10: Motor has been incorrectly connected.
11: Motor shaft rotates.
20: Identified threshold voltage of the semiconductor devices lies outside the expected range 0 ... 10
V.
30: Current controller in voltage limiting.
40: At least one identification contains errors. The 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 induc-
tance.
102, 104: Voltage limiting while measuring the inductance.
103: Maximum frequency exceeded during the 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 the 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 accel-
erating 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 emulation 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 system in p7003. If, for power units connected in paral-
lel, a motor is specified with a single-winding system (p7003 = 0), although a multi-winding system is
being used, then a large proportion of the stator resistance 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.
