Control from overriding system
Two external control locations EXT1 and EXT2 are available.
The user can select the sources of the MCB open and MCB close commands separately
for each location by parameters 82.20 MCB Ext1 commands and 82.21 MCB Ext2
commands.
The user can select the sources of the start and stop commands separately for each
location by parameters 20.01…20.10.
The operating mode can be selected separately for each location, which enables quick
switching between different operating modes, for example speed and torque control.
Selection between EXT1 and EXT2 is done via any binary source such as a digital input or
fieldbus control word (see parameter 19.11 Ext1/Ext2 selection).
The source of reference is selectable for each operating mode separately. For speed
reference setting go to parameter group 23 if Rpm is used, or parameter group 28 if Hz is
used. For fieldbus setting, go to parameter group 50, 51, 52, 53.
