8.11 Mechanical Data
Mechanical Transmission Elements
Mechanical transmission elements are gearboxes and feed mechanisms
between the motor shaft and the load. These data must be entered in
order to perform the load-side conversion of the physical parameters for
position, velocity and acceleration. To see if these parameters have been
entered correctly, move the shaft and compare the path followed with the
position feedback value and the path actually taken.
Gear Ratio
The gear ratio can be set using the following parameters
• A102, Gear, input revolutions
• A102, Gear, output revolutions
The parameters for the ratio between gear input and output are set here.
Example:
Fs5003f1_AE.WMF
Fig. 8-28: Setting the Gear Ratio Parameters
In the illustration above, 5 gear input revolutions (= motor revolutions)
were equivalent to 2 gear output revolutions. The proper parameter
settings for this would be :
Input revolutions of load gear = 5
Output revolutions of load gear = 2
Feed Constant
The feed constant defines how far the load moves linearly per output
revolution of the gear. It is stipulated in Parameter
A101, Feed constant.
The value programmed here is used along with the gear ratio for
converting the position, velocity, and acceleration data from motor
reference to load reference.
