6.7 Commissioning: Basic procedure
● "Mechanics configuration"
In this section you can parameterize a gear ratio for the used encoder. The gear ratio is
the ratio of encoder revolutions to revolutions of the drive shaft (load revolutions).
– "Number of load revolutions" enables you to enter the number of load revolutions
– "Number of encoder revolutions" enables you to enter the number of encoder
● "Actual value synchronization"
– "Actual value synchronization" enables you to put the actual values of both encoders
– "Actual value tolerance" enables you to enter the tolerance for the cross-check of the
– "Speed tolerance" enables you to specify the maximum tolerance for the cross-check
– "Maximum actual-value difference" shows the maximum difference between the load-
– "Additional actual-value tolerance" shows the additional maximum difference between

the load-side actual position value on the Control Unit and the load-side actual
position value on the second channel, which can occur due to the delay of the actual
value acquisition in the EnDat 2.2 converter.
