(2) Parameter Setting Example Using Rotating Table
• Machine specifications: Rotating table axis rotates 10 times for every 30 rotations of the motor axis (Refer
to the following figure.)
• Reference unit: 0.1 °
To rotate the table 0.1 ° for 1 reference unit input under the conditions outlined above, i.e., 1 reference unit = 1
output unit, set the fixed parameters 6, 8, and 9 as follows:
• Fixed Parameter 6: Travel Distance per Machine Rotation = 360×/0.1× = 3600 (reference units)
• Fixed Parameter 8: Servo Motor Gear Ratio = m = 30
• Fixed Parameter 9: Machine Gear Ratio = n = 10
Note: 1. The gear ratio for fixed parameters 8 and 9 (m/n) may be constant, e.g., m = 3 and n = 1.
2. Set the SERVOPACK gear ratio to 1:1.
