300723 Axis %1 drive %2 STS configuration of axes differ
Parameters: %1 = NC axis number
%2 = Drive number

are the same. (Do not change the default setting - this corresponds to the optimum configuration).
Program Switch control OFF - ON.
Continuation:
300724 Axis %1 drive %2 number of pole pairs invalid
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: FDD: The configured number of pole pairs in the drive MD 1112: $MD_NUM_POLE_PAIRS is outside
the permissible range limits.
MSD: Modify MD 1134: $MD_MOTOR_NOMINAL_FREQUENCY (rated motor frequency) or MD
1400: $MD_MOTOR_RATED_SPEED (rated motor speed) is not correct.
Reaction: NC not ready.
