官方故障排除步驟
Message value: Parameter: %1 Drive object: VECTOR Reaction: NONE Acknowledge: NONE Cause: Synchronization is not permitted. Alarm value (r2124, interpret decimal): 1300: The control mode (p1300) has not been set to encoderless closed-loop speed control or V/f characteristic. 1910: Motor data identification activated. 1960: Speed controller optimization activated. 1990: Encoder adjustment activated. 3801: Voltage Sensing Module (VSM) not found. 3845: Friction characteri stic record activated. Remedy: Fulfill the conditions for t he line-drive synchronization. Re alarm value = 1300: Set the control mode (p1300) to encoderless closed-l oop speed control (p1300 = 20) or V/f characteristic (p1300 = 0... 19). Re alarm value = 1910: Exit the motor data identification routine (p1910). Re alarm value = 1960: Exist the speed controller opt imization routine (p1960). SINAMICS-Alarms Diagnostics Manual (DAsl), 03/2009 Re alarm value = 1990: Exit the encoder adjustment (p1990). Re alarm value = 3801: Connect-up a Voltage Sensing Module (VSM) and when c onnecting to an adjacent drive object ensure that the drive objects have the same basis clock cycle. Re alarm value = 3845: Exit the friction characteristic record (p3845).
