97.17 OffsetIDC (offset DC current measurement)
Offset value
- in percent of M1NomCur (99.03) - added to the armature current measurement. OffsetIDC
(97.17)
adjusts ConvCurAct (1.16) and the real armature current.
Setting
OffsetIDC (97.17) to 0 disables the manual offset.
Commissioning hint:
In case a 2
-Q converter module is used and the motor turns with speed reference equals zero increase
OffsetIDC (97.17)
until the motor is not turning anymore.

97.19 ZeroCurTimeOut (zero current timeout)
After a command to change current direction
- see CurRefUsed (3.12) - the opposite current has to be
reached before
ZeroCurTimeOut (97.19) has been elapsed otherwise the drive trips with F5
57 ReversalTime
[
FaultWord4 (9.04) bit 8].
The reversal delay time 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. The time needed to change
the current direction can be longer when changing from motoring mode to regenerative mode at high motor
voltages, because the motor voltage must be reduced before switching to regenerative mode
- see also

tMargin (44.21).
Note:
ZeroCurTimeOut (97.19)
must be longer than RevDly (43.14).
