wiring
Three-phase 200V class
FR-E720EX-0.1K to 0.75K

Power supply
NOTE
 Make sure the power cables are connected to the R/L1, S/L2, T/L3. (Phase need not be matched.) Never connect the
power cable to the U, V, W of the drive unit. Doing so will damage the drive unit.
 Connect the motor to U, V, W. Turning ON the forward rotation switch (signal) at this time rotates the motor
counterclockwise when viewed from the load shaft.
Connect to the commercial power supply.
Keep these terminals open when using the high power factor converter (FR-HC2) or
power regeneration common converter (FR-CV).
Connect a three-phase squirrel-cage motor.
Connect a brake resistor (FR-ABR, MRS type, MYS type) across terminals P/+ and
PR.
(The brake resistor can not be connected to the 0.1K or 0.2K.)
Connect the brake unit (FR-BU2), power regeneration common converter (FR-CV)
or high power factor converter (FR-HC2).
Remove the jumper across terminals P/+ and P1 and connect a DC reactor.
For earthing (grounding) the drive unit chassis. Must be earthed (grounded).
