If you have difficulties in commissioning your D1, we stated the most frequently asked questions here.
Please always use the latest firmware of the D1. It is available at
How do I determine the rotation direction of the motor?
How do I connect a limit switch?
How do I determine the position of a limit switch?
Is there anything special to consider when commissioning a brake?
Is the igus motor encoder an incremental or absolute encoder?
Is there a sample program demonstrating the communication of the D1 with a Siemens PLC?
Is there a sample program demonstrating the communication of the D1 via Modbus TCP/IP as a gateway?
During commissioning or during operation, an error message is displayed. What is wrong?
Is your request not addressed in this list? Please send us a support request with your current configuration file of the D1 to
How do I determine the rotation direction of the motor?
(p. 47). The determination of the rotation direction is illustrated in a picture.
How do I connect a limit switch?
The following applies to the igus limit switches: The brown wire is connected to 24V and the blue wire to 0V. Depending on the
position, the black wire is connected to terminal X2.8 or X2.9 of the dryve D1. The supply voltage (brown and blue wire of the
limit switch) is not provided by the D1. The cores must be connected to external terminals (e.g. in your switch cabinet).
How do I determine the position of the limit switches?
(p. 47). There you will find a graphic illustration of the position determination.
How do I connect a motor?
(p.21). The motor connection is illustrated in a picture.
Is there anything special to consider when commissioning a brake?
During initial commissioning or after a longer standstill period of the brake, a grinding process must be performed. To execute it,
please refer to the relevant motor data sheet and follow the instructions in the sub-section "Holding brake".
Is the igus motor encoder an incremental or absolute encoder?
igus motor encoder are incremental encoder. Please refer to the corresponding data sheet.
Is there a sample program demonstrating the communication of the D1 with a Siemens PLC?
Sample programs demonstrating the communication of the D1 with a Siemens PLC are available in different versions.
