Machine Operating Modes - General

Overview

The following machine operating modes are distinguished for the safety module eSM (see also EN 12417):

• Machine operating mode Automatic Mode for regular production

• Machine operating mode Setup Mode for setup work at the machine

Monitoring of Movements

The safety module eSM monitors the movements triggered by the drive. The safety module eSM does not modify reference values but intervenes if the active safety-related function detects that a limit value has been exceeded. If the movement cannot be stopped as required, the safety-related function STO (Safe Torque Off) is triggered.

Monitored movement with the safety-related function SLS while the guard is open is possible if the following conditions are met:

• Guard is open, the level at GUARD_A and GUARD_B is 0

• Machine operating mode Setup Mode is active, the level at the inputs SETUPMODE_A and SETUPMODE_B is 1.

• Enabling switch is activated (the level at the inputs SETUPENABLE_A and SETUPENABLE_B is 1)
