Operating modes of the drive
The drive can operate in several operating modes with different types of reference.
The operating mode is selectable for each control location (
Local
,
EXT1
and
EXT2
)
when the motor control mode is
Vector
(
). If the motor control mode is
Scalar
,
the drive operation mode is fixed to frequency control mode.
An overview of the control hierarchy and different reference types and control chains
is shown below.
Speed control mode
In speed control mode, the motor follows a speed reference given to the drive.
Speed control mode is available in both local and external control locations. It is
supported in vector motor control only.
Speed control uses speed reference chain.
