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.

Our less expensive “S” models can be controlled in real time by a host!

Most of Applied Motion’s newer drives feature “S”, “Q”, and “Si” models. Each of these model types offer different ways for fitting into the overall control architecture of the device being designed.

  • “S” models are typically controlled by an external pulse source – step & direction.
  • “Q” models are programmable via an ASCII based programming language and can act as stand alone or host controlled motion controllers.

Applied Motion Products’ DSP-based stepper drives with encoder options offer a unique feature. The stall prevention feature of the STAC6, ST5, ST10 stepper drives and STM integrated steppers not only prevents stalling, but maintains the position of the motor at rest as well. This feature is called position maintenance.
