Overview of Alarms
SIMODRIVE alarms
300500 Axis %1 drive %2 system error, error codes %3, %4
Parameters: %1 = NC axis number
%2 = Drive number
%3 = Error code 1
%4 = Error code 2
Definitions: The drive has signaled a system error.
Safety Integrated:
Request: In the corresponding cycle.
On FDD: Generator stop (corresponds to STOP B)
On MSD: Pulse and servo disable (corresponds to STOP A)
The error occurs if the computation time of the drive processor is not sufficient for the cycle indicated
in the additional information.
Error no.: 03, additional information: 40, monitoring cycle too small for SINUMERIK Safety Integrated.
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.
NC Stop on alarm.
Channel not ready.
Remedy: Notes on the error codes can be found in the chapter "Error codes of alarm 300500".
NC reset (POWER ON)
Safety Integrated: Increase the corresponding cycle or the subordinate cycle (e.g. current, speed,
position-control cycle) or deselect the functions which are not required.
Any further search for the precise cause of error can only be performed by the development team. The
displayed error codes must always be stated. Reinitialization of the drive.
Please inform the authorized personnel/service department. System Support, SIEMENS A&D MC,
Hotline (tel.: see alarm 1000).
Program Switch control OFF - ON.
Continuation:
300501 Axis %1 drive %2 maximum current monitoring
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: 1. A serious fault occured during actual current measurement.
2. The maximum current threshold was exceeded while the rotor position identification was active
(FDD only).
Reaction: Mode group 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.
Channel not ready.
Remedy: Please inform the authorized personnel/service department.
- Modify MD 1107: $MD_INVERTER_MAX_CURRENT (transistor limit current)
- Check the motor data (motor code)
- Check the controller data, current/speed controller gain too high
- Reduce MD 1145: $MD_STALL_TORQUE_REDUCTION (stall torque reduction factor).
- Check the power section and motor terminals (including motor protection), possibly power section
too small
- Increase MD 1254: $MD_CURRENT_MONITOR_FILTER_TIME (time constant for current
monitoring)
- Error in actual current measurement (if necessary, replace 611D power section or controller module)
- If rotor position identification is active, check MD 1019 $MD_CURRENT_ROTORPOS_IDENT
(current for rotor position identification) and, if necessary, reduce the setting.
Program Switch control OFF - ON.
