Consider any of the following measures:
1) Use a motor with 1300V insulation.
2) Connect an output circuit filter (option) to the output
terminals of the drive.
3) Take steps to minimize the wiring length between
the drive and motor .
(3) DC reactor terminals, P1 and P (+)
1) Remove the jumper bar from terminals P1 and P(+).
2) Connect a dc reactor (option) to terminals P1 and
P(+).
NOTE: If a dc reactor is to be connected to a braking
resistor, attach both wires of the dc reactor and braking
resistor together to terminal P(+). (See next page)
Do not remove the jumper bar if a dc reactor is not used.
Figure 2.6 DC Reactor Connection
(4) Braking resistor terminals, P(+) and DB
NOTE: Do not connect a braking resistor to any drive
with a rated capacity of 1/8 or 1/4 hp. (If connected, the
braking resistor will not work.)
1) Connect terminals P and DB of the built-in braking
resistor (available to order) or external braking resis-
tor (option) to terminals P(+) and DB on the main
circuit terminal block.
2) When using an external braking resistor, arrange the
drive and braking resistor to keep the wiring length
to 5 m or less, and twist the two wires or route them
together in parallel.
When a dc reactor is not to be connected together
with the braking resistor
1) Remove the screws from terminals P1 and P(+),
together with the jumper bar.
2) First connect the wire from terminal P of the braking
resistor to terminal P(+), then the jumper bar, and
secure them with the screw removed in 1) above.
3) Tighten the screw on terminal P1.
4) Connect the wire from terminal DB of the braking
resistor to the DB of the drive.
Figure 2.7 Braking Resistor Connection without DC Resistor
When connecting a dc reactor together with the
braking resistor
1) Remove the screw from terminal P(+).
2) Overlap the dc reactor wire and braking resistor
wire (P) as shown at left and then secure them to
terminal P(+) of the drive with the screw.
3) Connect the wire from terminal DB of the braking
resistor to terminal DB of the drive.
4) Do not use the jumper bar.
