NUM C057 NUM 1040 Industrial CNC Controller
Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The NUM C057, identified as the NUM 1040, is an industrial CNC controller from the NUM 1000 product family. It combines numerical control with PLC-based machine management for controlling machine functions and coordinating auxiliary equipment in legacy CNC installations. The controller uses a 32-bit Motorola 68020 processing architecture and is relevant to existing NUM 1000-series machine-tool control systems.
The base machine interface provides 32 digital inputs and 24 digital outputs through the 32-24 I/O card arrangement, with expansion to 64 inputs and 48 outputs through a compatible 64-48 I/O card. A machine panel extension can add up to 32 inputs and 24 outputs, while the analog I/O connection provides one analog output. For a replacement, match the installed I/O card, machine panel extension layout, serial interface configuration and overall NUM 1000-series system architecture before commissioning the spare.
The NUM C057 NUM 1040 is a discontinued legacy CNC controller intended for repair, replacement and refurbishment work on existing equipment. Practical replacement checks include confirming the C057 part number, NUM 1040 model, installed I/O arrangement and connections to external peripherals. When an exact or architecture-matched unit is required, repair or a tested exchange controller can help preserve the original CNC and PLC control structure.

Communication and System Integration
The NUM C057 provides built-in serial communication for peripherals used in legacy CNC installations. COM 1 uses RS-232E, while the secondary serial line can be configured for RS-232E, RS-422A or RS-485 operation.
When replacing the controller, the serial interface standard must match the connected peripheral and the existing machine wiring. The communication arrangement should be checked together with the NUM 1000-series system configuration and the installed I/O architecture.
Replacement and Spare Part Considerations
The NUM C057 NUM 1040 is used for replacement and repair of existing NUM 1000-series CNC control systems. Before selecting a spare, confirm the exact C057 part number and NUM 1040 model together with the installed 32-24 or 64-48 I/O card configuration and any machine panel extension.
The replacement must also match the machine's serial communication arrangement: COM 1 uses RS-232E, and the secondary serial line may use RS-232E, RS-422A or RS-485. Checking the peripheral connections and system architecture before commissioning helps avoid an I/O or communication mismatch.
