Important: Terminal block TB4 is an optional connector that provides a
convenient connection to the thermal overload switches of the servo
amplifier. This terminal block is typically used to interface the thermal
overload switches with PAL or the system E-STOP string. The servo
amplifier will operate normally without any external connections to
terminal block TB4.
Figure 13A.4 shows and lists the 2AX-D 8520 digital servo amplifier
connectors and terminal blocks.
