Function
Heatsink temperature for current decrease.
If set to “0”, this function is disabled.
The current heatsink temperature may be displayed in measure
M064
(see section 2.5.5).
If the detected temperature exceeds the preset value, the nominal current is reduced by a given
percentage per extra degree equal to the value set in parameter
C810
.
The typical effect of current decrease is a slower motor speed of rotation.

Function
If the temperature detected on the heatsink (measure
M064
) is higher than the value set in
C809
, the
nominal current is reduced by a given percentage per extra degree equal to the value set in this
parameter.
NOTE
If the motor speed drops below the value set in parameter C800 due to current decrease for
overtemperature, alarm A074
– Overload (see section 2.7.3) trips after a timeout set in
parameters P018, P019 (see section 2.6.1).
