Parameter management

The reset input is normally closed by default. If parameter 7-9 Reset/Enable Logic is set to Normally open, the reported state will be inverted (0 =
1
closed, 1 = open).
7.4 Parameter Management
The PROFINET Module can read parameter values from and write parameter values to the soft starter. The card handles 1 parameter
at a time.
The device references parameters according to their position in the soft starter parameter list. Parameter number 1 corresponds to
parameter 1-1 Command Source. Refer to the VLT® Soft Starter MCD 500 Operating Guide for details of the soft starter parameters.
UNPREDICTABLE BEHAVIOR
Changing the values of the parameters in parameter group 20 Advanced Parameters may cause unpredictable behavior in the soft
starter.
-
Consult the local supplier before adjusting the Advanced Parameters.
