Danfoss VLT Flow Drive FC 111 User Manual

•
Table 255: Option:
[0]
Off
Select [0] Off only if the drive is fed by an isolated mains source (IT mains). In this mode, the internal RFI filter capaci-
tors between chassis and the mains RFI filter circuit are cut out to reduce the ground capacity currents.
[1]
On
Select [1] On to ensure that the drive complies with EMC standards.
14-51 DC-Link Voltage Compensation
Default value: [1] On
Parameter type: Option
2-setup: All setups
Conversion index: -
Data type: u_int8
Change during operation: False
Enable the DC-link compensation to reduce ripple in the DC-link voltage (recommended for most applications).
Table 256: Option:

14-52 Fan Control
Default value: [0] Auto
Parameter type: Option
2-setup: 1 setup
Conversion index: -
Data type: u_int8
Change during operation: True
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 257: 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. This is the default
setting for all drives except H1 enclosure sizes.
[4]
Auto Low Temp
Env.
Only valid for H6-H8 enclosure sizes.
[5]
Constant-on
mode
For on-site fan test or if the fan must run 100% speed constantly. Only valid for H1- H5 enclosure sizes.
[6]
Constant-off
mode
If convection cooling is sufficient or if 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 H1-H5 enclosure sizes.
[7]
On-when-Inver-
ter-is-on-else-
off Mode
The fan runs at maximum speed if in hand-on mode or reference is above 0 Hz. The fan is stopped if sleep
mode is active. This is the default setting for H1 enclosure size only but can also be selected for H2-H5
enclosure sizes.
14-53 Fan Monitor
Default value: [1] Warning
Parameter type: Option
2-setup: 1 setup
Conversion index: -
Data type: u_int8
Change during operation: True
Select which reaction the drive should take in case a fan fault is detected. This parameter is only valid for drives of the following
enclosure sizes:
IP20, 3x380–480 V, enclosure sizes H6–H8.
