Ambient conditions
For the environmental limits for the safety functions and the drive, refer to the hardware
manual of your drive.
￭
ACS880-07 drives, frames R6 to R11
The maximum ambient temperature for the drive with safety relays is 45 °C (113 °F). In the
temperature range +40…45 °C (+104…113 °F), the rated output current must be derated
by 2% for every added 1 °C (1.8 °F). The output current can be calculated by multiplying
the current given in the rating table by the derating factor (
k
):
