Z-ME-KZ-PS/GI plastic injection controllers
perform velocity and force closed loop controls, according to real time commands (analog or fieldbus) generated by machine control unit (e.g. PLC).
The controller receives position / pressure
feedbacks and generates reference signal to
the proportional valve which regulates the
hydraulic flow to the injection actuator.
The position feedback signal is software
selectable: SSI, incremental encoder, potentiometer or analog (voltage or current).
Remote pressure transducers have to be
remotely installed close to the injection
actuator and connected to the controller (see
section 5 ).
The machine electronic control unit manages
the injection process through dedicated digital commands or fieldbus communication.
Serial and Profibus (only for /BP option) ports
are available on the front panel for controller
configuration and diagnostics.

Software Features:
• Internal generation of injection cycle
• Setting of axis’s dynamic response (PID) to
optimize the injection performances
• Monitoring of injection process
• Software selectable range of electronic
reference analog inputs: voltage or current
• Diagnostics of the injection status
• Intuitive graphic interface
• In field firmware update through standard
serial communication port
• Internal oscilloscope function
