February 8, 2011 - Servo2Go.com introduces the STAC5 step motor driver from Applied Motion Products. The STAC5 provides up to 5 amps per phase from a high bus voltage with sophisticated current control, delivering high torque over a board range of speeds. An advanced anti-resonance algorithm with electronic damping allows for maximum torque utilization and fast settling times. The STAC5 is available in 120VAC and 220VAC versions, both housed in a compact package.
All STAC5 models include 100Mbit Ethernet communication. The Ethernet interface is used to configure the STAC5 and motor, and also supports the SCL and Q languages over standard Ethernet cabling, addressing and protocols. The "S" models accept step and direction, analog input, joystick control, and streaming host commands using the SCL language. "S" models include four digital inputs, a 12-bit analog input, and two digital outputs. "Q" models add standalone programmable operation using the Q programming language.
This versatile language includes high-level features such as complex motion, multi-tasking, conditional programming, math functions, register access, and more. The "Q" models include 12 digital inputs, a 12 bit analog input, and six digital outputs. An encoder feedback option provides position verification, stall detection and/or stall prevention. Applied Motion's proprietary stall prevention algorithm monitors rotor lag and automatically reduces speed or acceleration to avoid motor stalls, allowing 100% torque utilization. The STAC5 can be purchased with a wide range of high torque step motors, optimized for use with the drive.
Three lengths of HT23 are available in single and double shaft configurations: HT23-552, HT23-553 and HT23-554, with holding torque ranging from 84 to 255 ounce-inches. Three lengths of HT34 are also available in single and double shaft configurations: HT34-495, HT34-496 and HT34-497, with holding torque ranging from 550 to 1700 ounce-inches. The STAC5 lists at $473 US/ea. Delivery is typically stock to 2 weeks.
