Sprint Electric offers a Programmable Logic Arithmetic unit (PLA) with extended functionalities for diverse applications and motion tasks. The PLA is a stand-alone applications module that can compliment and enhance any analogue or digital drives system, simplify system design and reduce or eliminate the need for PLC or PC based systems.
Designed primarily for use by system integrators, the PLA offers a powerful and flexible method of processing analogue and digital signals via easy to use configurable software blocks. The PLA enables the user to define a control strategy to exactly meet the demands of the process or application. The block diagram created is flexible and has a unique 'Configuration Checker' detecting shorts within the user-defined connections. The standard application blocks in the PLA include diameter calculator, taper tension calculator, torque compensation for inertia and friction, motorised pot simulator with power loss memory, two high performance PIDs with gain profiling, two summers with inverting scaling clamping and hysteresis, two filters with precision time constants from milliseconds to 30 seconds, delay timer with roll-over facility, linear or 'S' ramp, and many more.
All the facilities can be programmed and interconnected with each other and/or the extensive input/output facilities in the PLA. All source and target parameters are described in English or selectable other languages. Additional input/output facilities can be programmed and monitored in engineering units.
