  • Did You Know? - Jerk Filter for S-Curves

    Dec
    31

    For applications that require S-curve acceleration and deceleration ramps, Applied Motion servo drives offer an easy-to-use jerk filter. The jerk filter is set in Hertz within Quick Tuner™, Applied Motion’s servo configuration and tuning software. It can also be set with the SCL command KJ. The lower the Hertz value the more pronounced the S-curve profile will be.

    S-curve acceleration/deceleration ramps are beneficial in positioning systems where instantaneous changes in speed may cause the load to jerk excessively. One example is when the load is connected to the motion actuator via a long moment arm.

    Applied Motion Products is pleased to introduce the STAC5 step motor driver. 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.
