: highly diverse for asynchronous motors with and without encoders
  • CFC: highly dynamic for asynchronous and synchronous motors with encoders
  • ELSM®: highly efficient for synchronous motors without encoders

Digital interfaces to the motor

A digital data cable makes the motor an active part of your data network, providing all motor data – such as encoder data, temperature data, commissioning data, and data from other sensors – to the application inverter and the connected networks at any time. This information can be used to capture detailed operational data and compile maintenance forecasts. As the type designations, serial numbers and logistics data associated with motors are identified and supplied automatically, an inventory of all the drives in a plant can be compiled automatically at the touch of a button. Repairs, exchanges and enhancements can be tracked and traced at any time.

  • Intelligent, digital connection using just one standardized hybrid cable to connect data transmission and power supply lines between the motors (synchronous machine and asynchronous machine) and the application inverters:
    • The data line is linked to the application inverter using a series-standard coaxial connector
    • Plug connector on motor or, alternatively, terminal box connection for on-site assembly
  • Available for motors up to size 315
  • Extremely robust, high-performance design for data transmission with coaxial data cable, ideal for especially space-saving installations
  • Also suitable for very long cables measuring up to 200 m
  • Fully integrated digital motor encoder in various designs
  • Data memory in the motor for drive and application data, automatic start-up of the application inverter without engineering tool
  • MOVILINK® DDI digital data interface for transmitting:
    • Information from the electronic nameplate
    • Brake and diagnostic data (e.g. temperature sensor data)
    • Encoder data, safe and non-safe
  • Brake control integrated into the motor for synchronous and asynchronous drive technology:
    • For holding brakes and working brakes
    • No need for brake control device in the control cabinet
    • Continuous electronic detection of switching status and brake wear
    • Transmission of brake diagnostic data via data interface to application inverter
    • Condition-based maintenance intervals, forward planning of maintenance work, wear information, even for difficult-to-access drives

Integrated MOVISAFE® safety technology

Integrated into the inverter technology

Due to the requirements laid down in technical standards and the drive to have humans and machines working hand in hand, the number of plant areas equipped with functional safety technology is constantly growing. As a result, functional safety is an integral part of any application.

By introducing MOVISAFE® CS..A safety cards, SEW EURODRIVE has made functional safety an integral element of all MOVI C® application inverters. Even the basic unit in the MOVIDRIVE® series features STO in PL e. All higher-level safety functions are achieved by inserting an option card, including all the necessary connections to the inverter technology – encoder, communication and STO. This helps you reduce costs to only what is necessary to achieve the functions you actually need.

Functions in the basic unit

  • STO (safe torque off)
  • SIL 3 to EN 61800-5-2, EN 61508
  • PL e to EN ISO 13849-1
  • Can be activated via safe inputs
  • Can be activated via safe communication if a CS..A safety card is inserted
  • Extremely short response times of 2 ms enable small safety clearances

MOVISAFE® safety card functions

  • Five scalable safety cards as appropriate to application requirements
  • More than 15 higher-level safety functions can be incorporated by inserting option cards
  • Can be inserted retrospectively at any time, no additional external cables needed
  • Also with additional multi-encoder input
  • Safe communication via PROFIsafe/PROFINET and FSoE – Fail Safe over EtherCAT®
  • STO safety function with PLe integrated in basic unit
  • Secure communication via PROFINET / PROFIsafe and EtherCAT® / FSoE
  • High-quality safety functions in the MOVISAFE® safety card, type CS...A:
    • STO, SS1, SS2, SBC, SBT, SOS, SLS, SSR, SLA, SSM, SLI, SDI, SCA, SLP
    • Just plug in the option card; no external connection cables are required for the encoder, communication or STO connection
    • Easily replace cards and devices using the pluggable memory key in the safety option
  • Easily start up the unit by entering parameters
  • Diagnostics and scope functions are fully integrated in the engineering software
  • For simple control of the STO, the safe inputs feature P/P and P/M topology
  • All safety parameters are part of the inverter data set; in the case of a unit replacement, all that is needed is to import the inverter data set into the new device
  • Both process and safety values can be recorded in the Scope diagnostics tool – this facilitates troubleshooting and diagnostics
