Status:it is always enabled and triggers the stopping mode (norm
EN60204-1) depending on the selected operating mode:
• category 1 in automatic mode
• category 0 in programming mode *¹
Signal: input used for the safety stop
function; connect a pair of
not-energized contacts of a safety device coming from the line. It is
physically identical to the E-Stop input and can be used for
functional purposes to trigger the Robot emergency stop without
acting on the E-Stop, that is typically enabled for wider geographic
areas.

Electric features:
– self-restoring fuse 1 A
– current on the contacts between 20 and 50 mA per each input
– voltage 24 Vdc

Status: it is always enabled.
Signal: output for the (not-energized) contacts of the emergency
stop push button on the Teach Pendant.

The emergency push button on the Teach Pendant is not directly
connected to the Control Unit emergency stop circuit.
The integrator shall:
–properly interlock the push button contacts with the machine
(cell / plant) emergency stop circuit
– remember to include also the Teach Pendant E-Stop push button in the
procedure for the periodic inspection of the machine emergency
devices.
Inside contacts electric features:
– max current 1 A
– typ voltage 24 Vdc, max 50 V
Note: install quick-fit protection fuse 1 A on the 24 Vdc power supply input (to be
carried out by the integrator)
*¹ For safety reasons, in Programming mode only category 0 stops are enabled (in compliance with EN
60204-1).
