Overview of Alarms
300719
Axis %1 drive %2 motor not parameterized for delta operation
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.
Reactions: - 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.
- NC Stop on alarm.
Remedy: Please inform the authorized personnel/service department. Check and enter the
machine data for motor delta (motor 2).
Program Con- Switch control OFF - ON.
tinuation:
300720
Axis %1 drive %2 maximum motor speed invalid
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: Because of the high maximum motor speed in the drive MD 1401:
$MD_MOTOR_MAX_SPEED and the speed controller cycle in MD 1001:
$MD_SPEEDCTRL_CYCLE_TIME sufficiently high speeds can occur to cause a format
overflow. Example: A motor speed of 480,000 rpm can still be processed without error at
a speed controller cycle time of 125 µs.
Reactions: - 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.
- NC Stop on alarm.
Remedy: Please inform the authorized personnel/service department. Reduce the maximum motor
speed MD 1401: $MD_MOTOR_MAX_SPEED (speed for the maximum useful motor
speed) or set a smaller speed controller cycle in MD 1001:
$MD_SPEEDCTRL_CYCLE_TIME (speed controller cycle).
Program Con- Switch control OFF - ON.
tinuation:
300721
Axis %1 drive %2 zero-load current greater than rated motor current
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: The no-load current of the motor (MD 1136: $MD_MOTOR_NOLOAD_CURRENT) has
been set at a greater value than the rated current of the motor (MD 1103:
$MD_MOTOR_NOMINAL_CURRENT).
Reactions: - 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.
