16.2.5.3 Positioning from standstill
Procedure
A distinction is made between two cases with regard to positioning from standstill:
• Case 1: The spindle is not synchronized.
This is the case if the spindle is to be positioned after switching on the control and drive or after a gear step
change (e.g. for a tool change).
MD31040 $MA_ENC_IS_DIRECT = 0
• Case 2: The spindle is synchronized.
This is the case if, after switching on the control and drive, the spindle is to be rotated through a minimum of
one revolution with M3 or M4 and then stopped with M5 (synchronization with the zero mark) before the first
positioning action.
