The user can invoke or disable the feature by setting Amp and Phase values in SystemConfig
window. Amp and Phase values all zero is to disable the feature, otherwise is to invoke the
feature. It should be enabled unless the system configuration either does not need it or
cannot tolerate it. A system with loose couplings or viscous loading generally does not need
this feature. If a system has compliant (springy) coupling and is absent appreciably viscosity,
it may not respond well to the active, anti-resonant loop in the drive. The anti-resonant
feature is not designed to damp such a 4

Interner Pulser: There is an internal pulse generator designed for Drive self-testing and
anti-resonance tuning. You can issue a motion by this simple controller.
Cycle check box: The motion will repeat if this box is checked.
Reverse check box: The motor shaft will reverse direction if this box is checked. Interval
