Separate stepper motor controller

With all the features of JVL’s integrated ServoStep drive and motion control technology, albeit without the stepper motor, the SMC66 delivers precision control for small motors from NEMA frame sizes 08 to 34 - with current ratings up to 6 Amps. Closed-loop control from absolute multiturn and incremental encoders as well as external SSI encoder support is included as standard along with RS485 and a built-in ePLC for eight configurable digital or analogue I/Os. Through a compelling choice of options, multi-axis support is covered with multi–Industrial Ethernet comms’ via a built-in Ethernet switch, CANopen, IO-Link and wireless comms’ via Profinet, Ethernet/IP, or Modbus TCP.

The IP42 rated SMC66 measures just 104 x 45 x 54.5mm (l x w x h) with 4-hole plate mounting so is easily installed or adapted for higher level environmental protection with added cover protection. For vacuum and harsh environment motion tasks, Mclennan can advise on installation design, and from its distribution partnership with Phytron the German motor specialist, supply harsh industrial, vacuum and UHV, cryogenic and space rated stepper motors. A DIN rail adapter is optionally available for installation convenience. An open PCB version of the SMC66 is also available for OEM integration.

Depending on the version, up to six M12 connectors cover motor, encoder, and I/O including dual M12’s for daisy chaining drive-to-drive. The SMC66 can be optionally supplied with a separate STO connector and equipped for SoE Safety over Ethernet. The drive is powered from a separate 12-80 VDC supply, and its ultra-high step resolution provides up to 409,600 steps/rev with a speed resolution down to ±0.01rpm. Real-time adjustment allows speed, torque, acceleration, target position and many other parameters may be changed "on-the-fly” in synchronisation with the compliment of eight freely configured 24V DC digital I/O or 0-5V (12bit) analogue inputs with advanced filtering.

The optional Ethernet support covers all main protocols including Profinet, EtherNet/IP, SERCOS, EtherCAT, Powerlink and ModbusTCP/UDP with JVL’s MacTalk® software enabling the user to seamlessly swap protocols via an integrated Ethernet switch. Other options for multi-axis motion tasks include DMX512 digital comms’ for the entertainment/lighting industries as well as Bluetooth and the Zigbee low power network. All of the numerous bus and comms’ options available are supported with cables and connectors in various lengths for seamless multi-axis integration.

Whilst the SMC66 can operate without encoders, the drive supports a wide range of absolute multiturn and incremental encoder types, allowing position verification for precision positioning tasks through semi-closed- loop or full closed-loop control with JVL’s PA0260 encoder PCB. For PC or IPC based applications, an ActiveX/OCX driver is available allowing interfacing to LABview, Excel, VB or other Windows-programs.

As a long-time distribution partner, Mclennan provides a complete application service for JVL, covering individual product selection, motor sizing and application advice through to complete motion system integration across JVL’s complete product range. Mclennan also has distribution partnerships with other selected motion control component and systems manufacturers. And, with its own comprehensive design and build service provides stepper and servo motor-based automation solutions from single components to complete motion-based sub-systems.
