Description: P2481 and P2482 define the gear box ratio for the positioning ramp down functionality. P2481 sets the motor shaft
side (gear box input).
Description: P2481 and P2482 define the gear box ratio for the positioning ramp down functionality. P2482 sets the load side
(gear box output).
Description: Sets the number of rotations of the motor shaft required to represent 1 unit of user selected units.
The following equation determines the number of motor shaft revolutions to stop:
