FM-3 Programming Module Reference Manual
If the user decides to put a 5:1 reducer on the system, the user simply needs to change the Characteristic Length.
Now the belt travels 4.71" in 5 motor revolutions.
Characteristic Distance = 4.712
Scaling =
Characteristic Length = 5
Keep in mind that the characteristic length is always a whole number and the valid range is from 1 to 2000.
Note
User Units may affect end motor speed and could cause trajectory faults.
Because of internal math in the
Velocity Group
Enable Separate Distance Units Check Box
If checked, separate distance and velocity units, name and scaling will be enabled. If not enabled, the velocity units, name and scaling will be defined by the Distance Group.
Scaled Distance Name
If the user wants the velocity units to have a different distance scaling than the distance units a name can be entered here up to 10 characters. For example, the user distance units could be inches while the velocity units are feet per minute.
Velocity Distance Units Scale Factor
This parameter scales the Velocity Distance Units back to actual distance units. To do this, enter the number of distance user units that are equal to one velocity scaled distance unit.
