公式トラブルシューティング手順

Message value: Parameter: %1 Drive object: SERVO, VECTOR Reaction: NONE Acknowledge: NONE SINAMICS-Alarms Cause: The friction characteristic is incorrect. Alarm value (r2124, interpret decimal): 1538: The friction torque is greater than the maximum from the upper effective torque limit (p1538) and zero. This is the reason that the output of the friction characteristic (r3841) is limited to this value. 1539: The friction torque is less than the minimum from th e lower effective torque limit (p1539) and zero. This is the reason that the output of the friction characteristic (r3841) is limited to this value. 3820... 3829: Incorrect parameter number. The speeds entered in t he parameters for the friction characteristic do not correspond to the following condition: 0.0 < p3820 < p3821 <... < p3829 <= p0322 or p1082, if p0322 = 0 Therefore the output of the friction ch aracteristic (r3841) is set to zero. 3830... 3839: Incorrect parameter number. The torques entered in t he parameters for the friction characteristic do not correspond to the following condition: 0 <= p3830, p3831... p3839 <= p0333 Therefore the output of the friction ch aracteristic (r3841) is set to zero. See also: r3840 (Friction c haracteristic, status word) Remedy: Fulfill the conditions for t he friction characteristic. Re alarm value = 1538: Check the upper effective torque limit (e.g. in the field weakening range). Re alarm value = 1539: Check the lower effective torque limit (e.g. in the field weakening range). Re alarm value = 3820... 3839: Fulfill the conditions to set the param eters of the friction characteristic. If the motor data (e.g. the maximum speed p0322) are changed during commissioning (p0010 = 1, 3), then the technological limits and threshold val ues, dependent on this, must be re-calculated by selecting p0340= 5).
