Processing Capabilities and Axis Control
The processor module executes part program blocks with high-speed look-ahead interpolation. It manages four axes simultaneously for complex 3D contouring operations. The ABB 07 ZE 85 provides linear, circular, helical, and spline interpolation functions. The module includes advanced look-ahead for smooth acceleration at high feed rates. It also performs tool radius compensation and cutter length offset calculations automatically. A green LED indicates proper processor operation and program execution. The module supports both absolute and incremental programming modes.
PLC Functions and Machine Interface
The processor module integrates programmable logic control for machine auxiliary functions. It handles spindle control, coolant activation, and automatic tool changer sequencing. The ABB 07 ZE 85 supports up to 256 digital inputs and 192 digital outputs. The PLC logic executes independently from the part program processing. You can program the PLC using ladder logic or instruction list languages. A yellow LED flashes when the PLC detects any machine fault condition. The module stores PLC program in battery-backed RAM permanently.
Installation and Operational Guidelines
You must insert this module into a dedicated slot in the Procontic rack. The backplane supplies 5V and 24V DC power to the module automatically. The ABB 07 ZE 85 draws approximately 600 mA from the 5V supply rail. The lithium battery retains RAM data for up to three years without power. You should replace the battery every five years for reliable operation. The module stores no program in RAM when you remove the battery. Therefore, keep the application backup on your programming computer. The operating temperature ranges from 0°C to 50°C.
