Attention:
Do not change the default values of M1ArmL (43.09) and M1ArmR (43.10)! Changing them will falsify the
results of the autotuning.

43.14 RevDly (reversal delay)
RevDly (43.14) defines the delay time in ms for the bridge reversal after zero current has been detected - see
CurCtrlStat1 (6.03) bit 13.
The reversal delay starts when zero current has been detected - see CurCtrlStat1 (6.03) bit 13 - after a
command to change current direction - see CurRefUsed (3.12) - has been given. After a command to change
the current direction the opposite current has to be reached before ZeroCurTimeOut (97.19) has been elapsed
otherwise the drive trips with F557 ReversalTime [FaultWord4 (9.04) bit 8].
Note:
ZeroCurTimeOut (97.19) must be longer than RevDly (43.14).

Group 44: Field excitation
44.01 FldCtrlMode (field control mode)
Field control mode selection:
0 = Fix
constant field (no field weakening), EMF controller blocked, field reversal blocked, optitorque
blocked, default
1 = EMF field weakening active, EMF controller released, field reversal blocked, optitorque blocked
Note:
It is not possible to go into field weakening range when M1SpeeFbSel (50.03) = EMF.

44.02 M1KpFex (p-part field current controller)
Proportional gain of the field current controller.
Example:
The controller generates 15 % of motor nominal field current [M1NomFldCur (99.11)] with M1KpFex (44.02) =
3, if the field current error is 5 % of M1NomFldCur (99.11).
