DELEM DA-51 CNC Press Brake Controller

Technical Specifications

Model: DA-51 Brand: DELEM (Netherlands) Product Type: CNC Press Brake Controller Mounting: Panel mounting on bending machine cabinet Operating temperature: 0℃ ~ +45℃ Storage temperature: -20℃ ~ +70℃ Relative humidity: 5%~95%, non-condensing Protection: IP20 (front panel) Power supply: 24V DC Weight: 4.2 kg

System compatibility

DA-51 is a multi-axis CNC controller for DELEM hydraulic press brake systems. It cooperates with DELEM DM series axis control modules, linear encoders and hydraulic proportional valve units, widely used in metal fabrication workshops for controller replacement during bending machine overhaul.

Function

DA-51 serves as the core operation control unit of hydraulic press brake. It supports angle programming, stores up to 500 product programs with maximum 25 bends per program. It realizes Y1,Y2,X standard axis control, optional R/Z/X2 auxiliary axis, supports crowning compensation function. It monitors ram position, tonnage and machine running status, and triggers alarm signals once over-travel or hydraulic faults are detected. It is used to replace damaged controllers when the press brake cannot complete multi-axis bending programming.

Installation

Cut off main power supply before installation. Reserve panel cutout on machine cabinet, mount DA-51 and lock fixing fasteners. Connect 24V DC power, fieldbus, encoder cables and hydraulic valve signal terminals. Check wiring definition, upload machine parameters, perform trial bending test before formal production.

Interface

Encoder input ports, digital I/O terminals, RS232 communication port, status LED indicators for DELEM DA-51 controller.

Feature

Original DELEM controller, monochrome LCD display, physical keyboard operation, one-page programming layout, built-in tool and material library, bend teach-in function, compatible with servo, inverter and AC drive systems. This legacy spare part supports field repair of old DELEM hydraulic press brake systems.

Diagnostic

No display after power on: check 24V DC power supply and power fuse for DA-51. Axis positioning deviation: verify encoder wiring polarity and machine parameter setting. Intermittent communication alarm: inspect bus cable shielding and cabinet grounding condition.

Product Brief

DA-51 is Dutch DELEM CNC controller for hydraulic press brake. It executes angle programming and up to 4+1 axes closed-loop control for sheet metal bending operation, classic spare part for legacy metal fabrication machine overhaul.
