Parameter
Notes
P1.2.9.7
1305
Window negative “window neg”
Defines the size of window to negative direction from the final speed reference.
If both windows off limits are zero this parameter is also the speed limit from the
“FinalFreqRef”. Otherwise this is the speed control activation limit.
P1.2.9.8
1304
Window positive “window pos”
Defines the size of window to positive direction from the final speed reference.
If both windows off limits are zero this parameter is also the speed limit from the
“FinalFreqRef”. Otherwise this is the speed control activation limit.
P1.2.9.9
1307
Window negative off limit “window neg off”
Defines the speed controller negative off limit when the speed controller brings the
speed back to window.
P1.2.9.10
1306
Window positive off limit “window pos off”
Defines speed controller positive off limit when speed controller brings speed back to
window.
P1.2.9.11
1253
Torque step “torque step”
9000xDrive parameter to help adjusting the torque controller (see 9000xDrive Tools:
Step Response). With this tool you can give step to torque reference.

Notes
P1.2.9.11.1
636
Open loop torque control minimum frequency “OL TC min freq”
Defines the frequency limit below which the frequency converter operates in frequency
control mode.
P1.2.9.11.2
639
Open loop torque controller P gain “OL TorqCtrl P”
Defines the gain for open loop torque control.
P1.2.9.11.3
640
Open loop torque controller I gain “OL TorqCtrl I”
Defines the integration gain for open loop torque control.

Notes
P1.2.10.1
509
Prohibit frequency area 1; low limit “range 1 low lim”
P1.2.10.2
510
Prohibit frequency area 1; high limit “range 1 high lim”
Range definition where a different ramp time defined by “RampTimeFactor” is used.
5.2.4.1 Torque reference OL settings
5.2.5 Prohibited frequencies
In some systems it may be necessary to avoid certain
frequencies because of mechanical resonance problems.
With these parameters it is possible to set limits for the
prohibited frequency region and ramp rate factor to use
when frequency is going above this area. When the input
reference is increased the internal reference is kept at the
low limit until the input reference is above the high limit.
