Application Example - Danfoss VLT Integrated Servo Drive ISD 510 System Operating Instructions Manual

ISD Safety Concept

8.10 Application Example

Illustration 8.2 shows an example of an installation for 2 lines that can be put in Safe Torque Off mode by separate safety
circuits for each line.
The safety circuits may be remote from each other and are not supplied from the ISD 510 servo system.
The 2 lines in the example are controlled separately. If the Safe Torque Off function is triggered on line 1, line 2 remains in
normal operation and the servo drives on this line are not affected. There may still be a hazard from the servo drives on
line 2.
Select the safety switch devices in accordance with the requirements of the application.
