Guard Door with Guard Locking

Overview

You can connect a guard locking device for a guard door to the output INTERLOCK_OUT of the safety module eSM.

If the velocity is 0, the level at the output INTERLOCK_OUT is 1. Several safety modules eSM modules can be interconnected by chaining the signal of output INTERLOCK_OUT and the input INTERLOCK_IN of the next safety module eSM.

By connecting the output INTERLOCK_OUT of a safety module eSM to the input INTERLOCK_IN of the next safety module eSM, you can chain signals, for example, for a multi-axis system.

When all axes signal standstill, the level of the output INTERLOCK_OUT of the last safety module eSM in the chain is 1.

If the input INTERLOCK_IN of a safety module eSM is not used, use the parameter eSM_BaseSetting to disable the corresponding input INTERLOCK_IN. The signal chain starts with this safety module eSM.

The safety module eSM detects an error if the level at the disabled input is 1.

If you want to chain the interlock signals (INTERLOCK_OUT connected to INTERLOCK_IN of the next safety module eSM) and if you use less than five safety modules eSM, install a "Connector with wire jumper for INTERLOCK signal" (available as an accessory, refer to Accessories and Spare Parts) in those slots in which no safety module eSM is connected. For example, if you use three safety modules eSM connected to CN1, CN2, and CN3, install a "Connector with wire jumper for INTERLOCK signal" at CN4 and another one at CN5.

Refer to Multiple Safety Modules eSM in Multi-Axis System Via eSM Terminal Adapter for additional details.

If you chain several safety modules eSM, set the parameter eSM_BaseSetting of the first (that is, the one connected to CN1) safety module eSM (input INTERLOCK_IN not connected, output INTERLOCK_OUT connected) to the value INTERLOCK_IN. If the output INTERLOCK_OUT of a safety module eSM is not connected, do not set the parameter eSM_BaseSetting of this safety module eSM to the value INTERLOCK_IN.
