„ Electronic Gear Setting Example
The following example shows settings for various load mechanisms.
Electronic Gear Parameter Settings Example (A): Ball Screw
In the above mechanical system, to set reference unit = output unit = 0.001 mm, the set val-
ues for each parameter are as follows:
• No. 10 = = 6000
• Gear ratio
• No.11 = 7
• No.12 = 5
Gear Parameter Settings Example (B): Rotational Load
In the above mechanical system, to set reference unit = output unit = 0.1°, the set values for
each parameter are as follows:
•
•
• No.11 = 3
• No.12 = 1
