Function extension:
Previously, at standstill in positions close to or on a software limit position there was a chance that the software limit position monitoring would respond due to the virtually constant light jittering of the actual position value (fault message P04/P05). Following a fault reset, the monitoring was immediately re-enabled and the drive could no longer be moved back toward the travel range. This problem occurred occasionally, particularly during manual jog, as the software limit positions here are used as a target position to be approached and following the manual jog, if necessary, the drive is located exactly on the software limit position.
From version V2.0 onwards, the monitoring of the software limit positions has been extended, meaning that this problem now no longer occurs.
The mode for monitoring the software limit positions can be set via the new code C3042:
C3042 = 0: (New mode from Posi&Shaft V2.0 onwards, default setting, recommended).
When specifying a movement towards the travel range by manual jog or via a positioning profile, no fault message is triggered by the jittering actual position. The direction of movement is determined based on the current set position.
Along with the 'Positioning' and 'ManualJog' statuses, the 'Standby' template status is also monitored with regard to the software limit positions.
C3042 = 1: (Compatibility mode, response as Posi&Shaft <=V1.3)
In the case of a detected movement toward the travel range, a fault message is not actually triggered. The direction of movement, however, is determined based on the current actual position, so that the detected direction of movement is also toggled with the jittering of the actual position.
The 'Standby' status is not monitored as in previous versions with regard to software limit positions.
Note:
During manual jog (ManualJog status), as in previous versions, after reaching a software limit position, the message 'Warning NegPositionLimit' or 'Warning PosPositionLimit' is displayed irrespective of the C3042 setting.
