2.4.2 Wiring of emergency stop input (TB3)
Rated voltage 24V ±10%, rated current within 5mA
The emergency stop input will be effective as default setting.
Refer to the “AX Series TS, TH Type manual” for setting instructions.
Emergency stop is a “b” contact input. Thus it will take effect when emergency stop input
(TB3) becomes open. (Emergency stop using PROFIBUS will be effective when the input
data is OFF
）
Emergency stop can be inputted by TB3’s input terminal or CN3’s PROFIBUS
communications and if one of the inputs becomes open (or off), it will be recognized as
emergency stop.
→
Input to TB3 is necessary to release the emergency stop.
The cable sheath peeling length should be 8 or 9mm.
The applicable cable is AWG20 to 24 (single cable) or AWG20 to 22 (stranded cable).
