PDD500A101 3BHE037649R0101 The operating characteristics and lubricant condition of the guideways are usually at their optimum when they are delivered in delivery condition or when linear roller bearing and guideway assemblies are used in the feed spindle. This can be seen by the vibration behaviour of the saddle plate when the system is in motion. In order to determine variations and deviations from the ideal nominal values, piezoelectric accelerometers are mounted on the steel saddle plates on the guideway brackets. The accelerometers are suitable for use in coolant and harsh contaminated environments. The permanently attached two-wire individually shielded cable is completely encased in polyurethane. The sensor has a sensitivity of 100mV/g, a resolution of 0.001g and a frequency range of 5,000 to 50,000Hz for measuring energy spikes.

PDD500A101 3BHE037649R0101 provides the rolling bearing parameters to the connected signal converter via cable, as well as monitoring preset limit values. The signals are then separated into different frequency ranges or the pulse peaks are evaluated for energy using spike energy (gSE). 4-20mA and 0-10V signals are transmitted via the analogue outputs to the PLC, Schaeffler box (controller) and lubrication unit. This closes the loop between monitoring and automatic lubrication. The module’s dedicated processor greatly expands the number and type of third-party devices and systems that can be supported by the Ovation controller, as well as the increasingly complex data they provide. The module offloads all communication protocol processing previously handled by the controller, and also provides faster access to data from these devices and more efficient integration of information into the Ovation system.
