Uses and wiring methods of FDA-5005□-5075□ are as follows.
1) The R, S and T terminals are used to connect main power supply of 3-phase AC 200-230[V] to
the power circuits.
*
(Note) Single-phase AC 220V may also be used; however, output may be lower than the rated
value.
Install overcurrent breaker on the main power supply input unit. Also, install noise filter on the
power supply input terminal to shut off noise coming from the power lines.
2) The R and T terminals are for the auxiliary power supply of the power circuit. Connect single-
phase AC 200-230 [V] to these terminals.
3) Connect regenerated resistance between P and B terminals.
The standard regenerated resistance (See Table 3.1) is a standard item. (Install it on the
electric panel.)
4) Connect the U, V and W phases of the servo motor to the U, V and W terminals.
5) Ground the terminal. Also connect the servo motor earth cable to this terminal.
