Technical Specifications Power Supply: 24V DC auxiliary power Operating Temperature: 0℃ ~ 55℃ Mounting: Rack slot mounting inside servo controller cabinet Signal Interface: Encoder feedback, digital I/O, bus communication Humidity: 5% ~ 95%, non-condensing
Functional Features Execute multi-step bolt tightening program algorithm. Receive torque and angle feedback signal from transducer. Output servo drive command for speed and torque control. Tightening curve data acquisition and storage. Over-torque, under-torque and angle fault detection. Industrial bus communication with upper host PLC.
Application Scenarios Automotive assembly servo bolt tightening workstation. Heavy machinery precision screw fastening production line. Rexroth servo nutrunner control cabinet spare parts. Automated assembly industrial production equipment. High precision torque control system maintenance.
Performance Parameters Control response: Fast closed-loop control cycle Sampling rate: High frequency torque and angle signal acquisition Fault reaction: Quick protection trigger for abnormal tightening Communication: Stable real-time data exchange with upper controller
Material Composition PCB Substrate: Flame retardant high reliability fiberglass board Electronic Components: Industrial grade DSP, memory and passive components Connector: Gold plated terminal connectors for signal and power
Structural Characteristics Standard plug-in PCB assembly. Surface mount high-speed processing chips. Multiple pin headers for feedback, I/O and bus wiring. Metal fixing lugs for cabinet installation. Low noise PCB layout for high precision signal collection.
Working Principle The control board loads predefined tightening program, receives torque and angle feedback signal from transducer, calculates deviation between actual value and target value, outputs control command to servo power unit, and judges pass/fail result after tightening cycle finished.
Installation Requirements Cut off cabinet main power and 24V auxiliary power before replacement. Insert PCB into controller guide slot and fasten fixing lugs. Check all signal and power connectors are fully seated. Restore cabinet wiring and inspect short circuit risk. Power on, download tightening program and run functional test.
