PB connector
The PB has an emergency stop button and an enable switch. The contact outputs of these can be used to connect to the
emergency stop circuit of the entire equipment via the SAFETY connector on the controller. This section describes
signal connections.
CAUTION
• Do not change or modify the cable and connector. Along with the input/output signals for the programming box, the PB connector
includes signals used to configure an external safety circuit, and so changing or modifying the cable and connector is very dangerous.
• Always configure an external safety circuit by using the SAFETY connector. Although the PB has an emergency stop button and an
enable switch, they do not function independently because the controller is designed on the assumption that an external safety circuit
is configured.
