Introduction
Manual Objectives This document is intended as a supplementary addition to the 1336
FORCE 5.12 User Manual. This supplement covers the additional
information you will need to install, program, start up and maintain a
1336 FORCE Master/Slave parallel drive combination.
Who Should Use This Manual This manual is intended for qualified service personnel who have
experience setting up and servicing 1336 FORCE AC Drives. You
must have previous experience with and a complete understanding of
electrical terminology, programming procedures, required equipment
and safety precautions before attempting any service on a 1336
FORCE Master/Slave AC Drive.
System Overview The 1336 FORCE Master/Slave Parallel AC Drive uses parallel
inverters in applications where the required power is greater than our
single largest drive can provide. This 1336 FORCE parallel drive
combination is available in 1000, 1300 and 1600 HP versions.
Master/Slave drives are available as G or H frame drives in matched
500, 650 or 800 HP combinations. This system utilizes two inverters
to supply power to a single motor with two sets of isolated stator
windings as illustrated in Figure 1. The inverters are connected to a
common converter (common bus) with each inverter operating its
own system level functions (communications, precharge etc.).
!
ATTENTION: Only qualified personnel familiar with
the 1336 FORCE Master/Slave drive system and the
associated machinery should plan or implement the
installation, start-up, and subsequent maintenance of the
Drive. Failure to comply may result in personal injury
and/or equipment damage.
ATTENTION: An incorrectly applied or installed
Drive can result in component damage or a reduction in
product life. Wiring or application errors such as
undersizing the motor, incorrect or inadequate AC
supply or excessive ambient temperatures may result in
damage to the Drive or motor.
ATTENTION: This Drive contains ESD (Electrostatic
Discharge sensitive parts and assemblies. Static control
precautions are required when installing, testing,
servicing or repairing this assembly. Component
damage may result if ESD control procedures are not
followed. If you are not familiar with static control
procedures, reference Allen-Bradley Publication 8000-
4.5.2, Guarding Against Electrostatic Damage or any
other applicable ESD protection handbook.
