官方故障排除步骤
Message value: %1 Drive object: VECTOR Reaction: OFF2 Acknowledge: IMMEDIATELY Cause: A fault has occurred during the pol e position identification routine. Fault value (r0949, interpret decimal): 1: Current controller limited 2: Motor shaft locked. SINAMICS-Alarms Diagnostics Manual (DAsl), 03/2009 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 smal l for the measuring technique. 17: Abort due to pulse inhibit. 18: First harmonic too low. 20: Pole position identification requested with the mo tor shaft rotating and activated flying restart function. 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 rout ine ensure that the motor shaft is absolutely stationary (zero speed).
