There are three cases of application for the management and alteration of parameters:
A. Changing parameters of an Servo-Inverter i700 online:
If a parameter is changed online, »PLC Designer« writes the parameter directly into the
corresponding servo inverter and, at the same time, changes the parameter in the»PLC
Designer« project.
N.B.:
The parameter change is not recorded in the Lenze Controller. In the event of a "cold reset" of
the controller, the parameter change in the servo inverter is lost.
In order to avoid this, log out with the »PLC Designer« and then log in again. (Menu commands:
Online  Logout / Online  Login)
Like this, the complete parameter set is written to the controller and is transferred to the servo
inverter.
After the transfer by log-in, the parameter set is only available in the servo inverter and in the
controller until the next switch-off of the system (it is not saved with mains failure protection).
B. Changing parameters of a Servo-Inverter i700 offline:
If a parameter is changed offline, the »PLC Designer« changes the value directly in the »PLC
Designer« project. When logging in on the Lenze Controller, the complete parameter set is
written to the controller, which, in turn, then transfers the parameter set to the servo inverter.
After the transfer by log-in, the parameter set is only available in the servo inverter and in the
controller until the next switch-off of the system (it is not saved with mains failure protection).
