Main circuit terminal]
1.Uses and wiring methods of FDA6001C
~6004C
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 over current 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) Connect regenerative resistor between P and B terminals. The standard regenerative resistor
(See Table 3.1) is a standard item. (Install it on the electric panel.)
3) Connect the U, V and W phases of the servo motor to the U, V and W terminals.
4) Ground the terminal. Also connect the servo motor earth cable to this terminal.
