Mechanical configuration (settings - encoder parameterization)
When enabled, you can parameterize up to 8 ratios, and switchover the
active gearbox stage via PROFIsafe.
Sets the factor to increase the tolerance for the crosswise data comparison
of the actual position between the two monitoring channels while the gear‐
box stage is being switched over.
This factor is active when actual value synchronization is both activated as
well as also deactivated.
It is obtained, depending on the following tolerance:
● Actual value synchronization activated: p9549 * position tolerance
● Actual value synchronization deactivated: Actual value tolerance * po‐
sition tolerance
Displays the active position tolerance. (product from the position tolerance
and actual value tolerance or velocity tolerance)
Sets the numerator for the gearbox between the encoder and load.
Activates/deactivates the direction of reversal for the gearbox.
