• Modify MD 1142: $MD_FIELD_WEAKENING_SPEED (threshold speed for field weak-
ening) should be checked and, if necessary corrected.
• Call the SIEMENS AG, SIMODRIVE Hotline.
Switch control OFF - ON.
Axis %1 drive %2 configuration of two EnDat encoders not possible
%1 = NC axis number
%2 = Drive number
The MCU hardware does not allow two absolute encoders to be connected on one axis
with the EnDat interface.
- NC not ready.
- Channel not ready.
- NC Stop on alarm.
- NC Start disable in this channel.
- The NC switches to follow-up mode.
- Alarm display.
- Interface signals are set.
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).
Switch control OFF - ON.
Axis %1 drive %2 module number for measuring system not possible
%1 = NC axis number
%2 = Drive number
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!
- NC not ready.
- Channel not ready.
- NC Stop on alarm.
- NC Start disable in this channel.
- The NC switches to follow-up mode.
- Alarm display.
- Interface signals are set.
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.
Switch control OFF - ON.
Axis %1 drive %2 measuring system already used as motor measuring system
%1 = NC axis number
%2 = Drive number
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!
