10 Allowance should be made for othersystem losses and also for fair wearand tear during the life of the motor ,pump and other system EFFICIENCY5. CIRCUIT ANDAPPLICATION NOTESDISPLACEMENT SELECTIONTo select either displacement , apressure at least equal to 2/3 of themotor inlet/outlet pressure (whichever ishigher) is required. In most applicationsthe motor inlet pressure will be inlet/outlet pressures below 3,5 bar(50 psi) a minimum control pressure of3,5 bar (50 psi) is required. In the eventof loss of control pressure the motorwill shift to its highest rapid reversing applications it isrecommended to externally source thecontrol oil supply direct from the systempump (use displacement control type X or C - not CS , C1 or C2 -in model code position ).STARTING TORQUESThe starting torques shown on thegraph on page 4 are average and will vary with system parameters. For Motors with low displacementbelow 50 in3and starting under load it is recommended to selecthigh displacement for SPEED OPERATION(High displacement mode)Minimum operating speeds aredetermined by load conditions (loadinertia, drive elasticity, etc.)
