300725 Axis %1 drive %2 number of encoder marks of measuring system invalid
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: The number of encoder marks of the motor measuring system in the drive MD 1005:
$MD_ENC_RESOL_MOTOR (number of encoder marks of the motor measuring system) is zero or
greater than the maximum input limit.
Reaction: NC not ready.
The NC switches to follow-up mode.
Channel not ready.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
