7. Torque Lmt P3, %
Torque Lmt P3, % is the maximum actuator output current in percent at the third
torque limit.
8. Torque Lmt P4, rpm
Torque Lmt P4, rpm is the engine speed in RPM at the fourth torque limit.
9. Torque Lmt P4, %
Torque Lmt P4, % is the maximum actuator output current in percent at the fourth
torque limit.
10. Maximum Fuel Limit
Maximum Fuel Limit sets the maximum actuator output current. If 100% is set at this
set point, the maximum actuator output current is 180 mA. Set this set point to a value
a little above the actuator output value for full load.
