Si Mm: Stop A Initiated - Siemens Sinamics S120 Diagnostic Manual

SINAMICS alarms
230502 <location>Power unit: DC link voltage, overvoltage
Message value: %1
Drive object: SERVO_COMBI, SERVO_SINUMERIK828
Reaction: NONE
Acknowledge: NONE
Cause: The power unit has detected overvoltage in the DC link on a pulse inhibit.
- device connection voltage too high.
- line reactor incorrectly dimensioned.
Fault value (r0949, interpret decimal):
DC link voltage [1 bit = 100 mV].
See also: r0070 (Actual DC link voltage)
Remedy: - check the device supply voltage (p0210).
- check the dimensioning of the line reactor.

230600 <location>SI MM: STOP A initiated
Message value: %1
Drive object: AFE_SINUMERIK_828, BIC_SINUMERIK_828, SERVO_COMBI, SERVO_SINUMERIK828, SIC_COMBI,
SIC_SINUMERIK_828
Reaction: OFF2
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The drive-based "Safety Integrated" function in the Motor Module (MM) has detected a fault and initiated STOP A
(pulse suppression via the safety shutdown path of the Motor Module).
- forced checking procedure of the safety shutdown path of the Motor Module unsuccessful.
- subsequent response to fault F30611 (defect in a monitoring channel).
Fault value (r0949, interpret decimal):
0: Stop request from the Control Unit.
1005: Pulses suppressed although STO not selected and there is no internal STOP A present.
1010: Pulses enabled although STO is selected or an internal STOP A is present.
1020: Internal software error in the "Internal voltage protection" function. The "internal voltage protection" function is
withdrawn. A STOP A that cannot be acknowledged is initiated.
9999: Subsequent response to fault F30611.
Remedy: - select Safe Torque Off and de-select again.
- replace the Motor Module involved.
Re fault value = 1020:
- carry out a POWER ON (power off/on) for all components.
- upgrade the Motor Module software.
- replace the Motor Module.
Re fault value = 9999:
- carry out diagnostics for fault F30611.
Note:
CU: Control Unit
MM: Motor Module
SI: Safety Integrated
STO: Safe Torque Off / SH: Safe standstill
