Programming Guide
Option Name Description
[0] Off Disables DC-link compensation.
[1]* On Enables DC-link compensation.
[2] Advanced Improved compensation of DC-link ripple caused by mains frequency and phase imbalance.

14-52 Fan Control
Default value: [0] Auto
Conversion index: -
Select the minimum speed of the main fan.
Op- Name Description
tion
[0]* Auto
Select [0] Auto to run fan only when internal temperature in the drive is in the range 35 °C (95 °F) to ap-
proximately 55 °C (131 °F). The fan runs at low speed below 35 °C (95 °F), and at full speed at approxi-
mately 55 °C (131 °F).
[1] On 50% The fan always runs at 50% speed or above. The fan runs at 50% speed at 35 °C (95 °F), and at full speed at
approximately 55 °C (131 °F).
[2] On 75% The fan always runs at 75% speed or above. The fan runs at 75% speed at 35 °C (95 °F), and at full speed at
approximately 55 °C (131 °F).
[3] On 100% The fan always runs at 100% speed.
[4] Auto (Low
This option is the same as [0] Auto, but with special considerations around and below 0 °C (32 °F). In op-
temp env.)
tion [0] Auto there is a risk that the fan starts running around 0 °C as the drive detects a sensor fault and
thus protects the drive while reporting warning 66, Heat sink Temperature Low. Option [4] Auto (Low temp
env.) can be used in very cold environments and prevents the negative effects of this further cooling and
avoids warning 66, Heat sink Temperature Low.
