Fully electric dual material injection molding machine

injection molding machine control systemFault (electrical main circuit, frequency converter)）

Main electrical circuit

Fault phenomenon1 The motor can start without any action, and the number of the frequency converter remains unchanged

cause of failure1 No feedback signal from pressure sensor

Solution Pressure sensors andJ5The wiring between the boards is loose, but after tightening, it is normal

Fault phenomenon2 During the production process, the main switch often trips

cause of failure2 MAThe machine configuration leakage switch must be equipped with a dedicated switch

Solution Temporarilyru38(Carrier frequency),Originally for4change to2）After observation, there was no further tripping. The final configuration requires a current greater than300MAThe leakage switch.

Fault phenomenon3 The motor can start, the ammeter shows current, but the machine does not move

cause of failure3 Enable no

Solution The relay has poor contact, but after replacing the contacts, it returned to normal

Fault phenomenon4 The position ruler data fluctuates greatly

cause of failure4 Communication connection issue

Solution Turn off the power, unplug the communication cable, and then power on again. The position gauge data is normal and all actions are normal

Fault phenomenon5 The machine has no movement

cause of failure5 Flow proportional valve ammeter current none

Solution The plug of the flow valve coil is loose, but it works normally after being plugged in

Fault phenomenon6 Manual light not on, LCD not displaying

cause of failure6 Peripheral phase loss, fuse broken

Solution Normal after replacing the fuse

Fault phenomenon7 The machine cannot operate, and there is an abnormal alarm in the safety circuit

cause of failure7 The safety relay is broken

Solution Need to replace the safety relay

Fault phenomenon8 All temperatures are displayed988

cause of failure8 Peripheral phase loss, faulty air switch

Solution Normal after replacing the air switch

Inverter (Huichuan)

Fault phenomenon1 When the pressure is relatively high, the pressure gauge will shake

cause of failure1 Unreasonable internal parameter settings of the frequency converter

Solution Normal after modifying the internal parameters of the frequency converter

Fault phenomenon2 Display "servo controller abnormal" alarm

cause of failure2 The zero position of the frequency converter is incorrect

Solution The frequency converter returns to normal after resetting to the zero position

Fault phenomenon3 All movements are relatively slow

cause of failure3 Remove the frequency converter and replace it with a power frequency connection

Solution for normal production

Fault phenomenon4 After a period of production, the frequency converter will appearOH2call the police

cause of failure4 The solution is that the peripheral waterway has not been properly connected Normal after adjusting the waterway

Fault phenomenon5 Inverter overheating alarm,E.OHcall the police

cause of failure5 The waterway is blocked and the cooling water is not turned on

Solution Normal operation after opening the cooling water

Fault phenomenon6 Inverter overtemperature alarm

cause of failure6 The frequency converter is broken

Solution Repair or replace the frequency converter

warranty

New products are guaranteed for one year;For all products and projects that we repair or sell (old parts), we offer a three-month full warranty (i.e. we provide warranty for any type of malfunction during the warranty period). In case of special circumstances, we will communicate with you clearly before the repair. Let you understand and consume with peace of mind.

support

When both of us have already understood each other and you have a certain amount of transactions every month, during the maintenance period of your repair products, as long as we have the same model of finished products in stock, we can lend them to you for free until your repair products are repaired; Whether you have worked with us or not, if you have any technical issues, you can consult us for free by phone, and we will do our best to assist you in solving the problem.
