Siemens F07087 fault code meaning

Siemens / F07087

Series: G120-CU250S-2

Drive: Encoderless run is not possible at the set pulse frequency

converter

Meaning: Encoderless operation is not possible at the set pulse frequency (p1800). Encoderless operation is activated under the following conditions: - The changeover speed for encoderless operation (p1404) is below the maximum speed (p0322). - A control mode for encoderless operation is set (p1300). - A motor encoder fault triggers a fault reaction that switches to encoderless operation (p0491). See: p0491 (Motor encoder fault reaction "Encoder"), p1300 (Open-loop/closed-loop operating mode), p1404 (Changeover speed for encoderless operation), p1800 (Pulse frequency setting).

Drive: Encoderless run is not possible at the set pulse frequency

servo drive

Meaning: Encoderless operation cannot be performed at the set pulse frequency (p1800). Encoderless operation is activated under the following conditions: - The changeover speed for encoderless operation (p1404) is lower than the maximum speed (p0322). - The control mode for encoderless operation (p1300) is set. - A motor encoder fault triggers the fault reaction for encoderless operation (p0491). See: p0491 (motor encoder fault reaction "Encoder"), p1300 (open-loop/closed-loop operating mode), p1404 (changeover speed for encoderless operation), p1800 (pulse frequency setting value).

Drive: Encoderless run is not possible at the set pulse frequency

converter

Meaning: Encoderless operation is not possible at the set pulse frequency (p1800). Encoderless operation is activated by the following conditions: - The transition speed for encoderless operation (p1404) is lower than the maximum speed (p0322). - The control mode for encoderless operation (p1300) is set. - A motor encoder fault triggers the fault reaction for encoderless operation (p0491).

converter

Meaning: Encoderless operation is not possible at the set pulse frequency (p1800). Encoderless operation is activated under the following conditions: - The switchover speed for encoderless operation (p1404) is less than the maximum speed (p0322). - A control mode for encoderless operation is set (p1300). - A motor encoder fault triggers a fault reaction that switches to encoderless operation (p0491).
