Question:
The function blocks contained in the library LenzeMotionControlV3.lib such as L_MCProfileGenerator do not support the reversal of the direction of rotation (e.g. left attachment of the motor). How can a simple reversal be achieved using this library?
Answer:
At the corresponding function block (e.g. function block L_MCProfileGenerator from the library LenzeMotionControlV3.lib) two input and two output signals must be negated each:
a) Input signals: L_MCProfileGenerator.nNAct_v, L_MCProfileGenerator.dnFollowingError_p
b) Output signals: L_MCProfileGenerator.nNSet_a, L_MCProfileGenerator.dnDeltaPos_p
When the function block L_MCProfileGenerator is used, it must be taken into consideration that this function block requires a longer computing time when the touch probe function and/or overriding into a subsequent profile is performed. If the solution shown below should not be possible (task overrun) using the SEL function blocks, jump instructions with an IF-THEN decision can be used (these do not take as much computing capacity).
In the following example the reversal is achieved via the digital input E3 (programmed in CFS here).
