Parameter 4-12 Motor Speed Low Limit [Hz]
Table 225: Parameter 4-12 Motor Speed Low Limit [Hz]
4-12 Motor Speed Low Limit [Hz]
Default value: Size related
Parameter type: Range, 0 - par. 4-14 Hz
Setup: All setups
Conversion index: -1
Data type: Uint16
Change during operation: True
Enter the minimum limit for motor speed. The motor speed low limit can be set to correspond to the minimum output frequency of
the motor shaft. The motor speed low limit must not exceed the setting in
parameter 4-14 Motor Speed High Limit [Hz]
.
Parameter 4-13 Motor Speed High Limit [RPM]
Table 226: Parameter 4-13 Motor Speed High Limit [RPM]
4-13 Motor Speed High Limit [RPM]
Default value: Size related
Parameter type: Range, Par. 4-11 - 60000 RPM
Setup: All setups
Conversion index: 67
Data type: Uint16
Change during operation: True
Enter the maximum limit for motor speed. The motor speed high limit can be set to correspond to the manufacturer’s maximum
nominal motor speed. The motor speed high limit must exceed the setting in
parameter 4-11 Motor Speed Low Limit [RPM]
.
Parameter 4-14 Motor Speed High Limit [Hz]
Table 227: Parameter 4-14 Motor Speed High Limit [Hz]
4-14 Motor Speed High Limit [Hz]
Default value: Size related
Parameter type: Range, Par. 4-12 - Par. 4-19
Setup: All setups
Conversion index: -1
Data type: Uint16
Change during operation: True
Enter the maximum limit for motor speed in Hz.
Parameter 4-14 Motor Speed High Limit [Hz]
can be set to correspond to the manu-
facturer's recommended maximum motor speed. The motor speed high limit must exceed the value in
parameter 4-12 Motor Speed
Low Limit [Hz]
. The output frequency must not exceed 10% of the switching frequency (
parameter 14-01 Switching Frequency
).

N O T I C E
The torque limit reacts to the actual, non-filtered torque, including torque spikes. This is not the torque that is seen from the LCP
or the fieldbus as the torque is filtered.
This function limits the torque on the shaft to protect the mechanical installation.
