Description

The parameter PGEARI is used in conjunction with the PGEARO parameter to convert the control loop position and speed from SI units into increments.
The PGEARO parameter contains the number of increments that are moved if the path to be moved has a length of PGEARI.
The conversion is made according to the following formula:

Position[increments] = Position[SI] * PGEARO / PGEARI
Velocity[increments] = Velocity[SI] * PGEARO / PGEARI / 4000

If PGEARI = PGEARO, then there will be no conversion from SI units into increments. In this case, the position and velocity must be given in increments.

Position: 1046576 increments/turn for PRBASE = 20, or 65536 increments/turn for PRBASE = 16



Velocity: speed [UPM] * 2^PRBASE / (4000 *60)


For an example: see PGEARI

The user units that at are used for PGEARI and PGEARO are defined by PUNIT.
