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. Minimum actuator travel distance of 1[μm].
*4. When the motor mounting position is right side parallel (LEY*R) or left side parallel (LEY*L), the rotation
direction selection is 0(+: Counter motors side).
CAUTION
When the stopper type home position return is used and the actuator end is set to
the home position, please pay attention to the actuator movable range when
commanding the position to prevent collision with both ends of the actuator due to
overshoot.
When the origin (0 mm) is set at the actuator end, the movable range of this
actuator is from [+2mm] to [actuator stroke +2mm].
