7.3 Example of Setting Motion Parameters for the Machine
Set the following seven motion parameters to enable motion control that suits the machine’s specifications.
• Reference Unit
• Electronic Gear
• Axis Type
• Position Reference
• Speed Reference
• Acceleration/Deceleration Settings
• Acceleration/Deceleration Filter Settings
7.3.1 Reference Unit
Pulses, millimeters, degrees, or inches can be used as the reference unit for motion control. The reference unit is
specified in Command Unit (motion fixed parameter 4). The minimum reference unit that can be specified is
determined by the above unit selection and the setting of Number of Decimal Places (motion fixed parameter 5).
7.3.2 Electronic Gear
In contrast to the reference unit input to the MP2100/MP2100M, the moving unit in the mechanical system is called
the “output unit.” The electronic gear converts position or speed units from reference units to output units for the
mechanical system without going through an actual mechanism, such as a gear.
When the axis at the motor has rotated m times and the mechanical configuration allows the axis at the load to
rotate n times, this electronic gear function can be used to make the reference unit equal to the output unit.
The electronic gear function is set using the motion fixed parameters shown in the following table. The electronic
gear is disabled when pulse is specified as the reference unit.
