What it means
A35415 is issued when the temperature (r4105[9]) measured using the temperature sensing of the Terminal Module 150 (TM150) exceeds the threshold value p4102[18] that initiates this alarm; the monitored input is channel 9 of the Terminal Module. Depending on how the drive is configured, the same condition can also be issued as a fault (F) or as a message without any reaction (N).
Why it appears
- The temperature (r4105[9]) measured using the temperature sensing of the Terminal Module 150 (TM150) has exceeded the threshold value p4102[18] that initiates this alarm.
- With sensor type "PTC thermistor" or "Bimetallic NC contact" (p4100[9] = 1, 4), the drive derives the temperature from the sensor resistance r4101[9]: above 1650 ohms it reports 250 °C, at 1650 ohms or below it reports -50 °C.
What to check
- Read the alarm value r2124 (interpret decimal) — it holds the temperature actual value at the time the alarm was initiated, in 0.1 °C.
- Compare the current temperature r4105[9] with the set threshold p4102[18] and check the sensor type in p4100[9]. With "PTC thermistor" or "Bimetallic NC contact" (p4100[9] = 1, 4), read the sensor resistance r4101[9]: a value above 1650 ohms yields 250 °C, a value of 1650 ohms or below yields -50 °C.
- Allow the temperature sensor to cool down until the measured temperature is below p4102[18] minus the hysteresis p4118[9]; the alarm then goes away by itself.
Reading the message value
- Alarm value r2124, interpret decimal: temperature actual value at the time of initiation, in 0.1 °C.
Parameters the manual names
- r4105[9] — CO: Spindle supplementary temperature actual value; the channel 9 temperature of the TM150 temperature sensing that this alarm monitors.
- p4102[18] — Spindle supplementary temperature fault threshold/alarm threshold; A35415 is initiated when r4105[9] exceeds this value.
- p4100[9] — Spindle supplementary temperature sensor type; 1 means PTC thermistor, 4 means Bimetallic NC contact.
- r4101[9] — TM120 sensor resistance; with a PTC thermistor or Bimetallic NC contact it decides whether the drive reports 250 °C (above 1650 ohms) or -50 °C (1650 ohms or below).
- p4118[9] — TM150 fault threshold/alarm threshold hysteresis; together with p4102[18] it defines the level below which the alarm clears.
- r2124 — Alarm value; holds the temperature actual value at the time of initiation, interpret decimal in 0.1 °C.
Acknowledging and restarting
You do not need to acknowledge this alarm: it goes away once the temperature measured on channel 9 drops below p4102[18] - hysteresis (p4118[9]). Until then, allow the temperature sensor to cool down. If the drive is configured to issue this condition as a fault (F), the manual specifies acknowledgement "IMMEDIATELY (POWER ON)"; issued with no reaction (N), it requires no acknowledgement either.
The same on every family
Every manual that describes A35415 gives it the same reaction, acknowledgement and message class.

Questions technicians ask
What does alarm A35415 mean on a SINAMICS drive?
The temperature (r4105[9]) measured using the temperature sensing of the Terminal Module 150 (TM150) has exceeded the alarm threshold p4102[18]. The message concerns channel 9 of the Terminal Module.
How do I clear alarm A35415?
No acknowledgement is needed: the alarm clears itself once the temperature falls below p4102[18] minus the hysteresis p4118[9]. Allow the temperature sensor to cool down until then.
Why does A35415 show a temperature of 250 °C?
With sensor type PTC thermistor or Bimetallic NC contact (p4100[9] = 1, 4), the drive reports 250 °C whenever the resistance r4101[9] is above 1650 ohms, and -50 °C at 1650 ohms or below.
Where can I see the temperature that triggered A35415?
In the alarm value r2124. Interpret it as a decimal number in 0.1 °C — it holds the temperature actual value at the time the alarm was initiated.
