Parameters:
%1 = NC axis number
%2 = Drive number

Definitions:
In mixed operation MSD/AM (MD 1465 > 0) only closed-loop controlled AM mode is allowed (MD1466 <= MD1465).• Modify MD 1465: $MD_SWITCH_SPEED_MSD_AM (switchover speed MSD/AM)• Modify MD 1466: $MD_SWITCH_SPD_OPEN_LOOP_AM (switchover speed closed- loop/open-loop control AM) The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY (channel not ready).Reactions:
