Code 207985: <location>Drive: Speed controller optimization (oscillation test)

Message value: %1 Drive object: VECTOR Reaction: OFF1 (NONE, OFF2) Acknowledge: IMMEDIATELY SINAMICS-Alarms Cause: 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. 4: The speed setpoint was not able to be appr oached as the maximum limiting is active. 5: Torque limits too low for a torque step. 6: No suitable speed controller setting was found. Remedy: Re fault value = 1: - check the motor parameters (rating plate data). After the change: Calculate p0340 = 3. - check the moment of inertia (p0341, p0342). After the change: Calculate p0340 = 3. - carry out a motor data identification routine (p1910). - if required, reduce the dynamic factor (p1967 < 25 %). Re fault value = 2: - adapt the speed setpoint (p1965) or adapt the minimum limit (p1080). Re fault value = 3: - adapt the speed setpoint (p1965) or suppre ssion (skip) bandwidths (p1091... p1094, p1101). Re fault value = 4: - adapt the speed setpoint (p1965) or maximum limit (p1082, p1083 and p1086). Re fault value = 5: - increase the torque limits (e.g. p1520, p1521). Re fault value = 6: - reduce the dynamic factor (p1967). - disable the vibration test (p1959.4 = 0) and repeat the rotating measurement. See also: p1959
