3.4.7.2 Position limit values (C1223, C1224)
l Position limit values (C1223, C1224) define the permissible traversing range of the drive.
l The reference point for the position limiting values always is the machine zero point. Shifting
the real zero point does not result in a shift of the position limiting value with the regard to the
mechanical travel range limits. ( 3−34).
l Exceeding the limit positions causes a fault (P04, P05).
l In the event of a failure the drive brakes to standstill using the function FAIL−QSP" (default
setting); the ramp time QSP−Tif" can be adjusted under C0105.
Code Name Limits Note
C1223 Pos.limit+ 0.0000 ... 214000.0000 [units] Positive position limiting value
C1224 Pos.limit− −214000.0000 ... 0.0000 [units] Negative positive limiting value
Tip!
l The settings should not allow that the end of travel limit switches are reached during
operation.
l The max. traversing range amounts to ±16000 revolutions of position encoder.
l If the position limiting values exceed the internal area, the warning P18 (internal limitation) is
triggered. The limiting values are internally automatically limited to the possible area.
Positioning can only take place within these limits.
l The input values under C1223 and C1224 remain the same and need to be modified by the
user (if necessary).
l Display of internally limited position limiting values under C1220/10 and C1220/11 [units] and
under C1221/10 and C1221/11 [incr.].
