Automatic reset will also be active for resetting safe stop
function.
14-21 Automatic Restart Time

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
, 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

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.
