ST5-IP-EN and ST10-IP-EN dc-powered EtherNet/IP drives control NEMA 11–34 step motors, producing up to 1,200 oz-in. of dynamic torque. ST5-IP-EE and ST10-IP-EE models include an encoder feedback option that can detect and prevent motor stalls using a proprietary stall prevention algorithm. The units support more than 100 commands and 130 registers over EtherNet/IP at 100 Mbps.
