3.4.5
Technology module: Profibus
Support of PROFIBUS communication as per DP-V0. The functions as per PROFIDRIVE version 3.0 are available for the drive
applications. The features include functions as per Application Class 1 (speed and torque control) and Application Class 3
(point-to-point positioning).
In addition, it is also possible to integrate the device into a control system by I/O mapping via PROFIBUS. From a control point
of view, this option offers the same functionality as a standard PLC coupling via parallel wiring with regard to the digital I/Os of
the device.
A special item telegram can be used to access nearly all of the device-specific functions, exceeding the functionality defined by
PROFIDRIVE.
3.4.6
Technology module: EtherCAT
The EtherCAT interface enables the connection of the item servo positioning controller C Series to the EtherCAT fieldbus
system. The communication via the EtherCAT interface (IEEE-802.3u) is realised with the aid of EtherCAT standard cabling.
3.4.7
I/O functions and device control
Ten digital inputs provide the elementary control functions (see
chapter 4.6.6 I/O interface [
The item C Series has a target table in which the positioning targets can be stored and from where they can be retrieved at a
later point of time. At least four digital inputs are used for the target selection; one input is used as a start input.
The limit switches are used to limit the range of movement for reasons of safety. During homing, one of the two limit switches
can be used as a reference point for positioning control.
Two inputs are used for enabling the power output stage on the hardware side as well as for enabling the controller on the
software side.
High-speed sample inputs are available for various time-critical applications (e.g. homing, special applications).
The item servo positioning controller C Series has three analogue inputs for input levels in the range of +10 V to -10 V. One
input is a differential input (16 bits) to guarantee high interference immunity. Two inputs (10 bits) are single-ended inputs. The
analogue signals are quantised and digitalised by an analogue-digital converter with a resolution of 16 bits or 10 bits. The
analogue signals provide the setpoints (speed or torque) for the control.
In standard applications, the existing digital inputs are already used for basic functions. For further functions, e.g. the teach-in
mode, a separate "start homing" input, or a stop input, the analogue inputs AIN 1 and AIN 2 as well as the digital outputs
DOUT 2 and DOUT 3, which can also be used as digital inputs, are available.
