US - Basic Setup Parameters
Serial Binary Speed DIN66019, Service 50
RS485 serial communication DIN66019, Service 50 protocol includes 1x32-
bit, 2x16-bit Process Data Inputs and a 1x32-bit AUX R/W. The Process Data
Inputs are then mapped to the corresponding functions: Field Bus Speed,
Control Word, Pretorque, Position. The serial communication is connected to
the keypad operator terminal port X6C. The High Speed must be set in LS02.
The speed selection for Serial Binary Speed is done through the control-word
bits 4, 5, and 6 (Bin. Speed 1 - Bin. Speed 3). The input logic table can be
defined in LI03 Speed Input Decoding and or LI16 Custom Input Decoding as
to which corresponding speed in the LS parameter group is selected.
The speed profile between selected speeds will be internally generated by the
drive according to the programmed acceleration, deceleration and jerk rates
in the LS parameters group.
The direction is determined by the selected direction. Either a hardware or
software direction input can be utilized. 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) and 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. Both direction signals 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.
