Function
This parameter sets the heatsink threshold for the activation of its cooling fans
according to the control logic set in C264a.
This parameter is active only if C264a=0: Default or 2: By Temperature Only.
The real temperature of the heatsink can be displayed in measure parameter M064.

Function
This parameter defines the control logic of the heatsink cooling fans.
0: [Default]: The heatsink cooling fans are on whenever the drive is enabled (and
IGBTs are switching)
; when the drive is disabled, fans are off only if the heatsink
temperature drops below C264.
1: [Always On]: Fans are always on.
2: [By Temperature Only]:
Fans are on only if the heatsink temperature is higher than
the value set in C264, regardless of the drive status.
NOTE
Parameters C264 and C264a take effect only for the Penta models where fans are
controlled directly by the drive control board (F
), as displayed on the Product screen in
the PRODUCT MENU. See Table 17 and Table 18.
