14-31 Current Lim Contr, Integration Time
Range: Function:
0.020 s* [0.002 - 2.000 s] Controls the current limit control integration time. Setting it to a lower
value makes it react faster. A setting too low leads to control instability.
14-32 Current Lim Ctrl, Filter Time
Range: Function:
26.0
ms*
[1.0 - 100.0 ms]
14-4*Energy Optimization
Parameters for adjusting the energy optimization level in both Variable Torque (VT) and Automatic Energy Op-
timization (AEO) mode.
Automatic Energy Optimization is only active if par.1-03
Torque Characteristics, is set for either Auto Energy
Optim. Compressor
[2] or Auto Energy Optim. VT [3].
14-40 VT Level
Range: Function:
66 %* [40 - 90 %] Enter the level of motor magnetization 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 Magnetization
Range: Function:
Applica-
tion de-
pend-
ent*
[40 - 75 %] Enter the minimum allowable magnetization 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 Optimiza-
tion (AEO) is to be active.
14-43 Motor Cos-Phi
Range: Function:
Applica-
tion de-
pend-
ent*
[0.40 - 0.95 N/A] The cos(phi) setpoint is automatically set for optimum AEO performance
during AMA. This parameter should normally not be altered. However,
in some situations it may be necessary to enter a new value to fine tune.
