evc/epc Controller
With SAE J1939 Interface
Global Settings
Enable Auto-Reverse (On/Off)

When in HP Management or Anti-Stall
mode, if the measured RPM is ≤ RPM Stop
or No Load RPM, coil A current ramps
down to 0, and then coil B current ramps up
to the Reverse Set- point.

The module will try to restart normal
operation after the reverse cycle completes.
Reverse Time (0 to 65 Sec) – It sets the time that coil B will remain in reverse during an Auto-Reverse cycle.
Reverse Retry Count (0 to 65535) –The number of times the Auto-Reverse cycle will try to restore normal RPM
before declaring a fault and disabling the unit.
Reverse set-point (0 to 100%) – The percentage of Imax output current for coil B during the reverse cycle.
Fixed set-point (0 to 100%)

The percentage of Imax output current for coil A when the measured RPM is above the RPM slow or Max Load
RPM in “anti-stall with fixed command” or “HP management with fixed command”.
Recover from loss of signal

When “ON”, the evc/epc automatically recovers and returns to normal operation after the pulse input and the
analog input(s) are back in range.

The evc/epc automatically recovers from a SAE J1939 message timeout error.

The evc/epc automatically recovers when the reference voltages or the supply voltages are outside the
acceptable limits and recover.

The evc/epc will not automatically recover from a coil open or short error.
Hard stop if disabled
 When “ON”, coil A or B outputs are immediately set to zero without ramps whenever the enable input is set to
“OFF”.
 When “OFF”, the coil A or B outputs ramp down to zero when the enable input is set to “OFF”.
