repeat the startup. Check drive MD 1101: $MD_CTRLOUT_DELAY (dead time of current control
circuit).
Program Switch control OFF - ON.
Continuation:

Parameters: %1 = NC axis number
%2 = Drive number
Definitions: On activating the star/delta switchover by drive MD 1013: $MD_ENABLE_STAR_DELTA, the motor
delta (motor 2) is not parameterized.
Reaction: NC not ready.
The NC switches to follow-up mode.
Channel not ready.
