ABB ACS880 - Actual Values

￭ Actual values
The ABB Drives profile supports the use of two fieldbus actual values, ACT1 and ACT2.
The actual values are 16-bit words each containing a sign bit and a 15-bit integer. A
negative value is formed by calculating the two’s complement from the corresponding
positive value.
The actual values are scaled as defined by parameters 46.01...46.04; which scaling is
in use depends on the setting of parameters 58.28 EFB act1 type and 58.29 EFB act2
type (page 437).
