[2] Want to execute movement operation or parameter edit for all axes when multiple axes are connected to the
single equipment.
z Explanation of functions
[1] Power/emergency-stop terminal block (TB2)
Provide a contact output for the emergency-stop switch on the teaching pendant (RCA-T/E).
EMG1 and EMG2 connect to the emergency-stop switch on the teaching pendant when the
PORT switch is ON, or are shorted when the PORT switch is OFF.
These terminals comprise an interlock with a safety circuit provided by the user.
