Fine speed type SMD2-FCAUTIONUse with oil-free specifications.Lubrication may change characteristics.Assemble the flow control valve near the cylinder.Adjustments become unstable if assembled away from the cylinder.Use the SC-M3/M5, SC3W, SCD-M3/M5, SC3WU Seriesspeed control valve.Generally, the higher air pressure, and the smallerload pressure result in the more stable operation.Keep the load factor at 50% or less.Stable speed control is achieved with a meter-outcircuit.When driving the single rod cylinder at fine speed with theoperation direction set to PUSH, popping-out may occur if operationis started when load resistance is small. As a countermeasure,use (b), (c), or (d) circuit.Note that the (d) circuit isthe most stable.acPUSH: meter-outPULL: meter-outPUSH: meter-inPULL: meter-outbdPUSH: meter-inPULL: meter-inPUSH: meter-in/outPULL: meter-outDesign & Selection(Note 2) When installed vertically, the load will drop naturally if themeter-in circuit is used. Use the meter-out circuit in this case.Speed controlis unstableDrops naturallywhen lowering(Note 3) Connect the peed control valve in the parallel with the followingcircuit.(Cause of popping out)Reduce the flow rate to reach a fine speed at the exhaustside in a mater-out circuit. This results in the samepressure level on the both sides immediately after valveswitched. The thrust caused by the differential of pressurizedarea of piston is applied to the PUSH direction and apopping-out of piston rod occurs.(Guide for popping out occurrence)Popping out occurs when: the piston rod area x airpressure> load resistance.Do not apply lateral load a cylinder.Install the cylinder to avoid the sliding guide to betwisted.The presence of load or resistance variation may result in unstableoperations.Operation of a guide having a large difference in stationaryand moving friction may become unstable.d Speed adjustment method of PUSH operation of circuit:1. Set the speed with the x speed control valve2. Lower the flow rate with the y speed control valve until popping out no longer occurs3. Reconfirm speedAvoid use with vibration.The product would be adversely affected by vibration and operationmay become unstable.(Note 1) When b, c and d are compared, d circuit operation is most stable.1004
