Stepper Motor Output
• All Valves are driven in a bipolar mode with a 24V supply that is chopped to control the current (Current driver).
• The stepper motor is connected to terminals 5 to 8 (see terminal assignment) with M12 motor cable.
• To configure stepper motor valves other than Danfoss stepper motor valve, it is necessary to set the right
valve parameters as described on section Valve configuration. The default valve setting in EKD 316C is
16 (i.e. 'non')
• It is neccesary to define correct valve in 'Valve type' i,e parameter n03. The overview of the valve types has
been defined in section "valve overview".
