Message value: %1 Drive object: All objects Reaction: A_INFEED: OFF2 (NONE, OFF1) SERVO: OFF2 (NONE, OFF1, OFF3) VECTOR: OFF2 (NONE, OFF1, OFF3) Acknowledge: IMMEDIATELY (POWER ON) Cause: The temperature measured using the temperature s ensing of the Terminal Module (TM) (r4105) has exceeded the threshold value to initiate this fault (p4102[1]) - or the temperature exceeded the alarm threshold (p4102[0]) for longer than the dead time in parameter p4103. Please note that this fault can only be initiated if the temperature evaluation was activated (p4100 = 2 for KTY sensor or p4100 = 1 for PTC sensor). Fault value (r0949, interpret decimal): The hundred thousands and ten thousands location specifies the component number of the TMxx where the fault occurred. Alarm: Please note that Fault F35207 only caus es the drive to be shut down if there is at least one BICO interconnection between the drive and TM31. Remedy: - allow the temperature sensor to cool down. - if required, set the fault response to NONE (p2100, p2101).
