Enables/disables the square root function for each user-configurable analog

input.

of I/O hardware that is present on this drive and is controlled by the inverter.

This function should be enabled if the input signal varies with the square of the

quantity (for example, drive speed) being monitored. The square root function is

scaled such that the input range is the same as the output range. For example, if

the input is set up as a unipolar voltage input, then the input and output ranges of

the square root function are 0...10 volts.

The drive scales the value read from the user-configurable analog input and

converts it to units usable for the application. You control the scaling by setting

parameters that associate a low and high point in the input range with a low and

high point in the target range.

Analog In 1 Hi sets the highest input value to the user-configurable analog input
