Installation and Configuration

2.8.1. Emergency Stop Sense Input (TB103)

The ESTOP sense input is used to monitor the state of an external safety circuit only. This state is indicated
by the software and may be used to facilitate system restart. This ESTOP sense input is not intended to be a
complete safety system.
W A R N I N G : The user is responsible for assessing operator risk levels and designing the
external safety circuits appropriately.
The ESTOP input is scaled for an input voltage of 5-24 volts.
If the ESTOP bit is enabled in the FaultMask axis parameter, the ESTOP input must be driven to prevent the
ESTOP fault condition.

N O T E : Connecting the ESTOP input to a relay or other noise producing device requires the use of noise
suppression devices such as those in
suppress transient voltages.
