Risk of injury through electric shock and damage to the device!

Bring the bus terminal system into a safe, de-energized state before beginning to mount, disassemble, or wire the bus terminals!

Connection 2:

Please note the additional information and instructions

Please follow the instructions below and refer to the information in the technical specifications!

    Connection 3:

    Note on connecting two-wire cables

    If you are using two-wire cables, we recommend using a shielded cable for the PWM signal.

    Notes on connecting and operating the digital inputs

    Connection 4:

    Sensors with open collector output circuits

    A sensor with an open collector output circuit corresponds to the “Input Type”: “Ground Switching (NPN)”.

    • In this context, the switching thresholds defined by the manufacturer must be observed to determine whether the input signal should be interpreted as “normally open” or “normally closed”.
    Connection 5:

    Digital input wiring

    • 3-wire digital sensors must be used.
    • To ensure that the digital input functions properly, the sensor supply and the ground connection must be connected separately.
    • 2-wire digital sensors are not supported.
    Connection 6:

    Maximum cable length to the sensor/encoder

    • Signal cables to the sensor/encoder over 3 m must be shielded.
      The shielding must be state-of-the-art and effective.
    • The permissible cable length for signal cables is < 30 m.

    Notice

    Fast digital inputs – interference from interfering devices

    Please note that the input wiring has very little filtering. It has been optimized for fast signal transmission from the input to the evaluation unit. In other words, rapid level changes/pulses in the µs range and/or high-frequency interference signals from devices (e.g. proportional valves, stepper motor or DC motor output stages) arrive at the evaluation unit almost unfiltered/unattenuated. These interferences can be incorrectly detected as a signal.

    • To suppress interference, an additional input filter can be parameterized.
    • Furthermore, EMC-compliant cabling and the use of separate power supply units for the terminal and the devices causing interference are recommended.
