Installation and Configuration
2.4. Emergency Stop Sense Input (TB201)
The ESTOP sense input (TB201) 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. The ESTOP sense input should be driven by the user's ESTOP
circuit to either force the drive to disable, or decelerate to a stop then disable. Refer to
interconnection details.
W A R N I N G : The user is responsible for accessing operator risk levels and designing the
external safety circuits appropriately.
W A R N I N G : Opening the motor leads at the Motor Output while the axis is enabled will
damage the drive. To protect the drive, the ESTOP circuit should open the AC motor power
input (Motor Supply). Refer to
TB201 is scaled for an input voltage of 5-24 volts. Using a higher input voltage requires adding an external
series resistor to limit the current to 10 mA.
If the ESTOP bit is enabled in the FaultMask parameter, the ESTOP input must be driven to prevent the
ESTOP fault condition.

Electrical Noise Suppression Devices
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.
