Description
Control word bit 11 received through the embedded fieldbus
interface.
Detected communication loss of fieldbus interface A changes
control mode to EXT2.
Detected communication loss of embedded fieldbus interface
changes control mode to EXT2.
Source selection (see Terms and abbreviations
Selects the operating mode for external control location EXT1
in vector motor control mode.
None.
Speed control. The torque reference used is
reference speed control
chain).
Torque control. The torque reference used is
ramp out (output of the torque reference chain).
Combination of selections
selector compares the speed controller output
reference speed control) and the torque reference
Torque ref ramp out) and selects the smaller of the two.
If speed error becomes negative, the drive follows the speed
controller output until speed error becomes positive again.
This prevents the drive from accelerating uncontrollably if the
load is lost in torque control.
Combination of selections
selector compares the speed controller output
reference speed control) and the torque reference
Torque ref ramp out) and selects the greater of the two.
If speed error becomes positive, the drive follows the speed
controller output until speed error becomes negative again.
This prevents the drive from accelerating uncontrollably if the
load is lost in torque control.
Selects the operating mode for external control location EXT2

Enables/disables local control (start and stop buttons on the
control panel, and the local controls on the PC tool).
WARNING! Before disabling local control, ensure that
the control panel is not needed for stopping the drive.
