PMA323BE HIEE300308R1 control unit module

Pressure/force controller: – PIDT1-controller – I-component can be cut in and out via window – Differential pressure evaluation – Own scan rate Velocity controller: – PI-controller – I-component can be cut in and out via window Monitoring functions: – Dynamic following error monitoring – Traversing range limits (electronic limit switches) – Cable break monitoring for incremental and SSI encoders – Cable break monitoring for sensors with 4 to 20 mA output

Not all of the channels can be used simultaneously. The voltage inputs and the current inputs are provided with a common pin so that either the voltage input or the current input can be used at a time. The current can be looped through several current measuring devices. Otherwise, a jumper must be plugged from pin “Iin“ to pin “analog_GND“. 2) If the factory settings are not sufficient, the measuring equipment can be calibrated on site according to the system requirements.

Due to the characteristics of these high-resistance inputs, no internal protective circuits with diodes or capacitors can be used. For this reason, when connecting analog signals to inputs Uimp1 to Uimp4, all required protective measures, EMC protection, signal filtration, must be connected externally in the incoming circuit. 4) Outputs “Uout 1“ and “Iout 1“ as well as “Uout 2“ and “Iout 2“ are electrically coupled. Normalization can be set to voltage or current by means of software.

Engineering notes

– If electromagnetic interference has to be expected, take suitable measures for ensuring the function (depending on the application, e.g. shield, filtration)! – Use low-capacitance cables; whenever possible, establish cable connections without intermediate terminals. – Electromagnetic sources of interference (e.g. frequency converters) must not be installed in the direct vicinity of the control electronics. – Power cables must not be routed in the direct vicinity of the controller card. – Do not install cables of the control electronics in the direct vicinity of power cables. – Install sensor cables separately. – The distance to aerial lines, radio sources and radar equipment must be at least 1 meter. – Use highly flexible CU conductors (min 2.5 mm2) for connecting the system ground! The system ground is an essential, integral part of EMC protection of the controller card. It dissipates interference that is transported to the controller card via data and supply voltage cables. This function can only be ensured, if the system ground itself does not inject interference into the controller card. Rexroth recommends that also solenoid cables be shielded. – Electrical signals brought out via control electronics (e.g. signal “no error”) must not be used for switching safety-relevant machine functions (see also European standard “Safety requirements for fluid power systems and components - hydraulics“, EN 982.) – For further notes, see WIN-PED 5 online help

Notes on use

The VT-HNC100...2X is exclusively intended for being integrated into a machine or system or assembled with other components to form a machine or system. The product may only be commissioned when it is integrated in the machine/system, for which it is intended. Adhere to the operating conditions and performance limits specified in the technical data. The VT-HNC100...2X is used for the open and closed-loop control of position, pressure and velocity of electrohydraulic axes. For operation of the device an additional, higher-level control logic with corresponding I/O components is required, which, in conjunction with the VT-HNC100...2X, holistically control the motion sequence of the machine and also monitor it with regard to safety. The VT-HNC100...2X must not be used in explosive atmospheres. The VT-HNC100...2X is technical equipment that is not intended for private use.
