Dynamic Braking Kit

Model 34C473

For use with 5, 7Ć1/2 and 10 HP

ThreeĆPhase Input

General Purpose AĆC VKSR Drives

Before installing and/or adjusting this kit, the quali

fied electrical maintenance person who is familiar

with

this type of equipment and the hazards involved

should read this entire instruction sheet.

DESCRIPTION

The Reliance Electric Dynamic Braking (DB) Kit is deĆ

signed

to provide rapid

deceleration of the drive motor

and/or

enable the AĆC V

KSR

Drive Controller to provide

150% intermittent braking to the motor. The kit dissiĆ

pates,

in the form of heat, the power regenerated by the

motor during deceleration or intermittent overhauling

loads.

The power is dissipated by resistors mounted in

the NEMA

side (right side) of the AĆC V

S Drive Con

troller

cabinet.

This kit also provides adjustable motoring and regenĆ

erative current limit circuitry. The adjustment range of

the motoring current control is approximately 40 to

150%

of the drive controller fullĆload current (not of the

motor

fullĆload current rating). The adjustment range of

the

regeneration current control is approximately 80 to

150% of the drive controller fullload current (not of the

motor fullĆload current rating). The use of this kit does

not affect the operation of the drive's instantaneous

electronic

trip current protection.

CAUTION:

Should the regenerative

current limit be

set

below a particular motor's

minimum current lev

el, the regenerative current limit circuitry may proĆ

hibit

the motor

from decelerating. Reset the regen

erative current limit as described under ADJUSTĆ

MENTS"

in this instruction sheet.

CAUTION:

NOT

operate the controller with

the

Resistor Assembly and DB

Base Driver Assem

bly

connected and the CLSA Board removed. Dam

age

to equipment will occur

. If it is desired to oper

ate

the controller without dynamic braking, removal

of the threeĆpin plug (wire harness 608808Ć63TD)

from the DB Base Driver Assembly PC Board will

disable

this kit.

The

DB Base Driver PC Board includes a light emitting

diode

(LED) that indicates dynamic braking action. Dur

ing

normal deceleration, the LED will cycle ON and OFF

high rates of deceleration, the LED will appear to be

continuously

The following are design specifications for this kit:

DB Resistor rating: 500 watts

3: 6 starts/stops per minute from 1800 RPM

6: 3 starts/stops per minute from 1800 RPM
