SINAMICS G List Manual, Edition 12.2004
Remedy:
Check the connection to the signal source for interruptions.
Check the magnitude of the impressed current - it is possible that the impressed signal is too low.
Please note that the input has a load resistor of 250 Ohm.
The input current measured by the TM can be read-out of r4052[x].

A03550
TM: Speed setpoint filter natural frequency > Shannon frequency
Reaction:
NONE
Acknowledge:
NONE
Cause:
The natural filter frequency of the speed setpoint filter (p1417) is greater than the Shannon frequency.
The Shannon frequency is calculated according to the following formula: 0.5 / p0115[0]
See also: p1417
Remedy:
Reduce the natural frequency of the speed setpoint filter (PT2 low pass) (p1417).
F03590 (N, A)
TM: Module not ready
Reaction:
OFF2 (DCBRAKE, ENCODER, NONE, OFF1, OFF3, STOP1, STOP2)
Acknowledge:
IMMEDIATELY (power on)
Cause:
The terminal module involved does not send a ready signal and no valid cyclic data.
Fault value (r0949, decimal):
Drive object number.
Remedy:
- check the 24 V power supply.
- check the DRIVE-CLiQ connection.

A05000 (N)
Power module: Overtemperature heatsink
Reaction:
NONE
Acknowledge:
NONE
Cause:
The alarm threshold for overtemperature at the inverter heatsink has been reached. The response is set using
p0290.
If the temperature of the heatsink 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?
Reaction upon N:
NONE
Acknowledge
upon N:
NONE
A05001 (N)
Power module: Overtemperature chip
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 initiated.
