M2000 - Control Products Sheet 1.2 M2000 Programmable Pressure/Position (P/X) Controller E122-215-002 Single Eurocard Single Axis, RS-485 PC Tuneable Features: Ü PID Pressure (P) Control Ü Speed Ramped Position (X) Control Ü Smooth Transition from (P) to (X) Ü PLC Interface Analog and Logic I/O Ü Auto Calibration of (P) and (X) Datum's Ü Built in Commissioning Interface Description I I/O Cond.n I E122-215 P/X Controller P I Out P P X In Machine Interface Application The E122-215-002 (P/X) controller is designed for Ü Presses hydraulic control systems where both position and Ü Roll Nip Control the operating cycle). Typically the system might Ü Material Test operate in position control mode but be armed to Ü Injection Moulding switch over to pressure control mode at the Ü Reel winding pressure needs to be controlled (at different parts of appropriate moment. Where necessary the switch over can be achieved in such a way as to minimise the transition (often referred to as bumpless transfer). In either mode of operation an analog command interface allows adjustment of the system set points Note: from an external host controller (e.g a PLC). The The exact specification of the various operating same system may also be used to set the various modes is beyond the scope of this document. Consult operating modes and respond to controller status via Moog Controls Limited for more details. See overleaf the logic I/O interface. for functional block diagram.
