3.4.12.3
External cooling for braking resistors
A digital output and a digital input can be used to control and monitor an external cooling fan
or pump for the braking resistors.
3.4.12.4
Braking chopper ratings
The maximum braking power is limited to 60% of the nominal power of the ACS1000 and must
not be greater than 2.5 MW (Tab. 2-1).
The relation between maximum braking energy (E
brake max
) and maximum chopper braking
power (P
chopper max
) is as follows:
After a braking period of 30 s with maximum braking power (2.5 MW), a cooling time of one
hour is required. If two braking sequences of 30 s are necessary within an hour, the maximum
braking power has to be reduced to 50% of the maximum possible braking power.
