Description
See selection AI1.
See selection AI1.
Limit given with 20.19
Defines the minimum torque limit 1 for the drive.
Value of limit in percent of motor nominal torque.
Defines the minimum torque limit 2 for the drive.
Value of limit in percent of motor nominal torque
Defines the maximum torque limit 2 for the drive.
Value of limit in percent of motor nominal torque.
Defines the source or constant for value Par.
Parameter index or a constant value.
Defines the source or constant for value Par.
Parameter index or a constant value. See parameter
the difference. FbEq for the torque value is 100 = 1%.
Defines how an analogue signal (mA or V) is converted to a torque minimum or
maximum limit (%). The figure below illustrates converting when analogue
input AI1 has been set the source for a torque limit with parameter
20.14.
