Injection molding machine Rexroth servo drive maintenance case
Customer: Fenggang, Dongguan, a plastic products factory
Name: EFFORT injection molding machine
Model: Rexroth HCS03
Fault causes: on the power of the F8022 alarm
Failure analysis: the customer is in the start of the F8022 alarm, according to the working principle of the servo pump. Servo pump is a servo motor driven by the servo motor to the voltage signal is converted to torque and speed, the control of the main requirements of the motor: sensitive, accurate, reliable operation, less power consumption, etc.. The drive circuit and the detection circuit are normal in the static measurement of the open shell according to the fault inquiry. Link computer software testing found that the encoder circuit fault caused by the power measurement encoder circuit each working voltage found IC7 work is not normal. After replacing the link computer test is normal. Connection servo pump motor operation fault lift.
