7 Operating modes
Parameter Pr31 (default = 0) is used to select the operating mode. Every operating mode
controls speed using parameter Pr6 and can use parameter PR21 to limit the torque at the
motor (see the block diagram). Speed control will use as reference Pr7 or Pr6, depending on
the value of b40.2. Before changing Pr31, b40.2 must be set to 0 in order to avoid unwanted
movements of the motor. Therefore, it is possible to set Pr31 to the value that corresponds to
the selected operating mode. The parameter b99.11 is used to load the default parameters for
the selected operating mode. By setting b40.2 to 1, the operating mode will be turned on. All
operating modes need to control the motor in position (11, 13, 14, 15) by using the position
loop described in the diagram in the figure.
