Cause : No motor detected comes when the absolute current value is so small after enabling the inverter pulses that no motor is detected.

Note: In the case of vector control and an induction motor, this alarm is followed by the fault F07902. See also: p2179 (Output load identification current limit).

- check the motor feeder cables.
- reduce the threshold value (p2179), e.g. for synchronous motors.
- check the voltage boost of the U/f control (p1310).
- carry out a standstill measurement to set the stator resistance (p0350)
