Parameter Descriptions
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:
0 [-2147483647 - 2147483647]
*
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 F-40 Torque Limiter
(Driving) and F-41 Torque Limiter (Braking).
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:
1.0 ms [1 - 100 ms]
*
SP-35 Stall Protection
Option: Function:
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.
AF-650 GP Programming Guide
Function:
For internal service only.
Function:
DET-618C
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:
NOTE
66 % [40 - 90
*
%]
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 - The Cos(phi) setpoint is automatically set for
*
0.95] 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.
