1. Safety instructions
Always pay attention to safety of people while operating a robot arm or
commissioning a robot cell! Make sure that nobody is within the operating range of
the arm or other danger spots!
CE marking: Robot arm and control system are just a part of one facility, which is
assessed in its entirety for risks and must comply with currently applicable safety
regulations. The commissioning engineer of the facility is responsible for this.
The robot's control system has no protective devices. To ensure the essential
safety of people, suitable components, such as safety relays and door switches,
must be connected.
Always disconnect the power supply before inserting or removing connectors, such
as the display with joystick, emergency stop, digital I/Os or external relays.
No hot plugging!
Work on the robot's electronic system should only be carried out by qualified
personnel. Observe the common ESD guidelines.
Do not install or remove modules during operation, nor should you plug or unplug
any connections during operation. For this, always turn off the system and unplug
the mains connector.
The robot arm must be set up on a stable surface and bolted or otherwise secured.
Use and store the system only in a dry, clean environment.
Use the system only at room temperature (15° to 32°C).
The ventilation of the system must be able to operate without hindrance. There
must be at least 10cm of space next to the robot's fan to ensure sufficient airflow to
cool the motor modules.

3. Dimensions
3.1 Lateral view
Diagram 1: Side view of the DCi robot. The robot axes (motors) are basically counted from the
robot base. So axis 1 is the vertical axis in the robot base. An effector (e.g., gripper) can be
attached to axis 4/5 (4 or 5-axis version).
A 4-axis robot has a mounting plate instead of the last axis.

Caution! The connection is proprietary.
It is not suitable for a null modem cable
or the like.
4.2 Digital Inputs/Outputs
4.2.1
Digital I/Os and the back wall
From the Digital Input/Output (DIO) board, 4 digital outputs and 4 digital inputs are routed to
the outside. If further inputs and outputs are required, 3 more each can be achieved on the same
module in the housing of the robot. Plug-in connectors are included.
The outputs are not galvanically isolated in delivery condition; 24V and GND of the robot
control system are used. If galvanic isolation is required, this can be done as described in
section 10.1 "Galvanic isolation".
For testing, an LED with series resistor (e.g., 2K) can be connected between e.g. DOut1
(switched + 24V) and GND of the right 6-pin plug-in connector. This can be switched later in the
software.
