Parameter Descriptions
SP-32 Current Lim Ctrl, Filter Time
Range:
Function:
hardware limit for current. However, the
control reacts slower as it does not react on
immediate values.
SP-35 Stall Protection
Option:
Function:
Parameter SP-35 Stall Protection is active in flux
mode only.
[0]
Disabled Disables stall protection in field weakening flux
mode and might cause the motor to be lost.
[1]
Enabled Enables stall protection in field weakening flux
*
mode.
SP-36 Fieldweakening Function
Select the field weakening function mode in flux mode.
Range:
Function:
0
[Auto] In this mode, the frequency converter calculates the
*
optimal torque output.
Measured DC-link voltage determines the phase-to-
phase motor voltage. Magnetising reference is
based on the actual voltage and utilises the
information about the model of the motor.
1
[1/x]
The frequency converter reduces torque output.
The frequency converter sets the magnetising
reference inversely proportional to the speed using
a static curve that shows the relationship between
DC-link voltage and the speed.
SP-37 Fieldweakening Speed
Range:
1420 RPM
[10 - 60000 RPM]

3.9.4 SP-4# Energy Savings
Parameters to configure the energy optimization level in
both the Variable Torque and Energy Savings modes.
SP-40 VT Level
Range:
Function:

90 %]
*
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
[40 -
This parameter is not active when
parameter P-20 Motor Construction is set
to [1] PM non-salient SPM.
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
[5 - 40
Hz]
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:
[0.40 -
The Cos(phi) setpoint is automatically set for
optimum Automatic Energy Savings
performance. This parameter should normally
not be altered. However, in some situations it
may be necessary to enter a new value to fine-
tune.
