SE HP series - Ultra high speed injection molding machine

injection molding machine control systemFault (motor starting circuit, controller)）

Motor starting circuit

Fault phenomenon1 Occasionally appearing when powered on“E.OC2”Alarm, occasional occurrence of "E.Enc1”call the police

Reason for malfunction1 Motor malfunction, later confirmed to be caused by a mouse bite on the coding line and signal feedback deviation leading to motor malfunction

Solution Normal after disassembling and repairing the motor

Fault phenomenon2 The motor trips immediately after starting, and the panel displays servo control abnormality, while the frequency converter alarm displays“E.EF”

Reason for malfunction2 The cause of the malfunction is due to "abnormal servo control", and upon inspection of the circuit, it was found thatB34The 'servo controller' point has no input, this input point is damaged.

Solution After replacing the input point, the fault was resolved

Fault phenomenon3 Flow setting59The above motor is overloaded

Reason for malfunction3 After removing the contactor, it was found that two pairs of contacts were burnt out

Solution Troubleshooting after replacing the new contactor

Reason for malfunction4 B+Exposed copper wire, caused by touching the shell

Solution Which one may be observed for a few hours normally

Fault phenomenon5 The device will sound an alarm when the new machine is turned on

Reason for malfunction5 HPC09The output socket of the power board is not securely plugged in, resulting in voltage loss

Solution Twist off some parts with diagonal pliersPVCCable tray, reconnect, power on, normal

Fault phenomenon6 The motor cannot start

Reason for malfunction6 The computer board is not outputting

Solution Repair or replace the computer board

Fault phenomenon7 The motor cannot start

Reason for malfunction7 The communication contactor is broken

Solution Replace the AC contactor

Fault phenomenon8 The motor cannot start

Reason for malfunction8 Thermal protection relay or thermistor protection fault

Solution Replace the thermal protection relay and thermistor, normal

controller

Fault phenomenon1 Press the motor start button, the button light will turn on, but the motor cannot start

Reason for malfunction1 On the computer board220VThe fuse is burnt out

The solution is normal after replacement

Fault phenomenon2 As soon as the motor starts, there is pressure on the system pressure gauge

Reason for malfunction2 Proportional pressure and flow rate10VVoltage, circuit board malfunction

Solution Bring the circuit board back for repair

Fault phenomenon3 After program version change, semi-automatic loop1-5The module crashes due to unequal waiting time

Reason for malfunction3 Program issue, internal parameter usageSTAN4B1Caused by

Solution Enter the parameter screen and change the parameters again. Follow this method and there was no crash, indicating successful program transmission.

Fault phenomenon4 The screen displays' Please contact Haitian '

Reason for malfunction4 Panel（S7)Problem solution: The computer board needs to be repaired

Fault phenomenon5 Screen display in English (alarm, Fuji)09Computer)

Reason for malfunction5 Incorrect selection of a micro switch (analog) on the Fuji expansion board

Solution Adjust the position of the micro switch again

Fault phenomenon6 Alarm 'action timeout', switch to heating and motor

Reason for malfunction6 Computer internal parameter selection error

Solution Adjust the computer(HPC09)Internal parameters, no need to select 'energy-saving'

Fault phenomenon7 Reason for computer crash malfunction7 Circuit board damage

Solution Normal after replacing the circuit board

Fault phenomenon8 Manual light not on, LCD not displaying

Reason for malfunction8 Solution for broken computer board: The computer board needs to be repaired

Fault phenomenon9Manual light not on, LCD not displaying

Reason for malfunction9 Bipolar switch（380V）Jump away

Solution Normal after closing again

Fault phenomenon10 LCD white screen, no text

Reason for malfunction10 CPUBoard malfunction

Solution brought back for repair

Fault phenomenon11 After turning off the main power and restarting, the original parameters will change

Reason for malfunction11 The panel does not have a memory function

Solution: The computer board needs to be repaired

Fault phenomenon12 High proportional current, uncontrolled action

Reason for malfunction12 The locator for the proportional current of the computer board needs to be adjusted

Solution Adjust the locator, the action is normal

Fault phenomenon13 After booting up, the proportional current reaches its maximum value, and the server alarms

Reason for malfunction13 The computer board is broken and the proportional current output is at its maximum, causing the server to overload

Solution Repair computer board (can be repaired on-site)

Fault phenomenon14 The locator for adjusting the proportional current cannot adjust the current properly

Reason for malfunction14 The neutral wire is electrified

Solution Re ground and check the peripheral circuit

Fault phenomenon15 The actual positions of the switch mold, injection, and ejection actions remain unchanged0

Reason for malfunction15Motherboard（AK668）Bad

Solution: The computer board needs to be repaired

Fault phenomenon16 When fully automatic, there is a significant impact during the seat movement.

Reason for malfunction16 After high-pressure mold locking, the pressure did not release, but the inlet valve of the seat has been opened, causing

Solution Turn off the system parameter delay from the original0.05change to2The machine is running normally

Fault phenomenon17 Sometimes there is no action when pressing the button

Reason for malfunction17 Multiple buttons sometimes have poor contact

Solution: Replace some buttons

Fault phenomenon18 Traffic in15－25There is no movement between the machines

Reason for malfunction18 There is an issue with the linearity of traffic

Solution After readjusting the internal parameters of the computer, it returned to normal

Fault phenomenon19 During normal production, the computer will restart

Reason for malfunction19 There is an issue with the panel

Solution: The computer board needs to be repaired

Fault phenomenon20 All the movements of the machine have slowed down

Reason for malfunction20 Abnormal proportional current

Normal after adjusting the solution
