Corrected from:
Library: L_MC1P_MotionControlBasic (FAST Motion) V03.18.00.252
(update via Package Manager)
Response of the new version:
The described inaccuracy of the determined TP position no longer occurs.
What happens?
Under certain conditions, the touch-probe position determined via MC_Touchprobe is inaccurate. The inaccuracy of the determined TP position corresponds to the distance covered in a PLC cycle. I.e. accuracy decreases with increasing speed.
When does this behaviour occur?
The behaviour only occurs in the following configuration:
- The actual position comes from a motion drive, e.g. i700 servo inverter and
- the touch probe is evaluated via an EPM-S207 I/O module, terminal on the backplane bus of the controller.
Note:
The described behaviour does not occur, when the actual position is evaluated by an external encoder read in via the backplane bus.
Which products are affected?
Library: L_MC1P_MotionControlBasic (FAST Motion)
Short-term measures:
The inaccuracy of the determined TP position corresponds to the distance covered in a PLC cycle.
The difference can be subtracted from the determined TP position.
