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
, after coil A ramps down
to 0, coil B will ramp 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 the demand for coil B during the reverse cycle.
Fixed set-point
(0 to 100%)

The demand 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 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
limits and recovered.

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 switch
is “
OFF
”.

When “
OFF
”, the coil A or B outputs ramp down to zero.
