EXAMPLE
First, the desired unit (column 1) and the desired decimal positions (DP)
must be determined along with the gear factor and, if applicable, the -
feed constant of the application. This feed constant is then depicted in
the desired position units (column 2). Then the desired time unit
2
is
converted into the time unit
2
of the motor controller (column 3). Finally,
all values can be placed in the equation and the fraction calculated:
1.) Desired unit at the drive-out (acceleration_units)
2.) feed_constant: How many position_units are 1 revolution (R
OUT
)?
3.) time_factor_a: Desired time unit2 per internal time unit2
4.) Gear factor (gear_ratio) R
IN
per R
OUT
5.) Insert values into equation
1. 2. 3. 4. 5.
