公式トラブルシューティング手順

Message value: %1 Drive object: VECTOR Reaction: OFF1 (NONE, OFF2) Acknowledge: IMMEDIATELY Cause: A fault has occurred while ident ifying the moment of inertia. 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: It is not possible to increase the speed by 10% as the minimum limiting is active. 6: It is not possible to increase the speed by 10% as the suppression (skip) bandwidth is active. 7: It is not possible to increase the speed by 10% as the maximum limiting is active. 8: The torque difference after the speed setpoint step is too low in order to be able to still reliably identify the moment of inertia. 9: Too few data to be able to reliably identify the moment of inertia. 10: After the setpoint step, the speed either changed too little or in the incorrect direction. 11: The identified moment of inertia is not plausible. 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, 5: - adapt the speed setpoint (p1965) or adapt the minimum limit (p1080). Re fault value = 3, 6: - adapt the speed setpoint (p1965) or suppre ssion (skip) bandwidths (p1091... p1094, p1101). Re fault value = 4, 7: - adapt the speed setpoint (p1965) or maximum limit (p1082, p1083 and p1086). Re fault value = 8: - the total drive moment of inertia is far higher t han that of the motor (refer to p0341, p0342). De-select rotating measurement (p1960), enter the moment of inertia p342, re-calculate the speed controller p0340 = 4 and repeat the measurement. Re fault value = 9: - check the moment of inertia (p0341, p0342). After the change, re-calculate (p0340 = 3 or 4) Re fault value = 10: - check the moment of inertia (p0341, p0342). After the change: Calculate p0340 = 3. Note: The moment of inertia identificati on routine can be disabled using p1959.2. See also: p1959
