2.5.3 Electronic Gear Setting Examples
The following is setting examples for each kind of load mechanical configuration.
( 1 ) Example A: Ball Screw
In the above machine system, if the reference unit = 0.001 mm, the setting of each parameter will be as follows:
• Moving Amount Per Machine Rotation = 6 mm/0.001 mm = 6000
• Counter fixed parameter No. 11 (Encoder Gear Ratio) = 7 (rotations)
• Counter fixed parameter No. 12 (Machine Gear Ratio) = 5 (rotations)
( 2 ) Example B: Rotating Load
In the above machine system, if the reference unit = 0.1 °, the setting of each parameter will be as follows:
• Moving Amount Per Machine Rotation = 360 °/0.1° = 3600
• Counter fixed parameter No. 11 (Encoder Gear Ratio) = 3 (rotations)
• Counter fixed parameter No. 12 (Machine Gear Ratio) = 1 (rotation)
