A B C D E F G H I Possible cause Remedy
✘
- - - - - - - - No voltage Check mains fuses, mains voltage and
operating status of the frequency
inverter
✘ - - - - - - - - Phase failure in frequency inverter Check phase and reinsert fuse if required
✘ - - - - - - - - Mains cables connected incorrectly/
Fault in supply line
Check wiring
✘ - - - - - - - - Mains fuse rating too small for frequency
inverter input current
Observe connected loads from the
project planning information for the
frequency inverter and observe
VDE 0100 requirements.
✘
- - - - - - - - Permissible voltage range undershot/
exceeded
Check output voltage of frequency
inverter and operate drive using
required voltage.
✘ - - - - - - - - No enable Insert bridge in frequency inverter/
safeguard enable via field bus.
✘
- - - - - - - - No setpoint signal (internal/external) Check setpoint signal (internal/external);
setpoint must exceed actual value.
✘
- - - - - - - - Sensor (signal) fault Check sensor and sensor cable.
✘
- - - - - - - - Short circuit on control cables Check/replace the control cables/
connections.
✘ - - - - - - - - 24 V supply overloaded De-energise drive and rectify overload in
24 V supply circuit.
✘ ✘ - - - - - - - Driven machine is blocked Manually clear the blockage from the
driven machine, observe the instructions
in the operating manual of the driven
machine.
- ✘ ✘ - - - - - - Standard behaviour of control algorithm High-frequency humming noise emitted
at up to 50 percent of the nominal speed
is part of the standard behaviour of the
drive.
