5.6 Serial Speed DIN66019, Service 50
RS485 serial communication DIN66019, Service 50 protocol includes 1x32-bit, 2x16-bit
Process Data Inputs and an 1x32-bit AUX R/W. The Process Data Inputs are then
mapped to the corresponding functions: Field Bus Speed, Control Word, Pre-torque,
Position.
The serial communication controls the speed via the Process Data Input assigned as
Field Bus Speed. The maximum high speed value must be set in parameter LS02 High
Speed.
The speed profile acceleration, deceleration and jerk rates are externally generated by
the controller. It is possible to allow the drive to generate the profiles 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 serial bus 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 serial bus 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 serial bus 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
l occur.
When setting the control word enable bit, it is still necessary to activate the STO and SBC
inputs on the safety module, terminal X2B, in order to enable operation.
5.7 Process Data Output Address
These are the mappings of diagnostic parameter hex addresses for Process Data Out.
For example, FB13 PDO1 = 1182h = DG02 Inverter Status. These parameters have the
same structure as FB17-20; refer to these parameters for further description.
All the DG parameters are defined as 32-bit parameters. However, most of them utilize a
range of only 16 bits. When assigning these 32-bit parameters to a 16-bit process data
container, the values will be cast to 16 bit. However, there are parameters which utilize
the full 32-bit range. With these parameters, it is necessary to take care when assigning
them to process data. Use of a 16-bit container will result in truncation of the value and
could result in change in polarity.
The following parameters utilize the full 32-bit range:
