key to move to the next parameter. The parameters you must fill out are as follows:
Units Name – Enter the character string you wish to use for your distance units.
Decimal Places – Enter the number of digits after the decimal place you wish to use in all
distance parameters throughout the software (i.e. index distances/positions, PLS On/Off
points). Use the spinner window Up/down buttons to increase or decrease the number of
digits.
Distance Units Scaling – Enter the number of User Units the motor/load travels for each
revolution of the motor. You must enter the numerator and the denominator for this scaling
factor.
Note
User Units may affect end motor speed and could cause trajectory faults.
