Programming Guide
14-52 Fan Control
Default value: [0] Auto
Conversion index: -
This parameter is used to select the fan control operating mode. The acoustic noise of the drive is different from running heavy load
(high heat sink temperature) to running light load or stand-by mode.
Table 253: Option:
[0]
Auto
The fan runs with full speed for a short time and then automatically adjusts the speed according to the
load and ambient temperature. The fan also runs at minimum speed even if the reference is 0 Hz due to
the heat generated from the IGBT. The fan stops if sleep mode function is activated.

Auto Low Temp
Only valid for I6-I8 enclosure sizes.
Env.

Constant-on
For on-site fan test or if the fan must run 100% speed constantly. Only valid for I2-I4 enclosure sizes.

Constant-off
If convection cooling is sufficient or the drive is mounted in a demonstration panel, exhibitions and so

on. The drive trips on heat sink overtemperature if loaded more than the convection cooling allows. Only
valid for I2-I4 enclosure sizes.

On-when-Inver-
The fan runs at maximum speed if in hand-on mode or reference is above 0 Hz. The fan is stopped if
ter-is-on-else-off
sleep mode is active. This is the default setting for H1 enclosure size only but can also be selected for I2-
