Accessing Parameters
Section 4-5
Step 4 Storing changed parameter(s): To store changed parameter(s) in non-vola-
tile memory, write a 1 to Option Board parameter 971:
Step 5 Resetting the Option Board: To reset the Option Board, write a 2 followed
by a 1 to Option Board parameter 972:
Without changing AK or PNU, set PWE=1
The Option Board correctly executes the task and resets before responding.
After the PROFIBUS master has re-connected, the Option Board tries to exe-
cute the task a second time. The task fails because parameter 972 may only
be set to 1 if the current value is 2.
4-5-1-2 Accessing Inverter Parameters
When you address Inverter parameters, IND is used to select the parameter
group.
PNU represents the parameter number in that group. To address P160 for
example set IND=10h (P
@@@
) and PNU=0A0h (160).
Note It is important to use array tasks (6, 7 or 8) when accessing Inverter parame-
ters. IND is only interpreted if the Option Board executes an array task.
