Preface
Manual Objective
The information in this manual is designed to help repair an
Allen-Bradley Bulletin 1336 FORCE Adjustable Frequency AC
Drive with ratings B300 – B600, C300 – C600, and BX250.
Who Should Use
This Manual
This manual is intended for qualified service personnel responsible
for repairing the 1336 FORCE Adjustable Frequency AC Drive. You
should:
• Read this entire manual before performing maintenance or repairs
to drives.
• Have previous experience with, and basic understanding of,
electrical terminology, procedures, required equipment,
equipment protection procedures and methods, and safety
precautions.
This manual describes equipment and disassembly procedures. You
begin with general illustrations and end with greater detail
concerning replacement parts and part locations on the drives. Later
chapters may refer you back to earlier chapters for information on
basic equipment and steps necessary to perform detailed diagnostics
and part replacement.
Safety Precautions
!
ATTENTION: Some printed circuit boards and drive
components may contain hazardous voltage levels.
Remove and lock out power before you disconnect or
reconnect wires, and before you remove or replace
fuses and circuit boards. Verify bus voltage by
measuring the voltage between the Negative Capacitor
Bus and both ends of all three 350 amp fuses. An open
fuse does not show voltage across both ends of the
fuse. Failure to measure voltage at both ends of the
fuses may result in death or serious injury. Refer to
Figure 2.5. Do not attempt to service the drive until the
bus voltage has discharged to zero volts.

Electrostatic Discharge
Precautions
!
ATTENTION: Potentially fatal voltages may result
from improper usage of oscilloscope and other test
equipment. The oscilloscope chassis may be at a
potentially fatal voltage if not properly grounded. If an
oscilloscope is used to measure high voltage
waveforms, use only a dual channel oscilloscope in the
differential mode with X 100 probes. It is
recommended that the oscilloscope be used in the A
minus B Quasi-differential mode with the oscilloscope
chassis correctly grounded to an earth ground.
ATTENTION: Only personnel familiar with the
1336 FORCE Adjustable Frequency AC Drive and
associated machinery should plan or implement the
installation, start-up and subsequent maintenance of the
system. Failure to comply may result in personal injury
and/or equipment damage.
ATTENTION: This assembly contains parts and
sub-assemblies that are sensitive to electrostatic
discharge. Static control precautions are required when
servicing this assembly. Component damage may result
if you ignore electrostatic discharge control procedures.
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.
Electrostatic discharge generated by static electricity can damage the
complimentary metallic oxide semiconductor devices on various
drive boards. It is recommended that you perform these procedures
to guard against this type of damage when circuit boards are
removed or installed:
• Wear a wrist-type grounding strap that is grounded to the drive
chassis.
• Attach the wrist strap before removing the new circuit board from
the conductive packet.
• Remove boards from the drive and immediately insert them into
their conductive packets.

Drive Rating Qualifications
Several factors can affect drive rating. If more than one factor exists,
derating percentages must be multiplied. For example, if a 14-amp
drive is installed at a 2km (6,600 ft.) altitude and has a 2%
high-input line voltage, the actual amp rating is:14 x 94% altitude
derating x 96% high-input line derating = 12.6 amps

Preface
Conventions
To help differentiate parameter names and display text from other
text in this manual, the following conventions will be used:
• Parameter Names will appear in [brackets].
• Display Text will appear in “quotes”.
The following is a list of conventions used throughout this manual,
and definitions of the conventions. For a list of terminology and
definitions, refer to the Glossary in the back of this manual.
Auxiliary Input
The Auxiliary Input is a terminal connection on the Control Interface
Board. This connection provides an external input for use as an
Auxiliary Interlock. Unless this interlock is closed, the drive will be
faulted with an Auxiliary Fault.
Auxiliary Interlock
The Auxiliary Interlock is a user supplied circuit consisting of reset,
overload, or other interlocking circuitry. The Interlock is wired to the
drive Auxiliary input.
Bit
A bit is a single character or status point used in programmable
logic. Eight bits form a BYTE, 16 bits form a word. Drive
parameters are actually eight bits or 16 bit words.
Check
To check means to examine either the physical condition of
something or the setting of some control, such as a Parameter.
Checking a drive board or component may also require
measurements and tests.
Connector
A connector connects one drive board to another. Connectors come
in two designs, male and female. Male connectors are stationary and
contain pins, which are sometimes joined by jumpers. Female
connectors are at the ends of wires or ribbon cables and plug into
male connectors.
Publication 1336 FORCE-6.15 – August, 1999
Preface
P–9
Default
When a drive function defaults, it automatically changes to a
pre-programmed setting.
Enable Input
The Enable Input is a terminal connection on the Control Interface
Board. This connection provides an external input to enable or
disable the Drive Output section. It must be true to permit the drive
to operate.
False
False refers to a logical false state. For instance, a Control Interface
signal on TB3 is false when the input contact is open or the
appropriate voltage is not applied to the Control Interface Board.
Jumper
A jumper completes a circuit between two pins within a male
connector on a drive board. In the absence of certain optional
equipment using female connectors, jumpers are applied to certain
pins within a male connector to complete specific and necessary
circuits.
Control Interface Board
A Control Interface Board plugs into connectors J7 and J9, located
on the lower portion of the Standard Adapter Board. This board is
identified as L4, L5, or L6 and provides optional control wiring
configurations for a drive.
Parameter
Parameters are programmable drive functions that define various
operating functions or status displays of a drive. Refer to Bulletin
1336 FORCE Adjustable Frequency AC Drive User Manual for
Parameter details.
Press
Press a button on the Human Interface Module to change Parameter
settings and drive functions.
Publication 1336 FORCE-6.15 – August, 1999
P–10
Preface
True
True refers to a logical true state. For instance, a Control Interface
signal on TB3 is true when: L4 contact input is closed, L5 input
terminal registers 24V, or L6 input terminal registers 115V AC.

!
!
All printed circuit boards, except the Main Control
Board assembly, are referenced to negative ground
(–bus).
ATTENTION: Some printed circuit boards and drive
components may contain hazardous voltage levels.
Remove power before you disconnect or reconnect
wires, and before you remove or replace fuses and
circuit boards. Verify bus voltage by measuring the
voltage between the Negative Capacitor Bus and both
ends of all three 350 amp fuses. An open fuse does not
show voltage across both ends of the fuse. Failure to
measure voltage at both ends of the fuses may result in
death or serious injury. Refer to Figure 2.5. Do not
attempt to service the drive until the bus voltage has
discharged to zero volts.
ATTENTION: This assembly contains parts and
sub-assemblies that are sensitive to electrostatic discharge.
Static control precautions are required when servicing this
assembly. Component damage may result if you ignore
electrostatic discharge control procedures. If you are not
familiar with static control procedures, reference
Allen-Bradley Publication 8000–4.5.2, Guarding Against
Electrostatic Discharge, or any other applicable ESD
protection handbook.

HIM Removal
!
ATTENTION: Some voltages present behind the
drive front cover are at incoming line potential. To
avoid an electric shock hazard, use extreme caution
when removing/replacing the HIM.
For handheld operation, the module can be removed and located up
to 10 meters (33 feet) from the drive.
Important: Power must be removed from the drive or Bit 1 of the
[Logic Mask] parameter must be set to “0” to allow
removal of the HIM module without causing a
Communication Fault. Setting Bit 1 of the [Logic
Mask] parameter to “0” allows HIM removal while
power is applied to the drive. Note that this also
disables all HIM control functions except Stop.
Important: To remove the module:
1. Ensure that power has been removed or [Logic Mask] has been
set to “0”.
2. Take the drive front cover off and simply slide the module down
and out of its cradle. Remove cable from module.
3. Connect the appropriate cable between the HIM and the
Communications Port (Adapter 2, 3, 4, or 5).
4. Reverse the above steps to replace the module. Apply power or reset
Bit 1 of the [Logic Mask] parameter to “1” to enable HIM control.
HIM Operation
When power is first applied to the drive, the HIM will cycle through
a series of displays. These displays will show drive ID and
communication status. Upon completion, the Status Display (refer to
Figure 1.9) will be shown. This display shows the current status of
the drive (i.e. Stopped, Running, etc.) or any faults that may be
present (Not Enabled, etc.). Refer to the 1336 FORCE Field Oriented
Control User Manual.

Drive Tools
Drive Tools software is a Windows 3.1 compatible family of
application programs allowing the user to perform programming,
monitoring, and diagnostic operations on Allen-Bradley AC and DC
digital drive products. The software consists of five Windows
applications. For operation, refer to the Product Data Drive Tools
Software manual.
Control Firmware Function
All control functions in the 1336 FORCE are performed through the
use of parameters that can be changed with a programming terminal
or Drive Tools. Refer to an overview Block Diagram of the Control
Firmware Function in the 1336 FORCE Field Oriented Control User
Manual.
Feedback information is derived from hardware devices as part of
the process equipment used. Analog signals are converted to digital
signals for use by the drive. Control signals may be provided to the
drive by one of two Adapter Boards.
All setup and operation information used by the drive is stored in a
system parameter table. Every parameter, including Setup and
Configuration parameters (Sources and Sinks), has an entry in the
parameter table. For example, parameter 101 is named the “Velocity
Reference 1 HI (whole)” parameter and contains a number value
representing the velocity reference. The velocity reference can
originate from an external control device such as a potentiometer
connected to the analog input of an Adapter board or a signal coming
in via RIO from a PLC. Refer to the 1336 FORCE User Manual,

Disassembly and Access
Procedures
Chapter Objectives
This chapter describes general disassembly procedures required to
access internal drive components.
Disassembly and
Access Overview
!
!
ATTENTION: Some printed circuit boards and drive
components may contain hazardous voltage levels.
Remove and lock out power before you disconnect or
reconnect wires, and before you remove or replace
fuses and circuit boards. Verify bus voltage by
measuring the voltage between the Negative Capacitor
Bus and both ends of all three 350 amp fuses. An open
fuse does not show voltage across both ends of the
fuse. Failure to measure voltage at both ends of the
fuses may result in death or serious injury. Refer to
Figure 2.5. Do not attempt to service the drive until the
bus voltage has discharged to zero volts.
ATTENTION: Servicing energized industrial control
equipment can be hazardous. Electrical shock, burns,
or unintentional actuation of controlled industrial
equipment may cause death or serious injury. Follow
the safety-related practices of NFPA 70E, Electrical
Safety for Employee Workplaces, when working on or
near energized equipment. Do not work alone on
energized equipment.

Disassembly and Access Procedures
Electrostatic Discharge
Precautions
!
ATTENTION: This assembly contains parts and
sub-assemblies that are sensitive to electrostatic
discharge. Static control precautions are required when
servicing this assembly. Component damage may result
if you ignore electrostatic discharge control procedures.
If you are not familiar with static control procedures,
reference Allen-Bradley Publication 8000–4.5.2,
Guarding Against Electrostatic Discharge, or any other
applicable ESD protection handbook.
Electrostatic discharge generated by static electricity can damage the
complimentary metallic oxide semiconductor devices on various
drive boards. It is recommended that you perform these procedures
to guard against this type of damage when circuit boards are
removed or installed:
• Wear a wrist-type grounding strap that is grounded to the chassis.
• Attach the wrist strap before removing the new circuit board from
the conductive packet.
• Remove boards from the drive and immediately insert them into
their conductive packets.
Tools
You need the following tools to disassemble and assemble the drive:
• Pliers
• Phillips screwdrivers (small, medium, and large)
• Standard screwdrivers (small, medium, and large)
• Metric socket set up to 19 mm
• Torque wrench to 34 N-m or 280 in.-lbs
• Torque screwdriver to 10 N-m or 80 in.-lbs
• Nylon tie wraps

Fastener Torque
Specifications
Torque Sequence
When mounting components to a drive’s heat sink, component-fastener
torque sequences and tolerances are crucial to component-to-heat sink
heat dissipation.
!
ATTENTION: Component can be damaged if
temporary tightening procedure is not performed to
specification.
The following illustrates temporary and final tightening sequences
for components fastened to a heat sink using two, four, and six
screws. Temporary torque is 1/3 (33%) of final torque, except
six-point mountings, which require 0.5 N-m (4 in.-lb). The numeric
illustration labels are for your assistance. Drive components do not
carry these labels.

ATTENTION: These assemblies weigh about 500
pounds each. Before you pull either one from the drive,
you must have a platform in place to hold the assembly.
You cannot remove the assembly without a platform. The
top of the platform must be even with the assembly’s
track. The platform must be strong enough to support the
assembly and the personnel servicing the drive. The
marketing department at Allen-Bradley can provide plans
for a suitable platform. Refer to the back cover of this
manual for the address and telephone number.
ATTENTION: To remove either the Inverter
Housing Assembly or the Capacitor Bank Assembly
safely requires two persons. Attempting to remove
either assembly by yourself may result in death or
serious injury.
!
ATTENTION: Do not remove both the Inverter
Housing and the Capacitor Bank assemblies at the
same time.
!
ATTENTION: Replace all guards before applying
power to the drive. Failure to replace guards may result
in death or serious injury.
The three main parts of this drive are the PC Board Mounting Frame,
the Inverter Housing Assembly, and the Capacitor Bank Assembly.
Some procedures in this manual require access to these assemblies
and refer to this section.
Each assembly has wheels that roll in tracks built into the base of the
drive. Chocks bolted into the tracks prevent assembly movement. The
drive itself also has wheels, built into the main framework of the drive.
Because of the size, weight, and physical characteristics of the drive,

Chapter Objectives
The following tests help you troubleshoot B300 – B600, C300 –
C600, and BX250 drives.
Component Test
Overview
In some cases, different tests troubleshoot components of the same
name.
These similar tests vary according to the rating of the drive being
tested. Verify that the rating on the drive matches the rating for the
test you are performing.
The part replacement procedures in this chapter assume that the drive
you are servicing either has no enclosure or that the enclosure is
open. For more information on opening the Drive Enclosure, refer to
Chapter 2 – Disassembly and Access Procedures, Opening the Drive
Enclosure.
!
!
ATTENTION: Some printed circuit boards and drive
components may contain hazardous voltage levels.
Remove and lock out power before you disconnect or
reconnect wires, and before you remove or replace
fuses and circuit boards. Verify bus voltage by
measuring the voltage between the Negative Capacitor
Bus and both ends of all three 350 amp fuses. An open
fuse does not show voltage across both ends of the
fuse. Failure to measure voltage at both ends of the
fuses may result in death or serious injury. Refer to
Figure 2.5. Do not attempt to service the drive until the
bus voltage has discharged to zero volts.
ATTENTION: Servicing energized industrial control
equipment can be hazardous. Electrical shock, burns,
or unintentional actuation of controlled industrial
equipment may cause death or serious injury. Follow
the safety-related practices of NFPA 70E, Electrical
Safety for Employee Workplaces, when working on or
near energized equipment. Do not work alone on
energized equipment.

Electrostatic Discharge
Precautions
!
ATTENTION: This assembly contains parts and
sub-assemblies that are sensitive to electrostatic
discharge. Static control precautions are required when
servicing this assembly. Component damage may result
if you ignore electrostatic discharge control procedures.
If you are not familiar with static control procedures,
reference Allen-Bradley Publication 8000-4.5.2,
Guarding Against Electrostatic Discharge, or any other
applicable ESD protection handbook.
Electrostatic discharge generated by static electricity can damage the
complimentary metallic oxide semiconductor devices on various
drive boards. It is recommended that you perform these procedures
to guard against this type of damage when circuit boards are
removed or installed:
• Wear a wrist-type grounding strap that is grounded to the chassis.
• Attach the wrist strap before removing the new circuit board from
the conductive packet.
• Remove boards from the drive and immediately insert them into
their conductive packets.

Chapter Objective
This chapter describes procedures required to replace drive
components. This chapter references Chapter 2 – Disassembly and
Access Procedures for basic drive component access.
Part Replacement
Overview
The part replacement procedures in this chapter assume that the drive
you are servicing either has no enclosure or that the enclosure is
open. For more information on opening the Drive Enclosure, refer to
Chapter 2 – Disassembly and Access Procedures, Opening the Drive
Enclosure.
Safety Precautions
!
ATTENTION: Some printed circuit boards and drive
components may contain hazardous voltage levels.
Remove power before you disconnect or reconnect
wires, and before you remove or replace fuses and
circuit boards. Verify bus voltage by measuring the
voltage between between the Negative Capacitor Bus
and both ends of all three 350 amp fuses. An open fuse
does not show voltage across both ends of the fuse.
Failure to measure voltage at both ends of the fuses may
result in death or serious injury. Refer to Figure 2.5. Do

Electrostatic Discharge
Precautions
!
ATTENTION: This assembly contains parts and
sub-assemblies that are sensitive to electrostatic
discharge. Static control precautions are required when
servicing this assembly. Component damage may result
if you ignore electrostatic discharge control procedures.
If you are not familiar with static control procedures,
reference Allen-Bradley Publication 8000–4.5.2,
Guarding Against Electrostatic Discharge, or any other
applicable ESD protection handbook.
Electrostatic discharge generated by static electricity can damage the
complimentary metallic oxide semiconductor devices on various
drive boards. It is recommended that you perform these procedures
to guard against this type of damage when circuit boards are
removed or installed:
• Wear a wrist-type grounding strap that is grounded to the chassis.
• Attach the wrist strap before removing the new circuit board from
the conductive packet.
• Remove boards from the drive and immediately insert them into
their conductive packets.
For a list of tools required, tightening sequences, and fastener torque
specifications, refer to Chapter 2 – Disassembly and Access
Procedures, Fastener Torque Specifications.

AC Contactor: An alternating-current (AC) contactor is designed
for the specific purpose of establishing or interrupting an AC Power
circuit.
Adjustable Speed: The concept of varying the speed of a motor,
either manually or automatically. The desired operating speed (set
speed) is relatively constant regardless of load.
Adjustable Speed Drive (Electrical): The adjustable speed drive is
comprised of the motor, drive controller and operator’s controls
(either manual or automatic).
Ambient Temperature: The temperature of the medium (air, water,
earth) into which the heat of the equipment is dissipated.
Base Speed: The manufacturer’s nameplate rating where the motor
will develop rated power at rated load and voltage. With DC drives,
it is commonly the point where full armature voltage is applied with
full-rated field excitation. With AC systems, it is commonly the point
where 60 Hz is applied to the induction motor.
BR: Refer to Bridge Rectifier.
Braking: A method of stopping or reducing the time required to
stop an AC motor, and can be accomplished in several ways:
1. DC-Injection braking (AC drives) Ċ A method which produces
electromagnetic braking forces in the motor by removing 2 AC
motor (stator) phases and injecting DC current. The result is a
linear braking characteristic (ramp) that does not diminish with
motor speed. Application is normally limited to 10–20% of rated
motor speed due to increased heating in the rotor.
2. Dynamic braking (AC drives) Ċ A method which produces
electromagnetic braking forces in the motor by dissipating
generated power into the DC bus through a resistive load.
Braking force remains constant and is only limited by the thermal
capacity of the resistors. The result is a linear braking
characteristic (ramp) that does not diminish with motor speed.
3. Regenerative braking Ċ A method which produces
electromagnetic braking forces in the motor by electronically
controlling the return of generated power to the AC supply. The
result is a controllable linear braking characteristic (ramp) that
does not diminish with motor speed.
G–2
Glossary
4. Motor-mounted or separately-mounted brake Ċ A

semiconductor device in which an electric field controls the
conductance of a channel under a metal electrode called a gate.

steps or jerks from one position to another during shaft revolution.
Cogging is most pronounced at low motor speeds and can cause
objectionable vibrations in the driven machinery.

frequency is varied. This speed range produces motor performance
similar to a DC drive’s constant horsepower range.

intermediate circuit, an inverter, and a control unit.
Counter Electromotive Force (CEMF): The product of a motor
armature rotating in a magnetic field. This generating action takes
place whenever a motor is rotating. Under stable motoring conditions
the generated voltage (CEMF) is equal to the voltage supplied to the
motor minus small losses. However, the polarity of the CEMF is
opposite to that of the power being supplied to the armature.
Current Limiting: An electronic method of limiting the maximum
current available to the motor. This is adjustable so that the motor’s
maximum current can be controlled. It can also be preset as a
protective device to protect both the motor and the control from
extended overloads.
DC Boost: Compensates for the voltage drop across the resistance
of an AC motor circuit and the resulting reduction in torque.
DC Bus: A drive’s power structure that transmits a rectified AC line
power from the bridge rectifier to the output transistors.

accurately the motor speed can be maintained. It is the percentage of
change in speed between full load and no load. The ability of a drive

both the characteristics of the load being driven and electrical time
constants in the drive regulator circuits.
Surge Protection: The process of absorbing and clipping voltage
transients on an incoming AC power line or control circuit. Surge
protectors include MOVs (Metal Oxide Varistors) and specially
designed R-C networks.
Synchronous Speed: The speed of an AC induction motor’s
rotating magnetic field. It is determined by the frequency applied to
the stator and the number of magnetic poles present in each phase of
the stator windings. Mathematically, it is expressed as: Sync Speed
(rpm) = 120 x Applied Freq. (Hz) / Number of poles per phase.
Torque: A turning force applied to a shaft, tending to cause rotation.
Torque is equal to the force applied, times the radius through which
it acts. Torque is measured in pound-feet, ounce-inches,
Newton-meters, or gram-centimeters.
