Overview of Alarms

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 = 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, 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).
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. routine while motor is still rotating.
Re fault value = 192:
- check closed-loop speed control (motor rotor may be locked or closed-loop speed control is not func-
tioning).
- for p1215 = 1, 3 (brake the same as the sequence control) check the control sense (p0410.0).
- ensure that enable signals are present during measurement.
- remove any pulling loads from motor.
- increase max. current (p0640).
