Siemens F07900 fault code meaning
Siemens / F07900
Series: G110M, G120-CU240B-E-2, G120-CU250S-2
Drive: Motor stalled
converter
Meaning: The motor has operated at the torque limit for longer than the time set in p2177, at a speed below the threshold set in p2175. This message is also triggered if the speed oscillates and the speed loop output repeatedly returns briefly to the limit. The power unit thermal monitoring function may also have reduced the current limit (see p0290), causing the motor to stop. See: p2175 (Motor locked rotor speed threshold), p2177 (Motor locked rotor delay).

Series: G115D, G120D
Drive: Motor stalled
converter
Meaning: The motor has operated at the torque limit for longer than the time set in p2177, with the speed below the threshold set in p2175. This message is also triggered if the speed oscillates and the speed loop output repeatedly returns briefly to its limit. The power unit thermal monitoring function may also have reduced the current limit (see p0290), causing the motor to stop.

Series: G120C
Drive: Motor stalled
converter
Meaning: The motor has been operating at the torque limit for an extended period while below the configured speed threshold. This message is also triggered if the speed oscillates and the speed controller output repeatedly returns briefly to its limit. The power unit thermal monitoring function may also have reduced the current limit (see p0290), causing the motor to stop.

Series: G120X, G120XA
Drive: Motor stalled
converter
Meaning: The motor has operated at the torque limit for longer than the time set in p2177, below the speed threshold set in p2175. This message is also triggered if the speed oscillates and the speed loop output repeatedly returns briefly to the limit. The power unit thermal monitoring function may also have reduced the current limit (see p0290), causing the motor to stop. See also: p2175, p2177
Possible causes

Series: G130-G150
Drive: Motor stalled
converter
Meaning: The motor has operated at the torque limit for longer than the time set in p2177, with its speed below the threshold set in p2175. This message is also triggered if the actual speed oscillates and the speed controller output repeatedly reaches its limit momentarily. If simulation mode is active (p1272 = 1) and closed-loop control with a speed encoder is enabled (p1300 = 21), this locked rotor message is issued when the encoder signal comes from another motor (a motor that does not run according to the torque setpoint of the closed-loop control). See also: p2175 (motor locked rotor speed threshold), p2177 (motor locked rotor delay).

Series: G210X
Drive: Motor stalled
converter
Meaning: The motor has operated at the torque limit for longer than the time set in p2177, at a speed below the threshold set in p2175. In encoderless vector control (including DDC), this message is also triggered if the load starting current p1610 is set too small, or if the speed fluctuates and the speed controller output frequently reaches the limit. Phase loss has occurred in the motor cable. The power unit thermal monitoring function may also have reduced the current limit (see p0290), causing the motor to stop. See also: p2175 (Locked rotor speed threshold), p2177 (Locked rotor delay time).

servo drive
Meaning: The motor has been operating at the torque limit for longer than the time set in p2177, at a speed below the threshold set in p2175. This message is also triggered if the actual speed oscillates and the speed controller output repeatedly reaches its limit momentarily. See: p2175 (Motor locked rotor speed threshold), p2177 (Motor locked rotor delay time).

Series: S200
Drive: Motor stalled/speed controller reached end stop
servo drive
Meaning: The motor has been running at the torque limit below the speed threshold set in p2175 for more than 0.2 seconds. This message is also triggered if the actual speed oscillates and the speed controller output repeatedly reaches its limit briefly. The message may also be triggered by phase loss in the motor cable. See also: p2175, p2177.
