Parameters: %1 = NC axis number
%2 = Drive number
Definitions: On the basis of its no-load current (MD 1136: $MD_MOTOR_NOLOAD_CURRENT (motor no-load
current), the connected motor is too large for the power section in use (continuous thermal current MD
1108: $MD_INVERTER_MAX_THERMAL_CURR (current limit for power section).
Reaction: NC not ready.

300723 Axis %1 drive %2 STS configuration of axes differ
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: The configuration of the control block MD 1003: $MD_STS_CONFIG (STS configuration) must be
identical for both axes on 2-axis modules.
Reaction: NC not ready.
The NC switches to follow-up mode.

are the same. (Do not change the default setting - this corresponds to the optimum configuration).
Program
Continuation:
Switch control OFF - ON.
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.

For standard motors: Reset the drive (delete the bootfile) and repeat the startup.
For third-party motors: Check and, if necessary, refer to the motor data sheet to correct MD 1112:
$MD_NUM_POLE_PAIRS (number of motor pole pairs).
Program
Continuation:
Switch control OFF - ON.
