R/L1,
S/L2,
T/L3
AC power input
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).
U, V, W
Drive unit output
Connect a PM motor.
P/+, PR
Brake resistor connection
Connect a brake resistor (FR-ABR, MRS type, MYS type) across terminals P/+ and
PR. (The brake resistor cannot be connected to the 0.2K.)
P/+, N/-
Brake unit connection
Connect the brake unit (FR-BU2), power regeneration common converter (FR-
CV) or high power factor converter (FR-HC2).
P/+, P1
DC reactor connection
Remove the jumper across terminals P/+ and P1 and connect a DC reactor.
When a DC reactor is not connected, the jumper across terminals P/+ and P1
should not be removed.
Earth (Ground)
For earthing (grounding) the drive unit chassis. Must be earthed (grounded).
FR-D720-0.2K to 0.75K-G
FR-D720-1.5K to 3.7K-G
FR-D740-0.4K to 3.7K-G
NOTE
Make sure the power cables are connected to the R/L1, S/L2, and T/L3. (Phase need not be matched.) Never connect
the power cable to the U, V, and 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. The rotation direction of the output shaft may differ depending on
the reduction gear. Check the motor specifications.
