Purpose
The settings are specific to a certain drive. Switch to the corresponding drive
using the appropriate softkey before configuring.
Using softkey "Recommended values", you can automatically preassign the
values of the particular startup screen form. Check the individual suggested
values.
(Settings – mechanical configuration/actual value sensing)
Meaning
Sets the ratio between the encoder and load in mm/revolutions for a linear
axis with rotary encoder.
Sets the tolerance for the crosswise comparison of the actual position
between the two monitoring channels.
The tolerance must be set higher (e.g. 12 degrees rotary and 1 mm linear)
for encoderless motion monitoring functions.
