3.10.5 14-4* Energy Optimization

Parameters for adjusting the energy optimization level in

both variable torque (VT) and automatic energy optimi-

zation (AEO) mode.

Automatic energy optimization is only active if

parameter 1-03 Torque Characteristics is set to [3] Auto

Energy Optim.

14-40 VT Level

Range: Function:

90 %* [40 -

90 %]

NOTICE

This parameter cannot be adjusted

while the motor is running.

Enter the level of motor magnetization at low

speed. Low values reduce energy loss in the

motor, but also reduce load capability.

14-41 AEO Minimum Magnetisation

Range: Function:

66 %* [40 - 75 %] Enter the minimum allowable magnetization

for AEO. Low values reduce energy loss in

the motor, but also reduce resistance to

sudden load changes.

14-44 d-axis current optimization for IPM

Range: Function:

100 %* [0 - 200 %]

3.10.6 14-5* Environment

These parameters help the frequency converter to operate

under special environmental conditions.

14-50 RFI Filter

This parameter is only valid for frequency converters of the

following enclosure sizes:

•

IP20, 3x200–240 V, enclosure sizes H6–H8

•

IP20, 3x380–480 V, enclosure sizes H6–H8

•

IP54, 3x380–480 V, enclosure sizes I6–I8

•

IP20, 3x525–600 V, enclosure sizes H6–H10

Option: Function:

[0] O Select [0] O only if the frequency converter is fed by

an isolated mains source (IT mains).

In this mode, the internal RFI lter capacitors between

chassis and the mains RFI lter circuit are cut out to

reduce the ground capacity currents.

[1] * On Select [1] On to ensure that the frequency converter

complies with EMC standards.

14-51 DC-Link Voltage Compensation

Option: Function:

[0] O The overmodulation for output voltage is o to avoid

torque ripple on the motor shaft.

[1] * On Enables the overmodulation for output voltage to

obtain an output voltage up to 15% greater than the

mains voltage.

14-52 Fan Control

This parameter is used to select the fan control operating mode.

The acoustic noise of the frequency converter is dierent from

running heavy load (high heat sink temperature) to running light

load or stand-by mode.

Option: Function:

[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 frequency

converters except H1 enclosure sizes.

[4] Auto Low Temp

Env.

Only valid for H6-H10 & I6-I8 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 & I2-I4 enclosure sizes.

[6] Constant-o

mode

If convection cooling is sucient or the

frequency converter is mounted in a

demonstration panel, exhibitions and so on.

The frequency converter trips on heat sink

overtemperature if loaded more than the

convection cooling allows. Only valid for

H1-H5 & I2-I4 enclosure sizes.

[7] On-when-

Inverter-is-on-

else-o 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 &

I2-I4 enclosure sizes.

14-53 Fan Monitor

Select which reaction the frequency converter should take in

case a fan fault is detected. This parameter is only valid for

frequency converters of the following enclosure sizes:

•

IP20, 3x200–240 V, enclosure sizes H6–H8.

•

IP20, 3x380–480 V, enclosure sizes H6–H8.

•

IP54, 3x380–480 V, enclosure sizes I6–I8.

•

IP20, 3x525–600 V, enclosure sizes H6–H10.

Option: Function:

[0] Disabled

[1] * Warning

[2] Trip
