Configurable points are inputs and outputs that let you read and write
parameter values. These objects handle only 15-bit parameter values
(0 – 32767).

Important: If a parameter has a decimal point, the value must be

properly scaled by the user. For example, Accel Time has
two decimal places. To use the value 60.00, the scaled value
6000 must be communicated to the drive. The scaled value
6000 will be returned.

Reading Parameter Values

The configurable points may show any parameter in the drive by
configuring the Param# in the Read Param point. The drive reads the
value of the parameter configured in the Param# for the Read Param
point and shows the result in the Read Value point. The Param# for the
Read Param point default to commonly accessed parameters and can be
changed if desired. A “0” disables the fetching of data and a “0” is
returned in the Read Value point. See
