Z-ME-KZ digital axis controllers perform the
position closed loop of linear or rotative
hydraulic axes.
The controller receives a position feedback
from the axis transducer and it generates a
reference signal to the proportional valve
which regulates the hydraulic flow to the
actuator.
The position feedback interfaces are SSI,
incremental encoder, potentiometer or stan-
dard analog inputs (voltage or current)
software selectable.
A front panel serial port is always present for
configuration and monitoring of the controller.
The controller can be operated in real time
by external or internally generated reference
signal.
With external reference signal the actuator’s
motion cycle can be managed by either ana-
log or fieldbus reference input.
With internally generated reference signal the
actuator’s motion cycle can be managed by
external or fieldbus on/off commands.
A pressure/force alternated control may be
set by software additionally to the position
control: a pressure/force transducer has to
be assembled into the actuator and connec-
ted to the controller; a second reference
pressure/force signal is required.
Several auxiliary digital inputs/outputs are
available and they can be used to synchroni-
ze other machine functions and to transmit
information on the controller state.
Electrical Features:
• 4 digits front panel display to check and
change parameters as well as for diagno-
stics
