*
3 3
SP-31 Current Lim Ctrl, Integration Time
Range:
0.020 s [0.002 - 2 s] Controls the current limit control
*
SP-32 Current Lim Ctrl, Filter Time
Range:
26.0 ms [1 - 100 ms] Sets a time constant for the current limit

3.8.4 SP-4# Energy Savings
Parameters for adjusting the energy optimization level in
both variable torque (VT) and Energy Saving mode.
Energy Saving is only active if parameter H-43 Torque
Characteristics, is set for either [2] Energy Savings CT or [3]
Auto Energy Optim. VT.

Function:
current limit controller. Selection of a high
value makes the controller react faster. Too
high a setting leads to controller
instability.
Function:
integration time. Setting it to a lower
value makes it react faster. A setting too
low leads to control instability.
Function:
controller low-pass filter.
Function:
NOTICE
This parameter cannot be adjusted while
the motor is running.
NOTICE
This parameter is not active when
parameter P-20 Motor Construction is set to
[1] PM non-salient SPM.
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.
Function:
NOTICE
This parameter is not active when
parameter P-20 Motor Construction is set
to [1] PM non-salient SPM.
SP-41 Energy Savings Min. Magnetization

3.8.5 SP-5# Environment
NOTICE
Perform a power cycle after changing any of the
parameters in group 14-5* Environment.
These parameters help the frequency converter to operate
under special environmental conditions.
SP-50 RFI Filter
Option: Function:
[0] Off Select [0] Off if the frequency converter is fed by an
isolated mains source (IT mains).
If a filter is used, select [0] Off during charging to
prevent a high leakage current making the RCD
switch.
In this mode, the internal RFI filter capacitors between
enclosure and the mains RFI filter 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.

Function:
Enter the minimum allowable magnetization for
Automatic Energy Savings. Selection of a low
value reduces energy loss in the motor, but can
also reduce resistance to sudden load changes.
Function:
NOTICE
This parameter is not active when
parameter P-20 Motor Construction is
set to [1] PM non-salient SPM.
Enter the minimum frequency at which the
automatic energy Savings is to be active.
Function:
The Cos(phi) setpoint is automatically set for
optimum Energy Saving performance during
Auto Tune. This parameter should normally not
be altered. However, in some situations it may
be necessary to enter a new value to fine-tune.
