Example 2: Dynamic coupling with 1x4 and 2x2 axes grouped in pairs
Assumption regarding machine axes:
• 1. up to the 4th machine axis: AX1, AX2, AX3, AX4
Dynamic coupling for all slave axes:
• MD37262 $MA_MS_COUPLING_ALWAYS_ACTIVE[AX2] = 0
• MD37262 $MA_MS_COUPLING_ALWAYS_ACTIVE[AX3] = 0
• MD37262 $MA_MS_COUPLING_ALWAYS_ACTIVE[AX4] = 0
For a dynamic coupling, the master axis specified when defining the coupling (MASLDEF) is,
as standard, the reference axis for speed setpoint coupling and torque equalization control.
The definition of reference axis AX3 for the torque equalization control of the 3rd slave axis
AX4 is required for the application "1x4 axes" where the following machine data is set:
MD37253 $MA_MS_FUNCTION_MASK[AX4], Bit 1 = 1 (see part program)
