Fault 1: Low-Voltage Circuit Breaker Trips After Oil Pump Starts.
: The circuit breaker trips immediately after starting the oil pump.
Phase loss in the power supply.
Severely clogged high-pressure filter, increasing motor current.
Low-voltage circuit breaker setting too low.Check Power Supply.
: Use a multimeter to confirm all phases are present. Correct wiring if phase loss is detected.Inspect Filter.
: Replace the high-pressure filter if clogged, ensuring proper oil flow.:
Adjust Breaker: Increase the circuit breaker setting to match the motor’s rated current, per manufacturer specifications.
: Monitor power supply stability and replace filters regularly.Fault 2: Failure to Locate Reference Point During Startup.
: The press brake cannot find the reference point, halting operation.Loose grating scale readhead connection, preventing alignment with the reference point.
MaltaReconnect Grating Scale.
: Press the red stop button, secure the grating scale readhead, and manually lower the slider to align with the lower mold. Return to the reference point in semi-automatic or automatic mode.
Correct Shutdown Procedure: Manually lower the slider to align molds before shutdown, then restart and return to the reference point.
: Use a multimeter to confirm all phases are present. Correct wiring if phase loss is detected.Fault 3: System Screen Shows No Display, Appears Grayish-White, with Blinking Programming Key Indicator.
: Replace the high-pressure filter if clogged, ensuring proper oil flow.:
: Overloaded program buffer memory due to uncleared programs.Initialize System.
: Disconnect the main power, press “+ +” and “- -” keys simultaneously, then power on to enter initialization mode.Clear Memory.
: Input “1” to select the project, enter password “817,” and confirm to clear the buffer.: Clear unused programs after each job to prevent memory overload.
Fault 4: Inaccurate Grating Scale Counting, Causing Bending Angle Errors
Correct Shutdown Procedure: Grating scale feedback signal drops pulses due to contamination or poor installation.
: Use a multimeter to confirm all phases are present. Correct wiring if phase loss is detected.: Disassemble and clean the grating scale, ensuring dust and vibration protection.
: Replace the high-pressure filter if clogged, ensuring proper oil flow.:
: Redesign any improper mounting to enhance stability.Repair or Replace.
: Return faulty grating scales to the manufacturer for repair or replacement.: Implement dust covers and vibration-dampening measures for grating scales.
Fault 5: “X” or “R” Axis Safety Distance Alarm After Programming: The system alarms and halts due to safety distance violations.
: Input “1” to select the project, enter password “817,” and confirm to clear the buffer.Reprogram Parameters.
: Adjust the mold or program settings to eliminate conflicts.
Correct Shutdown Procedure: Check “X” and “R” axis limit settings in the control system.
: Use a multimeter to confirm all phases are present. Correct wiring if phase loss is detected.Fault 6: “X” or “R” Axis Drive Motor Error Alarm.
: Replace the high-pressure filter if clogged, ensuring proper oil flow.:
16# Alarm: Motor overload due to excessive mechanical resistance.22# Alarm: Encoder feedback signal issues from poor connections or interference.
For 16# Alarm: Inspect “X” and “R” axis transmission for flexibility, addressing excessive resistance or mechanical limits.
For 22# Alarm: Check encoder connections for loose contacts, disconnection, or signal interference.
MaltaFault 7: Discrepancy Between “Y1” and “Y2” Axis Displayed and Actual Positions.
: The control system shows incorrect “Y1” and “Y2” axis positions.
: Inaccurate reference point calibration.
Reinitialize Reference Point
Correct Shutdown Procedure: Perform reference point calibration after major adjustments or power interruptions.
: Use a multimeter to confirm all phases are present. Correct wiring if phase loss is detected.:
: The displayed “X” or “R” axis positions do not match their actual positions.
: Axis positions were moved during power-off, while the system retained the pre-shutdown position.
Reinitialize Axes.
: Replace the high-pressure filter if clogged, ensuring proper oil flow.:
: Disconnect the main power, press “+ +” and “- -” keys simultaneously, then power on to enter initialization mode.Fault 9: “Y1” and “Y2” Axis Position Deviation Exceeds Allowable Synchronization Range.
: The slider cannot move due to excessive deviation between “Y1” and “Y2” axes.: Improper shutdown without aligning the slider with molds, causing deviation from tool drop.
Adjust Parameters: Increase the synchronization deviation range by Ascending 5mm in system parameters.
: Input “1” to select the project, enter password “817,” and confirm to clear the buffer.: Enter manual mode, lower the slider, and allow the system to auto-correct the position.
: Always align the slider with molds before shutdown to prevent deviation.
