Internal thermal relay (contact capacity, AC 240V, 2A max, Normally ON

(b-contact), internal thermal fuse (unrecoverable)

* : Value in ( ) indicates the allowable braking ratio for 400V class.

Note 1:Thermal relay and fuse are built into the braking resistor.

Note 2: Internal thermal fuse prevents excessive heat generation which may occur

due to misoperation (unrecoverable).

Note 3: An appropriate safety circuit is configured so that the main power of the

robot driver is turned off if the thermal relay is tripped (an alarm occurs).
