Tm: Temperature Fault/Alarm Threshold Channel 2 Exceeded - Siemens Sinamics S120 Diagnostic Manual

SINAMICS alarms
Note:
For PTC, the following applies:
- if r4101[0] > 1650 ohms, the temperature r4105[0] = 250 °C
- if r4101[0] <= 1650 ohms, the temperature r4105[0] = -50°C
The measured temperature is displayed in r4105[0].
This fault can only be initiated if temperature evaluation was activated (p4100[0] = 2 for KTY84 sensor, p4100[0] = 1
for PTC thermistor or p4100[0] = 4 for bimetallic NC contact).
Notice:
This fault only causes the drive to shut down if there is at least one BICO interconnection between the drive and the
Terminal Module.
Fault value (r0949, interpret decimal):
Temperature value multiplied by 10 at the point of initiation.
Remedy: - reduce ambient temperature of temperature sensor to below p4102[1] hysteresis.
- if required, set the fault response to NONE (p2100, p2101).

235208 <location>TM: Temperature fault/alarm threshold channel 2 exceeded
Message value: %1
Drive object: AFE_SINUMERIK_828, BIC_SINUMERIK_828, SERVO_COMBI, SERVO_SINUMERIK828, SIC_COMBI,
SIC_SINUMERIK_828, TM120
Reaction: Servo: OFF2 (NONE, OFF1, OFF3)
Infeed: OFF2 (NONE, OFF1)
Acknowledge: IMMEDIATELY (POWER ON)
Cause: For the temperature evaluation via the Terminal Module 120 (TM120), at least one of the following conditions to initiate
this fault is fulfilled:
- alarm threshold has been exceeded longer than that set in the timer stage (p4102[2], p4103[1]).
or
- fault threshold exceeded (p4102[3]).
Note:
For PTC, the following applies:
- if r4101[1] > 1650 ohms, the temperature r4105[1] = 250 °C
- if r4101[1] <= 1650 ohms, the temperature r4105[1] = -50°C
The measured temperature is displayed in r4105[1].
