NOTE

Automatic reset will also be active for resetting safe stop

function.

14-21 Automatic Restart Time

Range: Function:

10.0 s* [0.0 - 600.0 s] Enter the time interval from trip to start of

the automatic reset function. This

parameter is active when 14-20 Reset Mode

is set to Automatic reset [1] - [13].

14-22 Operation Mode

Option: Function:

Select Initialisation[2] to reset all parameter

values to default.

[0] * Normal

operation

Select Normal operation [0] for normal

operation of the frequency converter with the

motor in the selected application.

[2] Initialisation

Select Initialisation [2] to reset all parameter

values to default settings, except for

15-03 Power Up's, 15-04 Over Temp's and

15-05 Over Volt's. The frequency converter will

reset during the next power-up.

14-22 Operation Mode will also revert to the

default setting Normal operation [0].

14-27 Action At Inverter Fault

Option: Function:

Select how the frequency converter should react at

inverter fault. Action At Inverter Fault

[0] Trip

[1] * Warning

3.10.4 14-4*Energy Optimising

Parameters for adjusting the energy optimisation level in

both Variable Torque (VT) and Automatic Energy Optimi-

zation (AEO) mode.

Automatic Energy Optimization is only active if 1-03 Torque

Characteristics, is set for Auto Energy Optim. [3].

14-40 VT Level

Range: Function:

90 %* [40 - 90

Enter the level of motor magnetisation at low

speed. Selection of a low value reduces energy

loss in the motor, but also reduces load

capability.

This parameter cannot be adjusted while the

motor is running.

14-41 AEO Minimum Magnetisation

Range: Function:

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

for AEO. Selection of a low value reduces

energy loss in the motor, but can also reduce

resistance to sudden load changes.

3.10.5 14-5* Environment

These parameters help the frequency converter to operate

under special environmental conditions.

14-50 RFI Filter

Option: Function:

[0] Off

Select Off [0] only if the frequency converter is fed by an

isolated mains source (IT mains).

In this mode, the internal RFI filter capacitors between

chassis and the mains RFI filter circuit are cut-out to

reduce the ground capacity currents.

[1] * On

Select On [1] to ensure that the frequency converter

complies with EMC standards.

14-51 DC-Link Voltage Compensation

Option: Function:

[0] Off Disables DC Link Compensation.

[1] * On Enables DC Link Compensation.

14-52 Fan Control

Option: Function:

Only valid for the following frequency

converters: 380-480V, 30-90kW.

[0] * Auto

[4] Auto Low Temp Env.

14-53 Fan Monitor

Option: Function:

Select which reaction the frequency converter

should take in case a fan fault is detected. (Only

valid for some drive sizes.)

[0] Disabled

[1] * Warning

[2] Trip

14-55 Output Filter

Option: Function:

Select wether a output filter

is present.

[0] * No Filter

[1] Sine-Wave Filter

[3] Sine-Wave Filter with Feedback
