Message value: %1 Drive object: SERVO, VECTOR Reaction: OFF2 (NONE, OFF1) Acknowledge: IMMEDIATELY Cause: A fault has occurred during the identification routine.

SINAMICS-Alarms 10: Motor has been incorrectly connected. 11: Motor shaft rotates. 20: Identified threshold voltage of the semico nductor devices lies outside the expected range 0... 10 V. 30: Current controller in voltage limiting. 40: At least one identification contains errors. T he identified parameters are not saved to prevent inconsistencies. 50: With the selected current controller sampling rate, the pulse frequency cannot be implemented. Note: Percentage values are referred to the rated motor impedance: Zn = Vmot.nom / sqrt(3) / Imot,nom 101: Voltage amplitude even at 30% maximum current amplitude is too low to measure the inductance. 102, 104: Voltage limiting whil e measuring the inductance. 103: Maximum frequency exceeded during t he rotating inductance measurement. 110: Motor not finely synchronized before the rotating measurement. 111: The zero mark is not received within 2 revolutions. 112: Fine synchronization is not realized within 8 seconds after the zero mark has been passed. 113: The power, torque or current limit is zero. 120: Error when evaluating t he magnetizing inductance. 125: Cable resistance greater than the total resistance. 126: Series inductance greater than the total leakage inductance. 127: Identified leakage inductance negative. 128: Identified stator resistance negative. 129: Identified rotor resistance negative. 130: Drive data set changeover during the motor data identification routine. 140: The setpoint channel inhibits both directions. 160: Accelerating when determining kT, moment of inertia or reluctance torque too short or the accelerating time is too long. 173: Internal problem. 180: Identification speed (maximum speed, rated speed, 0.9 * p0348) less than p1755. 190: Speed setpoint not equal to zero. 191: An actual speed of zero is not reached. 192: Speed setpoint not reached. 193: Inadmissible motion of the motor when identifying the voltage emulation error. 194: Supplementary torque (r1515) not equal to zero. 195: Closed-loop torque control active. 200, 201: Not possible to identify the voltage emulat ion error characteristic of the drive converter (p1952, p1953). Remedy: Re fault value = 0: - check whether the motor is correctly connected. Observe configuration (star/delta). Re fault value = 1... 40: - check whether motor data have been correctly entered in p0300, p0304... p0311. - is there an appropriate relationship between the motor power rating and that of the Motor Module? The ratio of the Motor Module to the rated motor current should not be less than 0.5 and not be greater than 4. - check configuration (star/delta). Re fault value = 2: - for parallel circuits, check the motor winding syste m in p7003. If, for power units connected in parallel, a motor is specified with a single-winding system (p7003 = 0), although a mu lti-winding system is being used, then a large proportion of the stator resi stance is interpreted as feeder cable resistance and entered in p0352. Re fault value = 4, 7: - check whether inductances are correctly entered in p0233 and p0353. - check whether motor was correctly connected (star/delta). Re fault value = 50: - reduce the current controller sampling rate. SINAMICS-Alarms Diagnostics Manual (DAsl), 03/2009 Re fault value = 101: - increase current limit (p0640) or torque limit (p1520, p1521). - check current controller gain (p1715). - reduce current controller sampling time (p0115). - it may be impossible to completely identify the L characteristic, as required current amplitude is too high. - suppress meas. (p1909, p1959). Re fault value = 102, 104: - reduce current limit (p0640). - check current controller P gain. - suppress meas. (p1909, p1959). Re fault value = 103: - increase external moment of inertia (if possible). - reduce current controller sampling time (p0115). - suppress meas. (p1909, p1959). Re fault value = 110: - before rotating measurement, traverse motor over zero mark. Re fault value = 111: - it is possible that encoder does not hav e zero mark. Correct setting in p0404.15. - encoder pulse number was incorrectly entered. Correct setting in p0408. - if zero mark signal is defective, replace encoder. Re fault value = 112: - upgrade encoder software. Re fault value = 113: - check the limits (p0640, p1520, p1521, p1530, p1531), correct the zero values. Re fault value = 120: - check current controller P gain (p1715) and if required, reduce. - increase the pulse frequency (p1800). Re fault value = 125: - reduce cable resistance (p0352). Re fault value = 126: - reduce series inductance (p0353). Re fault value = 127, 128, 129: - it is possible that current controller is oscillating. Reduce p1715 before next measurement. Re fault value = 130: - do not initiate a drive data set changeover during motor ident. routine. Re fault value = 140: - before the measurement, enable at least one direction (p1110 = 0 or p1111 = 0 or p1959.14 = 1 or p1959.15 = 1). Re fault value = 160: - extend accelerating time when determining kT, mo ment of inertia and reluctance torque, e.g. by increasing max. speed (p1082), increasing moment of inertia or reducing max. current (p0640). - in encoderless operation with load moment of i nertia, parameterize the load moment of inertia (p1498). - reduce the ramp-up time (p1958). - increase speed controller P-gain (p1460). - suppress meas. (p1959). Re fault value = 173: Re fault value = 180: - increase max. speed (p1082). - reduce p1755. - suppress meas. (p1909, p1959). Re fault value = 190: - set speed setpoint to zero. Re fault value = 191: - do not start motor data ident. rout ine while motor is still rotating. Re fault value = 192: - check closed-loop speed control (motor rotor may be locked or closed-loop s peed control is not functioning). - for p1215 = 1, 3 (brake the same as the s equence control) check the control sense (p0410.0). - ensure that enable signals ar e present during measurement. - remove any pulling loads from motor. - increase max. current (p0640). SINAMICS-Alarms - reduce max. speed (p1082). - suppress meas. (p1959). Re fault value = 193: - the motor has moved through more than 5° electric al (r0093). Lock motor rotor at one of these pole position angles (r0093): 90 °, 210 ° or 330 ° (+/-5 °) and then start identification. Re fault value = 194: - switch out all supplementary torques (e.g. CI: p1511). - for hanging/suspended axes: Lock motor rotor at one of these pole position angles (r0093): 90 °, 210 ° or 330 ° (+/-1 °) and then start identification. Re fault value = 195: - de-select closed-loop torque control (p1300 = 21 or 20, or set the signal source in p1501 to a 0 signal). Re fault value = 200, 201: - set pulse frequency to 0.5 * current controller frequen cy (e.g. 4 kHz for a current controller clock cycle of 125 us). - reduce cable length between Motor Module and motor. - read-out measured values (r1950, r1951) and ther efore determine suitable values for p1952, p1953 according to your own estimation.
