The controller will have a set of parameters with which the Performance Table can be set up. The table consists of three
speed settings and three current settings:
•
Maximum drive current (“ImotMax” in Autotune Menu)
•
Performance Table Speed 1 (7.9)
•
Performance Table Speed 2 (7.10)
•
Performance Table Speed 3 (7.11)
•
Percentage of the maximum drive current at speed 1 (7.12)
•
Percentage of the maximum drive current at speed 2 (7.13)
•
Percentage of the maximum drive current at speed 3 (7.14)
Note
that the maximum current corresponding to 100% of Performance table cutback is specified by the maximum current
in the Autotuning menu
(
M4-9 Maximum RMS motor current
).
Note
that the performance table speed are percentage of maximum speed expressed in Autotune Menu
.
For example if 4.10 is 200 Hz and the desired three Performance table speeds are: Speed 1 50Hz, Speed2 130 Hz and
Speed3 185Hz set PTSpeed 1 to 25% (50x100%/200) Speed2 to 65% (130x100%/200) and Speed 3 to 92% (185*100%/200)
The limit will run from 100 % (no cut back) to 0 % (full cut back). This is displayed
also in the Status Menu at “Drive
Availability”.
When the Performance Table is actually limiting the current with respect to the drive speed, the Status menu will show
‘PT’ limit indication
.
Failure messages related to performance table
F7 S709 is the failure code related to performance table. It happens when performance table is being set not in the correct
order. When finish to set up the performance table recycle the key. If F7 S709 is there it means that in the Performance
table settings are not consistent.
Here the situations that gives F7 S709:
•
if Performance Table Cutback 1 is lower than Performance Table Cutback 2 or Performance Table Cutback 2 is
lower than Performance Table Cutback 3.
•
it is also related to the performance table Speed 1, 2,3. In fact for a proper setting to avoid F07 S709 Speed1
must be lower than Speed 2 and Speed 2 must be lower than Speed 3
To solve F7 S709 make sure that Performance Table Cutback 1 is greater than Performance Table Cutback 2 and
Performance Table Cutback 2 is greater than Performance Table Cutback 3. Furthermore check that Performance Table
Speed 1 is lower than Performance Table Speed 2 and Performance Table Speed 2 is lower than Performance Table Speed
3.
Interaction with Other limits
The controller may have other limits in effect (e.g. controller temperature limit or high voltage limit). The module which
is limiting the most, will apply the limit. The ‘drive availability’ will then show the limit of the corresponding module.
Example
•
Controller temperature limit
50 %
•
Performance Table
80 %
•
Applicable limit
→
50 %
•
Applicable module
→
Controller temperature (indicated by ‘CT’).
Interaction with Motor Module performance table
The motor module current reduction map in field weakening is reducing current as a function of the speed too. See
settings 5.14 to 5.18. It means that the lower value for current limiting between the Performance table and motor module
current reduction map is applied.
