A35416 — TM: Temperature alarm threshold channel 10 exceeded

A35416 is issued by the temperature sensing of the Terminal Module 150 (TM150) when the temperature of channel 10, held in r4105[10], rises above the alarm threshold p4102[20]. As an alarm it triggers no protective response — the converter keeps running and the message only tells you that the channel-10 temperature has passed the set threshold. Depending on the drive's configuration, the same threshold condition can also be output as a fault (F) or as a message with no reaction (N).

• The channel-10 temperature r4105[10] measured via the TM150 temperature sensing has exceeded the threshold p4102[20] that initiates this alarm.
• For the sensor types "PTC thermistor" and "Bimetallic NC contact" (p4100[10] = 1, 4), the reported temperature is derived from the measured resistance r4101[10]: greater than 1650 ohms gives r4105[10] = 250 °C, 1650 ohms or less gives r4105[10] = -50 °C.

1. Read the current channel-10 temperature in r4105[10] and compare it with the alarm threshold p4102[20].
2. Let the sensor cool down — the manual's remedy is: Allow the temperature sensor to cool down to below p4102[20] - hysteresis (p4118[10]). Once this level is reached the alarm clears by itself, without acknowledgement.
3. If p4100[10] = 1 or 4 (PTC thermistor or bimetallic NC contact), check the resistance in r4101[10]: above 1650 ohms the channel reports 250 °C, at 1650 ohms or less it reports -50 °C, so the reported value follows the resistance.

• The alarm value in r2124 holds the temperature actual value at the time the alarm was initiated.
• Interpret r2124 as a decimal number; the value is given in steps of 0.1 °C.
• The message value appears as the placeholder %1 and carries this temperature.

• r4105[10] — the channel-10 temperature actual value measured via the TM150 temperature sensing; read it to follow the cool-down.
• p4102[20] — the alarm threshold of channel 10; the alarm initiates when r4105[10] rises above it and clears only once the temperature is below it again.
• p4118[10] — the TM150 threshold hysteresis; the alarm clears once the temperature is below p4102[20] minus this hysteresis.
• p4100[10] — the sensor type set for the channel; p4100[10] = 1, 4 covers "PTC thermistor" and "Bimetallic NC contact", the two types for which the resistance mapping applies.
• r4101[10] — the sensor resistance at the Terminal Module (titled TM120 sensor resistance in the parameter chapter); for a PTC thermistor or bimetallic NC contact it decides whether 250 °C or -50 °C is reported.
• r2124 — the alarm value; it stores the temperature at the time of initiation, interpreted as decimal in 0.1 °C.

The alarm needs no acknowledgement: once the sensor has cooled below p4102[20] minus the hysteresis p4118[10], A35416 clears by itself. If the drive's configuration outputs the same condition as a fault instead, it is only acknowledged by a POWER ON.
