Operating Guide

8.6.1 Protective Measures

• Install the system modules in an IP54 cabinet as per IEC 60529 or in an equivalent environment. A higher IP protection may be
necessary for certain applications.
• If external influences can affect the motor axis, for example suspended loads, use additional measures, such as a safety holding
brake, to eliminate hazards.

8.7 Application Example

An example of an application that can be put in Safe Torque Off mode by a safety circuit is shown in
Select the safety switch devices in accordance with the requirements of the application.

8.8 Commissioning Test

-
Perform a commissioning test for the whole servo system after installation of the STO function, after every change to the
installed function, or after a safety fault.
There are 2 ways to implement the commissioning test depending on the method used to program the PLC, however the steps of
the test are the same:
• Using the Danfoss Library.
• Bit-wise readout of the status.

8.8.1 Commissioning Test using Libraries

Depending on the application, 1 or both of the following libraries are required to program the commissioning test:
• Danfoss Library
- MC_ReadAxisInfo_DDS
- MC_ReadStatus_DDS
- MC_ReadAxisError_DDS
- MC_Reset_DDS
