Power supply voltage of the
SINAMICS HLA
Operating a TTL or SSI
encoder.
TTL and SSI encoders
cannot be operated at the
same time on one slot.
Two pressure sensors are
provided for each axis to
determine the cylinder
pressure at the A and B
sides.
The sensors are used to
sense the pressure at the
shutoff valve.
This is the only interface to
the servo solenoid valve
and transfers the power
supply voltage, setpoint,
and actual value.
Power supply for the
hydraulic components
One shutoff valve is
connected for each axis
For especially safety-critical
applications, shutoff valves
can be used whose actuator
position is monitored using
sensors.
The power enable signal for
the SINAMICS HLA is
switched using the EP
terminals. Each channel of
the SINAMICS HLA is
equipped with its own EP
terminal.
