Message value: Parameter: %1 Drive object: SERVO, VECTOR Reaction: OFF1 Acknowledge: IMMEDIATELY Cause: The conditions to record the fricti on characteristic are not fulfilled. Fault value (r0949, interpret decimal): 0046: Missing enable signals (r0046). 1082: The highest speed value to be approached (p3829) is greater than the maximum speed (p1082). 1084: The highest speed value to be approached ( p3829) is greater than the maximum speed (r1084, p1083, p1085). 1087: The highest speed value to be approached ( p3829) is greater than the maximum speed (r1087, p1086, p1088). 1110: Friction characteristic record, negative di rection selected (p3845) and negative direction inhibited (p1110). SINAMICS-Alarms Diagnostics Manual (DAsl), 03/2009 1111: Friction characteristic reco rd, positive direction selected (p3845) and positive direction inhibited (p1111). 1198: Friction characteri stic record selected (p3845 > 0) and negat ive (p1110) and positive directions (p1111) inhibited (r1198). 1300: The control mode (p1300) has not been set to closed-loop speed control. 1755: For encoderless closed-loop control (p1300 = 20), the lowest speed value to be approached (p3820) is less than or equal to the changeover speed, open-loop controlled operation (p1755). 1910: Motor data identification activated. 1960: Speed controller optimization activated. 3820... 3829: Speed (p382x) cannot be approached. 3840: Friction characteristic incorrect. 3845: Friction characteri stic record de-selected. Remedy: Fulfill the conditions to record the friction characteristic. Re fault value = 0046: Establish miss ing enable signals. Re fault value = 0840: Select OFF1 (p0840) only after the friction characteristic record has been completed. Re fault value = 1082, 1084, 1087: Select the highest speed value to be approached (p3829) less than or equal to the maximum speed (p1082, r1084, r1087). Re-calculate the speed points along the friction characteristic (p0340 = 5). Re fault value = 1110: Select the friction characteristic record, positive direction (p3845). Re fault value = 1111: Select the friction characteristic record, negative direction (p3845). Re fault value = 1198: Enable the permitted direction (p1110, p1111, r1198). Re fault value = 1300: Set the control mode (p1300) on the closed-loop speed control (p1300 = 20, 21). Re fault value = 1755: For encoderless closed-loop speed c ontrol (p1300 = 20) select the lowest speed value to be approached (p3820) greater than the changeover spee d of open-loop controlled operation (p1755). Re-calculate the speed points along the friction characteristic (p0340 = 5). Re fault value = 1910: Exit the motor data identification routine (p1910). Re fault value = 1960: Exist the speed controller opt imization routine (p1960). Re fault value 3820... 3829: - check the load at speed p382x. - check the speed signal (r0063) for oscillation at speed p382x. If required, c heck the speed controller settings. Re fault value = 3840: Make the friction characteristic er ror-free (p3820 - p3829, p3830 - p3839, p3840). Re fault value = 3845: Activate the friction charac teristic record (p3845).
