3.4.2 UDP interface [X18]
The UDP communication enables the connection of the ARS 2000 SE series servo drives to the
Ethernet fieldbus system. The communication via the UDP interface [X18] is realised with the aid of a
standard cabling.
3.4.3 CAN interface [X4]
The CANopen protocol as per DS301 with application profile DSP402 is implemented.
The specific Metronix CAN protocol of the previous ARS devices is no longer supported
by the ARS 2000 SE series.
3.4.4 I/O functions and device control
Ten digital inputs provide the elementary control functions (see
chapter 4.6.5 I/O interface [X1],
page 48
):
The ARS 2000 SE series servo drives comprise a target table, in which the positioning targets are
stored and from which they can later be retrieved. At least four digital inputs serve the purpose of
target selection; one input is used as a start input. For further information, please refer to the Software
Manual “Servo drives ARS 2000”.
The limit switches serve the safety limitation of the motion space. During a homing one of the two limit
switches may serve as a reference point for the positioning control.
Two inputs are used for the power stage enabling on the hardware side as well as for the servo drive
enabling on the software side.
High-speed sample inputs are available for different time-critical applications (for example homing,
special applications).
The ARS 2000 SE series servo drives have three analogue inputs for input levels in the range of
+10V
to
-10V
. One input is designed as a differential input (16 bit), to guarantee high interference
immunity. Two inputs (10 bit) are single-ended. The analogue signals are quantized and digitalized by
an analogue-digital converter at a resolution of 16 bit or 10 bit. The analogue signals provide the set
points (speed or torque) for the control.
In common applications the existing digital inputs are already used for basic functions. For the use of
further functions such as teach-in mode, separate “start homing” input or stop input, the analogue
inputs AIN 1, AIN 2 as well as the digital outputs DOUT 2 and DOUT 3, which are also usable as
digital inputs, can optionally also be used.
