evc/epc Controller
With SAE J1939 Interface
Closed Loop Speed Control
The
“evc Closed Loop” Graphical User Interface must be selected.
Set the coil min, max current and the PWM frequency according to the valve specification.
The reference and the feedback can be set by
either of the command voltage, pulse voltage,
pulse rpm, J1939, etc.
In this example, the reference A is set by the
command voltage.
The feedback is set by the pulse rpm.
The maximum displayed RPM is for the display
only.
In this example, the analog input demands 95% of the maximum displayed rpm which is 1900rpm. The measured
rpm is 1892rpm. The evc/epc controller will increase the current to maintain 1900rpm until the current reaches the
max setting.
