2.10. Emergency Stop Sense Input (TB201)
This input is to be activated by an external fail-safe emergency stop circuit. It is not
intended to be an emergency stop circuit in itself. It 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.
If the ESTOP bit is enabled in the FaultMask axis parameter, the ESTOP input must be
driven to prevent the ESTOP fault condition.
For typical ESTOP wiring, see the following drawing.
Figure 2-23.
ESTOP Sense Input (TB201)
Connecting the E-Stop input to a relay or other EMI/RFI
noise producing device/circuit, requires one or more noise
suppression devices, such as those in Table 2-6, or other
appropriate devices.
