ABB ACS 160 - P Loadability of ACS 160

18 ACS 160 User’s Manual
P Loadability of ACS 160
Motor mounted ACS 160 types are primarily cooled by the air flow caused by the axial fan of the
motor. Cooling performance of the ACS 160 is therefore dependent on the motor type and the
speed at which the motor is rotating. Wall mounted ACS 160 types have a fan unit to provide
constant cooling air flow for the converter
See section Q for continuous output current (I
2N
) ratings.
• Loadability of the ACS 160 is 150 % * I
2N
for 1 minute every 10 minutes.
• At starting, the loadability of the ACS 160 is 180 % * I
2N
for 2 seconds.
In the event of overload, the ACS 160 will first indicate an alarm and then trip. Parameter 0110
ACS
TEMP can be used to monitor the power module temperature.
Note! The motor should not be continuously supplied with current that is greater than the nominal
current of the motor.
Normal temperature range of the ACS 160 is up to 40
°C (104 °F). With derating, using converter in
up to 50
°C (122 °F) ambient is possible. Observe torque derating curves below (T/T
N
, %).
Note! The entire converter enclosure forms a cooling surface to dissipate surplus heat. Painting the
converter is therefore not allowed.
If the ACS 160 drive is attached on top of motors other than specified, the allowed continuous
torque ratings must be verified by thermal tests. Contact your local ABB representative for more
information.
