How to replace a AC servo drive

Servo drives play a vital role in electrical engineering and its automation. When a servo drive fails or needs to be upgraded, replacing the servo drive correctly is a key step to ensure the normal operation of the equipment. This article will detail the steps to replace the servo drive and what you need to pay attention to during the process.

Step one:  Preparation work
Before replacing the servo drive, a series of preparations need to be carried out, including cutting off the power, understanding the electrical connections of the equipment, and confirming whether the models and parameters of the old and new drives match.

1. Power off: Before replacing the servo driver, be sure to disconnect the power supply of the device to ensure safe operation.

2. Understand the electrical connection: Consult the electrical drawings and instructions of the device to understand the electrical connection method of the servo drive and its connection relationship with other components.

3. Confirm that the model and parameters match: Check whether the models and parameters of the old and new servo drives are consistent to ensure that the new drive can properly replace the old drive.

Step two: Disassemble the old servo drive
Before disassembling the old servo drive, you need to proceed with caution and follow these steps:

1. Disconnect the power: Confirm again that the device is powered off and turn off the main power switch to ensure safety.

2. Remove the connecting cables: First remove the connecting cables between the servo drive and other devices, such as encoder connecting cables, control signal cables, etc.

3. Remove the old drive: Depending on how the device is installed, use the appropriate tools to remove the old servo drive from the device. Be careful to handle it with care to prevent damage to the equipment.

4. Clean the work area: After disassembling the old drive, you need to clean the work area in time to ensure a clean and tidy environment for the next operation.

Step three: Install the new servo driver
During the installation of a new servo drive, be careful to ensure correct connections and necessary debugging:

1. Install the driver: Install the new servo driver to the device according to the installation method of the device, and make sure it is firm and reliable.

2. Connect cables: According to the electrical connection drawing of the device, connect the cables of the new servo drive and other devices one by one, paying attention to correct wiring.
