Functional Safety (Certification in Progress)

Introduction

The Gate Suppress function can be utilized to perform a safe stop according to the EN60204-1, stop category 0 (Uncontrolled stop by power removal). It is designed to meet the requirements of the ISO13849-1, PL=d only in a system in which EDM signal is monitored by an “external device monitor”.

Stop Category defined in EN60204-1

Category 0 : Uncontrolled stop by immediate (< 200 ms) shut-down of the power supply to the actuators

Category 1 : Controlled stop by interrupting the power supply to the actuator level if, for example, the hazardous movement has been brought to a standstill (time-delayed shut-down of the power supply).

Category 2 : Controlled stop. The power supply to the drive element is not interrupted. Additional measures to EN 1037 (protection from unexpected restart) are necessary.

How it works

Interrupting the current to GS1 or GS2, for example removing the link between either GS1 or GS2 and PLC or both GS1/GS2 and PLC disables the drive output, i.e. the power supply to the motor is cut by stopping the switching of the output transistors in a safe way. EDM output is activated when GS1 and GS2 are given to the drive.

Always use both inputs to disable the drive. If for any reason only one channel is opened, the drive output is stopped but the EDM output is not activated. In this case the Safe Disable input wiring must be checked.

Activation

Turning on the safety switch automatically assign the GS1 input and GS2 input automatically.

To assign EDM (external device monitor) output, please turn the EDM function switch on. EDM output is automatically assigned on intelligent output terminal 11.
