ACS550-02/U2 User’s Manual 111
Application macros
User parameter sets
In addition to the standard application macros, it is possible to save two user
parameter sets into the permanent memory and load them at a later time. A user
parameter set consists of the user parameter settings, including Group 99: START-
UP DATA, and the results of the motor identification. The panel reference is also
saved if the user parameter set is saved and loaded in local control. The remote
control setting is saved into the user parameter set, but the local control setting is
not.
The steps below show how to save and load User Parameter Set 1. The procedure
for User Parameter Set 2 is identical, only the parameter 9902 values are different.
To save User Parameter Set 1:
• Adjust the parameters. Perform the motor identification if it is needed in the
application but it is not done yet.
• Save the parameter settings and the results of the motor identification to the
permanent memory by changing parameter 9902 to -1 (
USER S1 SAVE).
• Press (Assistant Control Panel) or (Basic Control Panel).
To load User Parameter Set 1:
• Change parameter 9902 to 0 (
USER S1 LOAD).
• Press (Assistant Control Panel) or (Basic Control Panel) to load.
The user parameter set can also be switched through digital inputs (see parameter
1605).
Note: Loading the user parameter set restores the parameter settings including
Group 99: START-UP DATA and the results of the motor identification. Check that
the settings correspond to the motor used.
Hint: The user can for example switch the drive between two motors without having
to adjust the motor parameters and to repeat the motor identification every time the
motor is changed. The user needs only to adjust the settings and perform the motor
identification once for each motor and then to save the data as two user parameter
sets. When the motor is changed, only the corresponding user parameter set needs
to be loaded, and the drive is ready to operate.
