Mitsubishi inverter OC (overcurrent problem) will be caused by the following reasons, taking A500 series inverter as an example: 1). Caused by improper parameter setting problems, such as time setting is too short. 2）. ...

In GX Works3, there are three types of security settings: block password, security key, and file password. The block password is for the program to prevent others from reading and writing changes, only for the program; The file password is for the PLC to prevent others from reading and writing changes. Security keys are both capable of ...

The new iQ-F motion module is a controller that can perform advanced motion control such as positioning, synchronization, cam, speed, torque, etc., with a computing cycle of 500μs, and can be connected to a high-function servo amplifier through CC-Link IE TSN, making a higher contribution to the miniaturization and high functionality of the equipment. ...
