Illustration 101: Speed Controller Adaptive Gain
10.627.1 (ID 1295) Speed Controller Torque Minimum Gain
Location in the menu:
P2.6.15.30
(Multi-purpose Control Application)
Use this parameter to set the relative gain in percentage when the torque is below SPC Torque Minimum.
The relative gain as a percentage of
ID 613
of the speed controller when the torque reference or the speed control output is less
than the value of parameter
ID 1296
. This parameter is normally used to stabilize the speed controller for a drive system with gear
backlash.
10.627.2 (ID 1296) Speed Controller Torque Minimum
Location in the menu:
P2.6.15.29
(Multi-purpose Control Application)
Use this parameter to set the limit for the reduced speed controller gain.
The level of torque reference below which the speed controller gain is changed from
ID 613
to
ID 1295
. It is in percentage of motor
nominal torque. The change is filtered according to parameter
ID 1297
.
10.627.3 (ID 1297) Speed Controller Torque Minimum Filtering Time
Location in the menu:
P2.6.15.31
(Multi-purpose Control Application)
Use this parameter to set the filtering time for speed controller gain.
Filtering time for torque when the speed controller gain is changed between
ID 613
and
ID 1295
depending on
ID 1296
.
10.627.4 (ID 1298) Speed Controller Gain in Field Weakening Area
Location in the menu:
P2.6.15.28
(Multi-purpose Control Application)
Use this parameter to set the final gain for speed controller gain at field weakening point.
The relative gain of the speed controller in the field weakening area as a percentage of parameter
ID 613
.
10.627.5 (ID 1299) Speed Controller Gain F0
Location in the menu:
P2.6.15.27
(Multi-purpose Control Application)
Use this parameter to set the relative gain in percentage below the speed controller F0 point.
The relative gain of the speed controller as a percentage of parameter
ID 613
when the speed is below the level defined by
ID 1300
.
