Serial Speed DIN66019, Service 49
RS485 serial communication DIN66019, Service 49 protocol includes 4x16-
bit Process Data Inputs. The Process Data Inputs are then mapped to the
corresponding functions: Field Bus Speed, Control Word, Pretorque, Position.
The serial communication connected to the keypad operator terminal port X6C
controls the speed via the Process Data Input assigned as Field Bus Speed.
The High Speed must be set in LS02.
The speed pro file acceleration, deceleration and jerk rates are externally
generated by the controller. It is possible to limit external profile rates by setting
LS15 = Internal Profile (4) and adjusting the according LS20-25 High Speed
profile rates.
The direction is determined by the sign of the Field Bus Speed, although a
direction is needed to control the start and stop routines. Either a hardware
or software direction input can be utilized. Either or both Up and Down inputs
can be used for direction but the direction selected does not matter since the
actual direction is determined by the sign of the Field Bus Speed. Software
directions can be controlled via direction bits in the Process Data Input assigned
as Control Word or assigned to software inputs Fb21-27 as Up (25) or Down
(26) Direction and controlled via the Control Word. Hardware digital inputs
can be assigned in LI04-11 as Up (25) or Down (26). If both software Control
Word direction and hardware direction inputs are used, LI15 Direction Selection
Inputs determines whether they are OR (0: Up and Down Inputs) or AND (2:
Up & Down AND Serial Control Word) activated; if a software input is assigned
as direction (as opposed to the Control Word direction bits), the hardware and
software inputs are OR activated. If both hardware and software direction inputs
are used, the selected direction must match. If both Up and Down directions
are used, they cannot be signaled simultaneously at the beginning of a run,
otherwise ‘Direction Selection Failure’ will occur.
The Drive Enable is AND activated by the Control Word and hardware input I7.
Refer to Section 6.15 for additional information regarding Field Bus
parameters and serial communication.
