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 parallel, a motor is
specified with a single-winding system (p7003 = 0), although a multi-winding system is being used, then a large pro-
portion 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 has been correctly connected (star-delta).
Re fault value = 50:
- reduce the current controller sampling rate.
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 have 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 = 115:
- de-select V/f control (p1317 = 0).
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 = 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, moment 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 inertia, parameterize the load moment of inertia (p1498).
- reduce the ramp-up time (p1958).
- increase speed controller P-gain (p1460).
- suppress meas. (p1959).
