Heatsink
The heatsink fins accumulate dust from the cooling air. Since a dusty heatsink is less
efficient at cooling the drive, overtemperature faults become more likely. In a
“normal” environment (not dusty, not clean) check the heatsink annually, in a dusty
environment check more often.
Clean the heatsink as follows (when necessary):
1. Remove power from drive. Wait 5 minutes and measure to confirm.
2. Remove the cooling fan(s) (see section Main cooling fan replacement below).
3. Blow clean, dry, oil-free condensed air (not humid) from bottom to top and
simultaneously use a vacuum cleaner at the air outlet to trap the dust.
Note: If there is a risk of the dust entering adjoining equipment, perform the cleaning
in another room.
4. Replace the cooling fan(s).
5. Restore power.
Main cooling fan replacement
Main cooling fans are speed-controlled, and the speed of the fan matches the
cooling needs. When the drive is stopped, the main fan is kept running at a low
speed to cool the control board. Replacement fans are available from ABB. Do not
use other than ABB specified spare parts.
Frame Size R1...R3
To replace the fan:
WARNING! Obey the Safety instructions on page 2. Ignoring the instructions can
cause physical injury or death, or damage to the equipment.
1. Stop the drive and disconnect it from the power line. Wait for 5 minutes and then
make sure by measuring that there is no voltage. See section
Precautions before
electrical work on page 3 before you start the work.
2. Pry the fan assembly off the drive frame with a screwdriver (2a) and pull out of the
fan assembly (2b) until you can unplug the fan power supply wires from the fan
assembly (2c).
3. Install the fan assembly in reverse order.
R1…R2: Put the connector and extra length of wires in the groove so that the wires
do not get caught in the revolving fan.
R3: Put the extra length of wires under the fan assembly so that the wires do not get
caught in the revolving fan.
4. Restore power.
