Fault
Possible cause
Measure
Incorrect direction of ro-
tation
Incorrect setpoint polarity
Check frequency inverter,
check setpoints
Drive unit hums and has
high current consump-
tion
Drive is blocked
Check drive
Frequency inverter set in-
correctly
Check frequency inverter
Drive unit heats up ex-
cessively (measure tem-
perature, significantly
higher than 100 °C)
Overload
Measure power, use larger
drive unit or reduce load if
necessary, check travel
profile
Ambient temperature too
high
Observe permitted temper-
ature range
Insufficient cooling
Correct cooling air supply
or clear cooling air pas-
sages
Nominal duty type (S1 to
S10, EN 60034-1) ex-
ceeded, e.g. due to ex-
cessive effective torque
Adjust nominal duty type to
required operating condi-
tions; if necessary, call in a
specialist to determine the
correct drive
Frequency inverter not opti-
mized
Check frequency inverter
1) Short-term oil/grease leakage at the oil seal is possible in the run-in phase (24 hours runtime).
