SCANMASKIN 28 WS, Manual

Page: 100 / 410

The machine is weak and
might stop when on the
ground.

One of the three phases are missing from
the power supply

There is a voltage drop at the power supply

Inspect the display on the inverter for any fault code

Inspect fuses inside electrical cabinet

Inspect the fuses in the worksites fuse box

Inspect cables

Measure that all three phases are present and at full
voltage at the cable end near the machine.

Make sure that the cable is not to long. If the cable
should be to long, use a cable with higher rating to a
distribution box nearer the machine.

Make sure that the cable is not too long. If
the cable should be too long, use a cable
with higher rating to a distribution box
nearer the machine

The environmental temperature is too
high. When the temperature is above
40°C (104°F) the inverter will decrease its
maximum output current

Inspect the ventilation fans

Inspect the filters to the fans
E07 Over voltage protection

DC bus voltage exceed a threshold

Inspect the power source
E08 EEPROM error

Built in EEPROM has problems due to
noise or excessive temperature.

Check the fans/ let the motor drive cool
down
