F35407 — TM: Temperature fault/alarm threshold channel 11 exceeded

F35407 is raised by the temperature evaluation of the Terminal Module 150 (TM150), channel 11. The drive initiates it when at least one of two conditions is fulfilled: the alarm threshold has been exceeded for longer than the delay time set in the timer, or the fault threshold has been exceeded outright. The same condition can also be output as an alarm (A) or as a message without reaction (N), depending on the drive configuration. Note that this fault only causes the drive to shut down if there is at least one BICO interconnection between the drive and the Terminal Module.

• The alarm threshold of channel 11 (p4102[22]) has been exceeded longer than the time set in the timer (p4103[11]).
• The fault threshold of channel 11 (p4102[23]) has been exceeded.

1. Read the fault value in r0949 (interpret decimal): it contains the temperature actual value of channel 11 at the time the message was initiated, in 0.1 °C. Compare it with the current temperature at connector output r4105[11].
2. Check the sensor type set in p4100[11]. For sensor type "PTC thermistor" or "Bimetallic NC contact" (p4100[11] = 1, 4), read the sensor resistance r4101[11]: if it is greater than 1650 ohms, the drive sets the temperature r4105[11] = 250 °C; if it is 1650 ohms or less, it sets r4105[11] = -50 °C.
3. Determine from the settings which of the two trigger conditions applies: the alarm threshold p4102[22] together with the timer p4103[11], or the fault threshold p4102[23].
4. Allow the temperature sensor to cool down until it is below the fault threshold p4102[23] minus the hysteresis p4118[11].
5. If required, set the fault response to NONE for this fault via p2100 and p2101.

• r0949, interpret decimal: the temperature actual value at the time the fault was initiated, in 0.1 °C.
• The current temperature actual value of the channel is displayed via connector output r4105[11] and can be interconnected.

• p4102 — holds the channel 11 thresholds: alarm threshold at index [22], fault threshold at index [23]; the sensor must fall below the fault threshold before the fault clears.
• p4103 — delay time p4103[11]: how long the alarm threshold may be exceeded before the fault is initiated.
• p4100 — sensor type of channel 11; the value 1 or 4 selects evaluation of a PTC thermistor or a bimetallic NC contact.
• r4101 — sensor resistance of the channel; for a PTC thermistor or bimetallic NC contact, whether it is above or at most 1650 ohms decides whether 250 °C or -50 °C is reported.
• r4105 — connector output with the channel 11 temperature actual value; can be interconnected.
• p4118 — hysteresis p4118[11]; the cooling target is the fault threshold p4102[23] minus this hysteresis.
• r0949 — fault value; read it with decimal interpretation to see the temperature at initiation.
• p2100 / p2101 — if required, enter this fault there and change its response to NONE.

Remove the condition before acknowledging: let the temperature sensor cool down until it reads below the fault threshold p4102[23] minus the hysteresis p4118[11], then acknowledge the fault and restart the drive. When the condition is configured as an alarm (A) or as a message without reaction (N), the manual specifies reaction NONE and acknowledgement NONE, so no acknowledgement is needed in those variants.
