Connecting the Braking Resistor (Mounting 3G3IV-PERF)
A
Braking Resistor that mounts to the Inverter can be used with 200-V and 400-V Class Inverters with outputs
from
0.4 to 11 kW.
Connect
the braking resistor as shown in Fig 2.16.

n
Connecting the Braking Resistor Unit (3G3IV-PLKB
@ @ @ @
) and Braking Unit (3G3IV-
PCDBR
@ @ @ @
)
Connect
the Braking Resistor Unit and Braking Unit to the Inverter as shown in the Fig 2.17.
A
Braking Resistor that mounts to the Inverter can also be used with Inverters with outputs from 0.4 to 11 kW.
L8-01
is used when a braking resistor without thermal overload relay trip contacts (3G3IV-PERF @ mounted
to
Inverter) is connected.
The
Braking Resistor Unit cannot be used and the deceleration time cannot be shortened by the Inverter if L3-
04
is set to 1 (i.e., if stall prevention is enabled for deceleration).

L8-01
(Protect selection for internal DB resistor)
1
(Enables overheat protection)
L3-04
(Stall prevention selection during deceleration)
(Select
either one of them.)
0
(Disables stall prevention function)
3
(Enables stall prevention function with braking resistor)
IMPORTANT
The braking resistor connection terminals are B1 and B2. Do not connect to any other terminals. Connecting
to any terminals other than B1 or B2 can cause the resistor to overheat, resulting in damage to the equip-
ment.
