Contrary to the BOP, AOP operator panels or the commissioning program
DriveMonitor, the STARTER commissioning (start-up) program offers a mask-
orientated quick commissioning, which is especially advantageous for users who
are using MICROMASTER for the first time. On the other hand, BOP, AOP and
DriveMonitor offer, in conjunction with the drive inverter, parameter-orientated
quick commissioning where the user is navigated through the menu tree mentioned
above.
NOTE
The MICROMASTER series of drive units is not available for 3-ph. 690 V AC.
