When the regenerative brake transistor is damaged, the following sequence is recommended to prevent overheat
and burnout of the brake resistor.
*1 Since the
00310 or more
inverter is not provided with the PX terminal, a jumper is not need to be removed.
*2 Refer to the table below for the type number of each capacity of thermal relay and the diagram below for the connection. (Always install a thermal
relay when using the
00310 or more
)
