Notes
Some of the parameters mentioned in the following applications can only be accessed via the Expert list.
Ensure you select this when you enter the Parameter menu.
The Technological Units (PID loop) is a new feature of the current Control unit – firmware version 4.4. At
date of compiling this guide, the BOP-2 does not show these units. This is also the case for the IOP,
however a firmware upgrade will be released soon that will enable this feature. So currently the only way to
see these Tech Units is via the fieldbus interface. For this reason it is not necessary to select the
corresponding parameters P595 and P596 if you are only communicating to the drive via the BOP-2.
If you decide to use the Technological Units, there is a sequence that should be followed to enable this
feature: -
1. Set P10 = 5
2. Set P596 = 100 (or the scaling factor recommended in the App sheet)
3. Set P595 = X (e.g. 1 = %, 4 = C, 5 = Pa, etc. - determined by your application)
4. Set P10 = 0
5. Continue with the parameters listed in the chosen application.
