4.9 EEV interface (stepper motor drive/PWM)
Use
The unipolar motor outputs (only for POL461.45/STD and POL468.65/STD) are
used for unipolar stepper motors in full or half step mode.
Connection example
The following illustration shows examples of the position and identification of the
unipolar motor output connection.
The interface supports 5 or 6 wires. The difference is whether the wires are
connected to 2 coms or 1 com.
Stepper motor technical data
Motor Unipolar stepper motor, full step or half step
Excitation mode 1-2 phase excitation or 2-2 phase excitation
Supply voltage DC 12 V (short circuit protected)
Phase current
Max. 260 mA per phase when both EEV1 and
EEV2 are operating at the same time
If max. 375 mA is required per phase then only
one EEV (EEV1 or EEV2) can be operated at the
same time
Supported valves
Below list shows examples of compatible EEVs to the C400 controller. The list is
not inclusive.
