To achieve Z-axis control, the method is as follows:

1 Ladder diagram compilation

 

 

 

 

Use the intermediate relay controlled by Y20.0 to control the brake 24V.

2 Parameter setting

2005.6 BRKC is set to 1

 

 

Set 2210 parameters as follows:

 

 

 

Word of experience: If it is an old machine tool that has been used normally for many years, the brake of the motor brake is generally worn, and the brake of the servo motor needs to be repaired. In a static state, the load of the Z-axis should not exceed 60%. If the motor is overheated with a large load for a long time, it will cause wear-resistant flat wear in the brake, which will lead to a fall without tightening.
