Defining current and speed limits

5.3 Defining current and speed limits
Limitation of the speed setpoint
Parameterising the reference speed in
speed if a speed setpoint of 100% is specified.
All speed setpoint selections are provided in % and always refer to the reference speed set
in C00011.

Tip!
For reasons of achievable resolution and the accuracy involved, the reference
speed should be geared to the speed range required for the respective application.
Lenze recommendation: Reference speed (C00011) = 1500 ... 3000 rpm
Irrespective of the selected motor control, there are more limitation options:
Parameter
C00909/1
C00909/2
C00910/1
C00910/2

Note!
In the torque-controlled operation (bTorquemodeOn = TRUE), the limitation of
the speed setpoint does not have any effect! In this case, a permissible speed
range can be defined via speed limitation (nSpeedHighLimit and
nSpeedLowLimit).
