03/2009 Overview of Alarms SINAMICS-Alarms Remedy: - check the parameterization (p1640, p3201, p3202). - check the interfaces to the excitation equipment (r1626, p1640). - check the excitation equipment. 207914 <location>Flux out of tolerance Message value: - Drive object: SERVO, VECTOR Reaction: OFF2 Acknowledge: IMMEDIATELY Cause: The difference between the flux actual value and setpoint has exceeded the tolerance: abs(r0084 - r1598) > p3204 + p3205 The cause of this fault is again reset for abs(r0084 - r1598) < p3204. The fault is only issued after the delay time in p3206 has expired. Remedy: - check the parameterization (p3204, p3205). - check the interfaces to the excitation equipment (r1626, p1640). - check the excitation equipment. - check the flux control (p1592, p1592, p1597). - check the control for oscillation and take the appropriate counter measures (e.g. optimize the speed control loop, parameterize a bandstop filter). 207918 <location>Three-phase setpoint generator operation selected/active Message value: - Drive object: A_INF, B_INF, S_INF, SERVO, VECTOR Reaction: NONE Acknowledge: NONE Cause: Only for separately excited synchronous motors (p0300 = 5): The current open-loop/closed-loop control mode is I/f control (open-loop) with a fixed current (p1300 = 18). The speed is entered via the setpoint channel and the current setpoint is given by the minimum current (p1620). It must be ensured that in this mode, the control dynamic performance is very limited. This is the reason that longer ramp-up times should be set for the setpoint speed than for normal operation. See also: p1620 (Stator current, minimum) Remedy: Select another open-loop/closed-loop control mode See also: p1300 (Open-loop/closed-loop control operating mode) 207920 <location>Drive: Torque too low Message value: - Drive object: SERVO, VECTOR Reaction: NONE Acknowledge: NONE Cause: The torque deviates from the torque/speed envelope characteristic in the negative direction (too low). See also: p2181 (Load monitoring response) Remedy: Adapt the load. 207921 <location>Drive: Torque too high Message value: - Drive object: SERVO, VECTOR Reaction: NONE Acknowledge: NONE Cause: The torque deviates from the torque/speed envelope characteristic in the positive direction (too high). Remedy: Adapt the load. © Siemens AG 2009 All Rights Reserved SINUMERIK 840D sl, 840Di sl, SINAMICS, Diagnostics Manual (DAsl), 03/2009 2-797
