Project planning notes  
▶ The A10VSO axial piston variable pump is designed  
to be used in open circuit.  
▶ The project planning, installation and commissioning  
of the axial piston unit requires the involvement of  
qualified skilled personnel.  
▶ Before using the axial piston unit, please read the corre-  
sponding instruction manual completely and thoroughly.  
If necessary, this can be requested from Bosch Rexroth.  
▶ Before finalizing your design, please request a binding  
installation drawing.  
▶ Pressure controllers are not protection against overpres-  
sure. A pressure relief valve is to be provided for the  
hydraulic system.  
▶ Working ports:  
– The ports and fastening threads are designed for the  
specified maximum pressure. The machine or system  
manufacturer must ensure that the connecting ele-  
ments and lines correspond to the specified application  
conditions (pressure, flow, hydraulic fluid, temperature)  
with the necessary safety factors.  
▶ The specified data and notes contained herein must  
be observed.  
– The working ports and function ports are only  
intended to accommodate hydraulic lines.  
▶ Depending on the operating conditions of the axial  
piston unit (working pressure, fluid temperature),  
the characteristic curve may shift.  
Safety instructions  
▶ Preservation: Our axial piston units are supplied as  
standard with preservative protection for a maximum of  
12 months. If longer preservative protection is required  
(maximum 24 months), please specify this in plain text  
when placing your order. The preservation periods  
apply under optimal storage conditions, details of  
which can be found in the data sheet 90312 or in the  
instruction manual.  
▶ Not all versions of the product are approved for use  
in a safety function according to ISO 13849. Please  
consult the responsible contact person at Bosch  
Rexroth if you require reliability parameters (e.g. MTTFd)  
for functional safety.  
▶ During and shortly after operation, there is a risk of  
getting burnt on the axial piston unit and especially on  
the solenoids. Take the appropriate safety measures  
(e.g. by wearing protective clothing).  
▶ Moving parts in control equipment (e.g. valve spools)  
can, under certain circumstances, get stuck in position  
as a result of contamination (e.g. impure hydraulic fluid,  
abrasion, or residual dirt from components). As a result,  
the hydraulic fluid flow and the build-up of torque in the  
axial piston unit can no longer respond correctly to the  
operator's specifications. Even the use of various filter  
elements (external or internal flow filtration) will not  
rule out a fault but merely reduce the risk. The machine/  
system manufacturer must test whether remedial mea-  
sures are needed on the machine for the application  
concerned in order to bring the driven consumer into  
a safe position (e.g. safe stop) and ensure any measures  
are properly implemented.  
▶ Depending on the type of control used, electromagnetic  
effects can be produced when using solenoids. When a  
direct current is applied, solenoids do not cause electro-  
magnetic interference nor is their operation impaired by  
electromagnetic interference.  
Other behavior can result when a modulated direct  
current (e.g. PWM signal) is applied. Potential electro-  
magnetic interference for persons (e.g. persons with  
a pacemaker) and other components must be tested  
by the machine manufacturer.
