SINAMICS alarms
203590 <location>TM: Module not ready
Message value: %1
Drive object: All objects
Reaction: Servo: NONE (ENCODER, IASC/DCBRAKE, OFF1, OFF2, OFF3, STOP1, STOP2)
Infeed: OFF2 (NONE)
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The Terminal Module involved does not send a ready signal and no valid cyclic data.
Fault value (r0949, interpret decimal):
Drive object number of the Terminal Module involved.
Remedy: - check the 24 V power supply.
- check the DRIVE-CLiQ connection.
- check whether the sampling time of the drive object involved is not equal to zero (p4099[0]).
205000 <location>Power unit: Overtemperature heat sink AC inverter
Message value: -
Drive object: AFE_SINUMERIK_828, BIC_SINUMERIK_828, SERVO_COMBI, SERVO_SINUMERIK828, SIC_COMBI,
SIC_SINUMERIK_828
Reaction: NONE
Acknowledge: NONE
Cause: The alarm threshold for overtemperature at the inverter heat sink has been reached. The response is set using p0290.
If the temperature of the heat sink increases by an additional 5 K, then fault F30004 is initiated.
Remedy: Check the following:
- is the ambient temperature within the defined limit values?
- have the load conditions and the load duty cycle been appropriately dimensioned?
- has the cooling failed?
205001 <location>Power unit: Chip overtemperature
Message value: -
Drive object: AFE_SINUMERIK_828, BIC_SINUMERIK_828, SERVO_COMBI, SERVO_SINUMERIK828, SIC_COMBI,
SIC_SINUMERIK_828
Reaction: NONE
Acknowledge: NONE
Cause: Alarm threshold for overtemperature of the power semiconductor in the AC converter has been reached. The response
is set using p0290.
If the chip temperature increases by an additional 15 K, then fault F30025 is triggered.
Remedy: Check the following:
- is the ambient temperature within the defined limit values?
- have the load conditions and the load duty cycle been appropriately dimensioned?
- has the cooling failed?
- pulse frequency too high?
