Siemens F07985

Qué Significa el Fallo

Fault: Drive: Speed controller optimization (oscillation test)

Causas probables

• A fault has occurred during the vibration test
• Fault value (r0949, interpret decimal): 1: The speed did not reach a steady-state condition
• 2: The speed setpoint was not able to be approached as the minimum limiting is active
• 3: The speed setpoint was not able to be approached as the suppression (skip) bandwidth is active

Solución y Primeras Comprobaciones Seguras

1. check the motor parameters (rating plate data). After the change: Calculate p0340 = 3.
2. check the moment of inertia (p0341, p0342). After the change: Calculate p0340 = 3.
3. carry out a motor data identification routine (p1910).
4. if required, reduce the dynamic factor (p1967 < 25 %).
5. adapt the speed setpoint (p1965) or adapt the minimum limit (p1080).
6. adapt the speed setpoint (p1965) or suppression (skip) bandwidths (p1091 ... p1094, p1101).
