M5.5-1 Performance table speed 1 “PTSpd1”
M5.5-2 Performance table speed 2 “PTSpd2”
M5.5-3 Performance table speed 3 “PTSpd3”
M5.5-4 Performance table cutback 1 “PTCutBk1”
M5.5-5 Performance table cutback 2 “PTCutBk2”
M5.5-6 Performance table cutback 3 “PTCutBk3”
The Performance Table feature (setting from 5.5-1 to 5.5-6) is a Torque limiting feature: the maximum torque
is limited with increasing speed.
The Performance Table sets a specified percentage of the maximum Torque for a specified speed as shown in
the graph below. The Performance Table will only limit the drive torque/current, not the brake torque/current.
The brake torque/current is limited as the drive current for speed below the 5% of the maximum motor speed
that is expressed in the setting “FmotMax” in the Autotune menu.
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:
• Performance Table Speed 1 (5.5-1)
• Performance Table Speed 2 (5.5-2)
• Performance Table Speed 3 (5.5-3)
• Percentage of the maximum Torque at speed 1 (5.5-4)
• Percentage of the maximum Torque at speed 2 (5.5-5)
• Percentage of the maximum Torque at speed 3 (5.5-6)
Note that the performance table speed are percentage of ”Maximum motor frequency” (adjustable in “Menu 3
“Autotuning””) .
For example if Maximum motor frequency is 200 Hz and the desired three Performance table speeds are: Speed1
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)
