JVL’s SMC66, a separate stepper motor controller, is now available with full application support from Mclennan in the UK. It is intended for applications with limited space, high ambient temperatures, harsh environmental conditions or vacuum operation.
The SMC66 delivers precision control for small motors from NEMA frame sizes 08 to 34, with current ratings up to 6 A, and includes all the features of JVL’s integrated ServoStep drive and motion control technology, albeit without the stepper motor. Standard features include closed-loop control from absolute multiturn and incremental encoders, as well as external SSI encoder support, RS485 and a built-in ePLC for eight configurable digital or analogue I/Os. A compelling range of options provides multi-axis support with multi-industrial Ethernet communications via a built-in Ethernet switch, CANopen and IO-Link, as well as wireless communications via Profinet, Ethernet/IP or Modbus TCP. The IP42-rated SMC66 measures just 104 x 45 x 54.5 mm (L x W x H) and features 4-hole plate mounting, making it easy to install or adapt for higher-level protection with added cover protection.
For motion tasks in vacuum and harsh environments, Mclennan can advise on installation design and, through its distribution partnership with Phytron, the German motor specialist, supply stepper motors for harsh industrial, vacuum and UHV, cryogenic and space applications. A DIN rail adapter is available as an optional extra for convenient installation. 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 high step resolution provides up to 409,600 steps/rev with a speed resolution down to ±0.01 RPM. 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 0-5 V (12bit) analogue inputs with advanced filtering.
