Ethernet Family of Products

by Jeff Kordik

If you’ve been visiting our website recently or receiving our latest newsletters, you probably know that we’ve been introducing stepper motor and servo motor drives with Ethernet communication. Below is a summary of the full offering to date.

Software applications can now communicate with our stepper and servo motor drives in real time, using the SCL and Q languages over standard 100 megabit Ethernet cabling, addressing and protocols. Ethernet can transmit data at 100 times the speed of CANopen and more than 1000 times faster than RS-232 and RS-485. The number and types of devices that can share a network are practically unlimited.

Even if you are just programming a Q drive for standalone operation, the Ethernet option can be more convenient than chasing down a USB-serial converter and trying to remember which COM port it uses. Just plug the drive into your office network, install our free, easy to use software, and you’re ready for programming and configuration.

On the stepper side, we currently offer four DC-powered step motor drives with Ethernet: the ST5-Q-EN, ST5-Q-EE with encoder feedback, ST10-Q-EN, and ST10-Q-EE with encoder feedback. Together, these models can control step motors ranging from NEMA sizes 11 to 34, producing up to 1200 oz-in of dynamic torque. If you prefer an AC-powered model, the STAC5 stepper drives are available in 120 and 220 VAC models and efficiently drive our specially designed, high torque NEMA 23 and 34 step motors. The ST5, ST10 and STAC5 stepper drives with encoder feedback can detect and prevent step motor stalls using Applied Motion’s proprietary stall prevention algorithm. Our auto-tuned digital current control provides smooth, quiet motion, while an advanced anti-resonance algorithm with electronic damping allows for maximum torque utilization, rapid acceleration, and fast settling times.

We also offer the Ethernet servo drive, SV7-Q-EE, with compatible servo motors in NEMA 17, 23, and 34 frame sizes, as well as 40, 60, and 80 mm metric frame sizes. With these servo motors, the continuous output power of the SV7 servo system ranges from 50 to 250 Watts.

All Ethernet stepper and servo motor drives are CE certified and ROHS compliant. AC-powered models are also UL recognized.
