Differs to initial value
*1. Parameter is set to the recommended value. Please set parameter according to customer application.
*2. Mechanical resonance may occur depending on the shape or mounting orientation of the work piece. Please change
this parameter during initial configuration.
(Parameter initial configuration ⇒ Set the recommended parameter value ⇒ Operation start)
*3. Other than positioning mode: Actuator travel distance at 10 [μm/pulse] per pulse.
Positioning Mode: Minimum actuator travel distance of 1[μm].
*4. When the motor mounting position is right side parallel (LEFS*R) or left side parallel (LEFS*L), the rotation
direction selection is 0(+: Counter motors side).
