コード 207902: <location>Drive: Motor stalled

Message value: %1 Drive object: SERVO Reaction: OFF2 (NONE, OFF1, OFF3, STOP1, STOP2) Acknowledge: IMMEDIATELY SINAMICS-Alarms Diagnostics Manual (DAsl), 03/2009 Cause: For a vector drive the system has identified that t he motor has stall for a time longer than is set in p2178. Fault value (r0949, interpret decimal): 1: Stall detection using r1408.11 (p1744 or p0492). 2: Stall detection using r1408.12 (p1745). 3: Stall detection using r0056.11 (only fo r separately excited synchronous motors). See also: p1744 (Motor model speed threshold sta ll detection), p2178 (Motor stalled delay time) Remedy: For closed-loop speed and torque control with speed encoder, the following applies: - check the speed signal (interrupted cable, polarity, pulse number, broken encoder shaft). - check the speed encoder, if another speed encoder was selected using the data set changeover. This must be connected to the same motor that is controlled for the data set changeover. If there is no fault, then the fault tolerance (p1744 and p0492) can be increased. For closed-loop speed and torque control without speed encoder, the following applies: - check whether the drive in the open-loop controlled mode (r1750.0) stalls under load. If yes, then increase the current setpoint using p1610. - check whether the drive stalls due to the load if t he speed setpoint is still zero. If yes, then increase the current setpoint using p1610. - if the motor excitation (magnetizing) time (r0346) was significantly reduced, then it should be increased again. - check the current limits (p0640, r0067). If the current limits are too low, then the drive cannot be magnetized. - check the current controller (p1715, p1717) and the speed adaptation controller (p1764, p1767). If the dynamic response was significantly r educed, then this should be increased again. - check the speed encoder, if another speed encoder was selected using the data set changeover. This must be connected to the motor that is controlled for the data set changeover. If there is no fault, then the fault tolerance ( p1745) or the delay time (p2178) can be increased. For separately-excited synchronous motors (clos ed-loop control with speed encoder), the following applies: - check the speed signal (interrupted cable, polarity, pulse number). - ensure the correct motor parameterization (ratin g plate and equivalent circuit diagram parameters). - check the excitation equipment and the interface to the closed-loop control. - encoder the highest possible dynamic response of the closed-loop excitation current control. - check the speed control for any tendency to oscill ate and if resonance effects occur, use a bandstop filter. - do not exceed the maximum speed (p2162). If there is no fault, then the delay time can be increased (p2178).
