Guideline for long M12 cables on Danfoss stepper motor valves
• Long cables will lead to degradation of performance
• You can overcome this degradation by changing the settings for the valve driver. This guideline is based on the
cable type being the same type as the standard Danfoss stepper motor cable

Tip for updating I028 parameter for 15m-30m cables:
1. Use koolProg online service option (EKE should be connected)
2. Select the desired valve first
3. Again chnage to user defined option, the valve default settings of previous selcted valve will be loaded
automatically
4. Change only the I028 parameter. According to the value in below table
Table 16: Parameter setting for long M12 cable 15 - 30 m
