4.2.2 0-1* Define and Set-up Operations
A complete set of all parameters controlling the drive is called a setup. A fixed set of factory settings can be copied into 1 or more
setups.
Some of the advantages of having more than 1 setup in the drive are:
•
Run the motor in 1 setup (active setup) while updating parameters in another setup (edit setup).
•
Connect the 2 motors (1 at a time) to the drive. Motor data for the 2 motors can be placed in the 2 setups.
•
Rapidly change settings of the drive and/or the motor while the motor is running. For example, ramp time or preset references
via bus or digital inputs.
The active setup can be set as multi setup, where the active setup is selected via input on a digital input terminal and/or via the bus
control word.
To copy a setup to other setup, use parameter 0-51 Set-up Copy. To avoid conflicting settings of the same parameter within different
setups, link the setups using parameter 0-12 Link Setups. Stop the drive before switching between setups where parameters marked
not changeable during operation have different values.
0-10 Active Set-up
Default value: [1] Set-up 1
Conversion index: -
Select the setup to control the drive functions. Use Multi setup for remote selection.
Table 18: Option:
[1]
Set-up 1
Setup 1 is active.
[2]
Set-up 2
Setup 2 is active.
[9]
Multi Setup
Used for remote setup selections via digital inputs and the serial communication port. This setup uses the
settings from parameter 0-12 Link Setups.
