Defining current and speed limits
Limitation of the speed setpoint
Parameterising the reference speed in
C00011
means that the drive must rotate at the set
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
Info
Lenze setting
Value Unit
C00909/1
Max. positive speed
120 %
C00909/2
Max. negative speed
120 %
C00910/1
Max. positive output frequency
1000 Hz
C00910/2
Max. negative output frequency
1000 Hz
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
).
