3.15.6 14-4* Energy Optimising
Parameters for adjusting the energy optimisation level in both Variable Torque (VT) and Automatic Energy Optimization (AEO) mode in par. 1-03 Torque
Characteristics
.
14-40 VT Level
Range: Function:
66 %* [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:
Application
dependent*
[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.
14-42 Minimum AEO Frequency
Range: Function:
10 Hz* [5 - 40 Hz] Enter the minimum frequency at which the Automatic Energy Optimisation (AEO) is to be active.
14-43 Motor Cosphi
Range: Function:
Application
dependent*
[0.40 - 0.95 ] The Cos(phi) setpoint is automatically set for optimum AEO performance. This parameter should
normally not be altered. However in some situations it may be necessary to enter a new value to
fine-tune.
3.15.7 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 Compensation
Option: Function:
[0] Off Disables DC Link Compensation.
[1] * On Enables DC Link Compensation.
14-52 Fan Control
Select minimum speed of the main fan.
Select
Auto [0] to run fan only when internal temperature in frequency converter is in range 35° C to approx. 55° C.
Fan runs at low speed below 35° C, and at full speed at approx. 55° C.
Option: Function:
[0] * Auto
[1] On 50%
[2] On 75%
[3] On 100%
