Technical Specifications
For definitions of the following specifications, see
parameters.
Minimum for internal charge supply
at minimum charge pressure. Perfor-
mance (pressure and displacement)
may be limited due to limited control
pressure
Minimum for external charge supply
at minimum charge pressure. Full
performance (pressure and displace-
ment) possible at minimum charge
and control pressure supply.
