S MODE: Pump torque equals 90% of engine target torque T, IS is the constant current value.
*
L MODE: Pump torque equals 70% of engine target torque T, IL is the constant current value. (Same as F mode).
*
If engine RPM is less than 1200 rpm: the current is the same as L MODE irrespective of mode selection.
*
When L or F MODE are selected at the same time as travel (upper side pressure SW OFF, travel pressure SW ON) the current
*
is the same as S MODE providing engine speed is greater than 1200 rpm. (Purpose; travel smoothness.)
