Overview of Alarms
SIMODRIVE alarms
300737 Axis %1 drive %2 configuration of two EnDat encoders not possible
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: The MCU hardware does not allow two absolute encoders to be connected on one axis with the EnDat
interface.
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.
Remedy: Please inform the authorized personnel/service department.
Disconnect one of the two absolute encoders: Replace the motor measuring system by using another
motor or use another encoder for direct measuring system.
Correct the corresponding entries in MD 1011: $MD_ACTUAL_VALUE_CONFIG (actual value
sensing configuration IM) or MD 1030: $MD_ACTUAL_VALUE_CONFIG_DIRECT (actual value
sensing configuration DM).
Program Switch control OFF - ON.
Continuation:
300738 Axis %1 drive %2 module number for measuring system not possible
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: The NC has assigned the direct measuring system to an axis which doesn't have a motor measuring
system. This error can only occur with the 810D!
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.
Remedy: Please inform the authorized personnel/service department. Check the configuration of the direct
measuring system. See NC-MD 30220: $MA_ENC_MODULE_NR and NC-MD 30230:
$MA_ENC_INPUT_NR.
Program Switch control OFF - ON.
Continuation:
300739 Axis %1 drive %2 measuring system already used as motor measuring
system
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: The NC has assigned the direct measuring system to a measuring system output which is already
used by another motor measuring system. This error can only occur with the 810D!
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.
Remedy: Please inform the authorized personnel/service department. Check the configuration of the direct
measuring system. See NC-MD 30220: $MA_ENC_MODULE_NR and NC-MD 30230:
$MA_ENC_INPUT_NR.
Program Switch control OFF - ON.
