Emergency Stop Concept In Accordance With Stop Category 1 - Siemens SIDOOR ATD401W System Manual

3.4 Safety functions
The output of the "AND0" block can be directly assigned a drive order or can be assigned
the prioritized STOP door command via an additional negation block. This corresponds to
enabling for the actual drive order. The following example illustrates this:
● Open drive order is activated.
● 2-hand control device inactive → STOP (highest priority)
● 2-hand control device active → STOP is cleared → OPEN becomes active

Emergency stop concept in accordance with stop category 1

This concept describes the implementation of the emergency stop function according to stop
category 1 in compliance with EN ISO 13850:2008.
Safe motor shutdown
SIDOOR ATD4xxW controllers have an internal, cyclically tested and monitored second
shutdown route according to PLd. This ensures safe shutdown of the motor (emergency
stop).
Door commands
The door command with the highest priority is STOP → ramp stop.
The status following the ramp stop can be defined with the "special" door command
expansion bit: "source voltage brake activated" or "coasting down" (deenergized or no
current).
