Introduction to Heidenhain Manual Programming Example Heidenhain manual programming is the process of directly inputting machining programs by operating the buttons and knobs on the control panel. Although this method is not as convenient as using computer programming, it can be used as a backup solution when there is no computer or when the computer malfunctions. Manual programming mainly includes the following steps: 1. Choose a motion mode (such as straight line, arc, etc.) 2. Enter the coordinates of the starting and ending points 3. Enter interpolation parameters (such as velocity, acceleration, etc.) 4. Confirm and execute the program Example 1: Implementing Simple Linear Interpolation Using Heidenhain Manual Programming Assuming we want to implement a simple line interpolation with starting coordinates of (10, 10) and ending coordinates of (50, 10). We can m...

1、 Debugging:With PG card: A1-02 (control mode selection)=1 or 3 (with PG card control)Change to 0 (no PG card, V/F control) (Change control mode parameters after unplugging PG card) The alarm that frequently occurs after changing the control mode: H1-06 (function selection and setting of terminal S8) is changed to F (blocking the function of this terminal). Change H3-05 (multi-functional analog input terminal A3 function selection and setting) to 1F (disable this terminal function). CPF06 (selection card connection failure). After changing the alarm parameters, power off and restart. If there is still an alarm, upload the parameters to restore the factory settings.

Common faults and solutions of solenoid valves How to deal with the malfunction of the solenoid valve The rated voltage of the solenoid valve coil is DC12V DC24V、AC24V（50/60Hz）、AC110V（50/60Hz） 、AC220V（50/60Hz） 、AC380V（50/60Hz）。 Generally, in electrical design, either AC220V (no need to install switch power supply, low cost, simple circuit and easy maintenance) or DC24V (commonly used safe voltage, switch power supply/solenoid valve coils are easy to repair and replace) is used. Common faults of solenoid valves include: 1. Coil short circuit or open circuit:Detection method: First, use a multimeter to measure its continuity. If the resistance value approaches zero or infinity, it indicates that the coil is short circuited or open circuited. If the resistance value is measured to be normal (about tens of ohms), it does not necessarily mean...

With the continuous development of society, automation technology has been widely applied in various fields. Especially in the field of industrial automation, the emergence of various automation equipment and systems has improved production efficiency and product quality, while reducing production costs, injecting new impetus into the development of enterprises. The importance of communication protocols and standards in industrial automation is self-evident. This article will explore communication issues in industrial automation from two aspects: communication protocols and standards. 1、 Communication ProtocolCommunication protocol refers to the communication rules agreed upon by various devices during communication, which determines how information is transmitted and processed between devices. In industrial automation, there are many types of communication protocols, such as M...

The differences in communication protocols are reflected in transmission methods, data formats, etc. Their purpose is to achieve effective communication between and with systems. Different communication protocols have different characteristics such as speed and stability, and their applications cover multiple fields such as industrial control and services. The TCP/IP protocol is commonly used for network connections and provides reliable byte stream services. The UDP protocol has fast transmission speed but no connection guarantee, making it suitable for scenarios that require high real-time performance. The Modbus protocol is widely used in the field of industrial automation, supporting communication between various electrical devices. The CAN bus protocol is used in fields such as automobiles due to its high anti-interference ability and multi master station capabili...
