External control

When the drive is in external control, control commands are given through:
• the I/O terminals (digital and analog inputs)
• the fieldbus interface (via the embedded fieldbus interface or an optional fieldbus
adapter module)
• external panel (assistant panel).
Two external control locations, EXT1 and EXT2, are available. You can select the
sources of the start and stop commands separately for each location by setting
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 by parameter
Ext1/Ext2 selection. You can also select the source of reference for each operating
mode separately, and the operation mode.
