346 Control through a fieldbus adapter
Fieldbus references
References (FBA REF) are 16/32-bit signed integers. A negative reference
(indicating reversed direction of rotation) is formed by calculating the two’s
complement from the corresponding positive reference value. The contents of each
reference word can be used as torque or speed reference.
When torque or speed reference scaling is selected (by parameter
), the fieldbus references are 32-bit integers. The
value consists of a 16-bit integer value and a 16-bit fractional value. The
speed/torque reference scaling is as follows:
Reference
Scaling
Notes
Speed reference
FBA REF / 65536
(value in rpm)
Final reference is limited by parameters
and
Torque reference
FBA REF / 65536
(value in %)
Final reference is limited by torque limit
parameters
