Fault rectification

The variable speed drive uses the following means to display faults and operating
states:
The LEDs on the front indicate the most important operating states.

The drive displays alarms and faults via the fieldbus, the terminal strip, a

connected operator panel, or via the STARTER software.
Alarms and faults have a unique number.

Restart after a crash

The drive can adopt the following state, for example, by loading a defective file
from the memory card:
 The motor is switched off.
 You cannot communicate with the drive, either via the operator panel or other
interfaces.
1. Remove the memory card if one is inserted in the converter.
2. Switch off the drive power supply.
3. Wait until all LEDs on the drive are extinguished.
4. Switch on the power supply again.
5. Repeat steps 2 to 4 until fault code F01018 is output.
6. Repeat steps 2 to 4 once again until fault code F01018 is output.
 The drive adopts the factory settings.
Repeat the commissioning process.


Displayed operating states

The Control Unit has two LEDs which indicate the operating state of the drive:
LED RDY = Ready

LED BF = Bus Fault

The LED RDY (Ready) is temporarily orange after the power supply voltage is
switched on. As soon as the color of the LED RDY changes to either red or green,
the LEDs signal the drive state.
In addition to the signal states "On" and "Off" there are two different flashing
frequencies:
2 s
