If the Motion Control Kernel is downstream from the MCKInterface in the circuit, the
L_MckCtrlInterface FB provides the following process input for stipulating an override of the
positioning mode:
9.8.4.4 Position teaching
The MCK control word can be used to initiate "teaching" or "latching" of the MCK setpoint position
or the current position into the currently selected profile.
If the Motion Control Kernel is downstream from the MCKInterface, the L_MckCtrlInterface FB
provides the following process inputs for teaching:
Identifier
Data type
Information/possible settings
wPosMode
WORD
Override of the positioning mode set in the profile data
• Only bit 0 ... bit 3 of wPosMode are evaluated.
0 Positioning mode = setting in C01300/1...15
1 Absolute (shortest path)
2 Continuous
3 Relative
4 absolute (Cw)
5 absolute (Ccw)
8 Absolute (shortest path) to TP
9 Continuous to TP
10 Relative to TP
11 Absolute (Cw) on TP
12 Absolute (Ccw) on TP
All other possible settings are reserved for future extensions!
Bit Designation Description
14 PosTeachSetPos "1" ≡ Teach MCK set position into the selected profile
15 PosTeachActPos "1" ≡ Teach current position into the selected profile
