606.x DC voltage too high
Description
This error is triggered as soon as the measured DC link voltage of the PULSAR exceeds the peak input voltage by 100 V or exceeds the absolute value of 800 VDC.
Remedy
Voltage of power input greater than 560 VAC
- Reduce line voltage.
Neutral three-phase supply with 0 VDC PULSAR connected
- Remove neutral connection to 0 VDC.
- Wire neutral connection to 0 VDC via choke coil.
Output line PULSAR X103:1 or X103:2 is short-circuited against machine ground (welding transformer has short circuit against ground).
- Eliminate short circuit.
Drives feed too powerfully back into the link when braking.
- Reduce speed.
