Figure 6-13 Brake sequence
Indicates the last 4 trips of the drive.
Pr 61 to Pr 70 and Pr 71 to Pr 80 can be used to access and adjust advanced
parameters.
Example: It is desired that Pr 1.29 ( Skip frequency 1 ) is to be adjusted. Set one of the
parameters Pr 71 to Pr 80 to 1.29, the value of Pr 1.29 will appear in the corresponding
parameter from Pr 61 to Pr 70 . I.e. if Pr 71 is set to 1.29, Pr 61 will contain the value of
Pr 1.29 where it can be adjusted.
6.3 Parameter descriptions - Level 3
Set Pr 71 to Pr 80 to the required advanced parameter number to be accessed.
The value within these parameters will be displayed in Pr 61 to Pr 70 . Pr 61 to Pr 70 can
then be adjusted to change the value within a parameter.
