SP-26 Trip Delay at Drive Fault
Range:
Function:
If value = 0,
protection mode
is disabled
NOTE
It is recommended to disable
protection
mode
in hoisting applications.
SP-29 Service Code
Range:
Function:
0
*
[-2147483647 - 2147483647]
For internal service only.
3.9.3 SP-3# Current Limit Ctrl.
Parameters to configure the Current Limit Control which is
activated when the motor current, and thus the torque, is
higher than the torque limits set in
SP-30 Current Lim Ctrl, Proportional Gain
Range:
Function:
100 %
*
[0 - 500 %] Enter the proportional gain value for the
current limit controller. Selection of a high
value makes the controller react faster. Too
high a setting leads to controller
instability.
SP-31 Current Lim Ctrl, Integration Time
Range:
Function:
0.020 s
*
[0.002 - 2 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.
SP-32 Current Lim Ctrl, Filter Time
Range:
Function:
1.0 ms
*
[1 - 100 ms]
SP-35 Stall Protection
Option:
Function:
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.
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:
66 %
*
[40 - 90
%]
NOTE
This parameter cannot be adjusted while
the motor is running.
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.
NOTE
This parameter is not active when
P-20 Motor Construction
is set to
[1] PM non salient SPM
.
SP-41 Energy Savings Min. Magnetization
Range:
Function:
40 %
*
[40 - 75 %] Enter the minimum allowable magnetisation
for Automatic Energy Savings. Selection of a
low value reduces energy loss in the motor,
but can also reduce resistance to sudden
load changes.
NOTE
This parameter is not active when
P-20 Motor Construction
is set to
[1] PM non salient SPM
.
SP-42 Energy Savings Min. Frequency
Range:
Function:
10 Hz
*
[5 - 40 Hz] Enter the minimum frequency at which the
Automatic Energy Savings is to be active.
NOTE
This parameter is not active when
P-20 Motor Construction
is set to
[1] PM non salient SPM
.
SP-43 Motor Cosphi
Range:
Function:
0.66
*
[0.40 -
0.95]
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.
