70
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.
NOTE NOTE
Some parameters are only implemented if the drive is disabled, stopped or tripped and the

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.
