EFB MCW bit 11 Control word bit 11 received through the embedded fieldbus
interface.
32
FBA A connection
loss
Detected communication loss of fieldbus interface A changes
control mode to EXT2.
33
EFB connection
loss
Detected communication loss of embedded fieldbus interface
changes control mode to EXT2.
35
Other [bit] Source selection (see Terms and abbreviations on page 162
). -
19.12 Ext1 control mode Selects the operating mode for external control location EXT1
in vector motor control mode.
Speed
Zero None. 1
Speed Speed control. The torque reference used is 25.01 To rqu e
reference speed control (output of the speed reference
chain).
2
Torque Torque control. The torque reference used is 26.74 Torque ref
ramp out (output of the torque reference chain).
3
Minimum Combination of selections Speed and Torque: the torque
selector compares the speed controller output (25.01 Torque
reference speed control) and the torque reference (26.74
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.
