4.3.6. Read / write parameter motor speed switching points, command „h“ (68h)
This command is for read or write the motor speed switching points. Prior to reaching the target the motor
speed can be slowed down by two optional speeds (slow and precision) for absolutely precise positioning to the
target. The motor’s switchoff point might also be set to a certain value prior to reaching the target. The following
3 parameters are available:
Slow speed: At this point the SPA will go from high speed to slow speed.
Precision speed: At this point the SPA will go from slow speed to precision speed.
Switchoff point: SPA will stop motor at this position.
The individual switching points are indicated in relation to the target.
Example 1: Read parameter (slow speed = 2,00; precision speed = 0,70; switchoff point= 0,02)

4.3.7. Read / write parameter measuring unit, command „i“ (69h)
The command is for reading or writing the measuring unit in mm or inches.
Data = 0 (30h) = mm
Data = 1 (31h) = inch
Example 1: Read parameter (parameter = mm)
