Stepper Motor Output

• The stepper motor is connected to the "Stepper Valve" terminals (see connection overview) with a standard M12

connection cable or JST XHP-5 connector.

• The default valve setting in EKF 1A/2A is: No Valve.

• The correct valve must be defined as per section DIP Switch – Valve

Valve Cable Connection

Danfoss recommends to use ETS 5M and ETS 6 valves to be connected to JST XHP-5 pin connectors instead of 4 pole terminal

block, but it is possible to connect to terminal block, follow color codes of wires of coil as shown in table below.

While using JST 5pin, its plug and play for ETS 6 and ETS 5M valves.

Guideline for long M12 cables for Danfoss stepper motor valves

• Long cables will lead to degradation of performance.

• Cable length for stepper motor connection must be less than 30 m.

• Danfoss recommends to use 4-20 mA signal for long distances and use shorter cable between driver and valve.
