SINAMICS-Alarms
4: Encoder speed signal not plausible.
10: Stage 1: The ratio between the measured current and zero current is too low.
11: Stage 2: The ratio between the measured current and zero current is too low.
12: Stage 1: The maximum current was exceeded.
13: Stage 2: The maximum current was exceeded.
14: Current difference to determine the +d axis too low.
15: Second harmonic too low.
16: Drive converter too small for the measuring technique.
17: Abort due to pulse inhibit.
18: First harmonic too low.
20: Pole position identification requested with the motor shaft rotating and activated flying restart func-
tion.
Remedy: Re fault value = 1:
Check whether the motor is correctly connected.
Check whether motor data have been correctly entered.
Replace the Motor Module involved.
Re fault value = 2:
Open the motor holding brake (p1215) and bring the motor into a no-load condition.
Re fault value = 4:
Check whether the encoder pulse number (p0408) and gearbox factor (p0432, p0433) are correct.
Check whether the motor pole pair number is correct (p0314).
Re fault value = 10:
When selecting p1980 = 4: Increase the value for p0325.
When selecting p1980 = 1: Increase the value for p0329.
Check whether the motor is correctly connected.
Replace the Motor Module involved.
Re fault value = 11:
Increase the value for p0329.
Check whether the motor is correctly connected.
Replace the Motor Module involved.
Re fault value = 12:
When selecting p1980 = 4: Reduce the value for p0325.
When selecting p1980 = 1: Reduce the value for p0329.
Check whether motor data have been correctly entered.
Re fault value = 13:
Reduce the value for p0329.
Check whether motor data have been correctly entered.
Re fault value = 14:
Increase the value for p0329.
Re fault value = 15:
Increase the value for p0325.
Motor not sufficiently anisotropic, change the technique (p1980==1 or 10).
Re fault value = 16:
De-activate traversing/moving (p1982).
Re fault value = 17:
Repeat traversing.
Re fault value = 18:
Increase the value for p0329.
Saturation not sufficient, change the technique (p1980==10).
Re fault value = 20:
Before carrying out a pole position identification routine ensure that the motor shaft is absolutely sta-
tionary (zero speed).
