Who Should Use This

Manual

This document is intended as a supplementary addition to the 1336 PLUS

6.1 Troubleshooting Guide. This supplement covers the additional information you will need to help troubleshoot or repair an Allen-Bradley

Bulletin 1336 PLUS II Adjustable Frequency AC Drive with A1 - A4

Frames.

This manual is intended for qualified service personnel responsible for troubleshooting and repairing the 1336 PLUS II 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 troubleshooting equipment, equipment protection procedures and methods, and 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 +DC and -DC on

Terminal Block TB1. Do not attempt to service the drive until the bus voltage has discharged to zero volts.

ATTENTION: Potentially fatal voltages may result from improper useage of oscilliscope and other test equipment. The oscilliscope chassis may be at a potentially fatal voltage if not properly grounded. If an oscilliscope is used to measure high voltage waveforms, use only a dual channel oscilliscope in the differential mode with X 100 probes. It is recommended that the oscilliscope 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 PLUS II

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.

Conventions

Introduction

1-5

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.

User Supplied Enclosures

1336 PLUS II drives installed in user supplied enclosures may be mounted within an enclosure or may be mounted to allow the heat sink to extend outside the enclosure

.

Use the information in the 1336 PLUS II User

Manual (1336 PLUS-5.3) to help determine if a possible enclosure sizing or derating problem exists.

To help differentiate parameter names and display 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

AuxiliaryFault.

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.

1336 PLUS-6.16 - September, 2001

1-6

Introduction

Default

When a drive 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 J2 & J4, located on the lower portion of the Main Control Board. This board is identified as L4/4E,

L5/L5E, L6/L6E, L7E, L8E or L9E and provides optional control wiring configurations for a drive Control Interface Board.

Parameter

Parameters are programmable drive functions that define various operating functions or status displays of a drive. Refer to Bulletin 1336 PLUSII User

Manual (1336 PLUS-5.3) for Parameter details.

Press

Press a button on the Human Interface Module to change Parameter settings and drive functions.

True

True refers to a logical true state. For example, a Control Interface signal on

TB3 is true when: L4/L4E contact input is closed, L8E input terminal registers 24V, or L9E input terminal registers 115 VAC.

A hazard of personal injury from automatic restart exists with 2-wire control.

2-wire control uses maintained Run contacts that act as both Run (closed) and Stop (open) devices. Opening the Stop contact (terminal 20) will stop the drive. If this contact is reclosed, any fault will be reset. If a valid Start command is still present, the drive will restart. Only use 2-wire control for applications outlined in NFPA79, "Under Voltage Protection."

If a 3-wire device (i.e. HIM) is also used, pressing the HIM Stop key will also stop the drive. Releasing the Stop key will clear any faults that are present, but the drive will not restart without cycling the Start contact.

Troubleshooting and Error Codes


This chapter helps you trace faults to field-replaceable components.

NOTE: On 1336 PLUS II A1 - A4 Frames, the only replaceable parts are the

Main Control Board and Fans.

Troubleshooting Overview

To troubleshoot a 1336 PLUS II Adjustable Frequency AC Drive, you need a Range DVM, or VOM with a range capacity of at least 1000V.

IMPORTANT: All printed circuit boards, except the Main Control Board assembly, are referenced to negative ground (-bus).

!

ATTENTION: Power circuits are optically isolated from control driver circuits. Power circuit components are “floating” with respect to “ground”. Use only approved methods of isolating test equipment when making measurements in power circuits.

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 +DC and -DC on Terminal Block

TB1. Do Not attempt to service the drive until the bus voltage has discharged to zero volts.

ATTENTION: Potentially fatal voltages may result from improper useage of oscilliscope and other test equipment. The oscilliscope chassis may be at a potentially fatal voltage if not properly grounded. We do not recommend use of an oscilliscope to directly measure high voltages. Use an isolated measuring device with a high voltage probe. Contact Allen-Bradley for recommendations.

ATTENTION: To guard against equipment damage when troubleshooting the drive, always check the following before issuing a Start command:

– Set the Speed Reference to minimum.

– Select the proper motor-rotation direction.

– Disconnect the motor from its mechanical load.

Precautions

Fault Descriptions

!



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.



Fault Display

The LCD display is used to indicate a fault by showing a brief text statement relating to the fault as shown in the following figure. The fault will be displayed until “Clear Faults” is initiated or drive power is cycled. A

Series A (version 3.0) or Series B & up HIM will display a fault when it occurs, no matter what state the display is in. In addition, a listing of past faults can be displayed by selecting “Fault queue” from the Control Status menu (See Chapter 3 of the 1336 PLUS II user manual for more information). Refer to Table 3.A for a listing and description of the various faults.

Figure 3.1 Fault Display

Clearing a Fault

When a fault occurs, the cause must be corrected before the fault can be cleared. After corrective action has been taken, simply cycling drive power will clear the fault. Issuing a valid Stop command from the HIM or Control

Interface option (TB3) will also clear a fault if the {Flt Clear Mode] parameter is set to “Enabled”. In addition, a “Clear Faults” command can be issued anytime from a serial device (if connected).

Contact Description

A schematic representation of contacts CR1-CR4 is shown in Figure 2-5 of the 1336 PLUS II User Manual. When powered these contacts will change state. For Example: During normal operating conditions (no faults present, drive running), the CR3 contacts (default firmware setting) at TB2-13 & 14 are open, and the contacts at TB2-14 & 15 are closed. When a fault occurs, the state of these contacts will change.

Description

This fault indicates that there is not a valid operating frequency. It can be caused by any of the following:

Action

1. [Maximum Freq] is less than

[Minimum Freq].

2. Skip frequencies and skip bandwidth eliminate all operating frequencies.

3. Analog input signal speed reference has been lost. See

[Anlg Signal Loss] and

[4-20mA Loss Sel].

A frequency select parameter has been programmed with an out of range value.

1. Check [Minimum Freq] and [Maximum Freq] parameters.

2. Check [Skip Freq 1], [Skip Freq 2],

[Skip Freq 3] and [Skip Freq Band] parameters.

3. Check for broken wires, loose connections or transducer loss at analog inputs.

Reprogram [Freq Select 1] and/or [Freq

Select 2] with a correct value. If problem persists, replace Main Control

Board or complete drive.

Refer to Table 3.B.

[Fault Data] = 98 – “3 Wire” is selected as the [Input Mode] and one or more digital inputs are programmed to “Run Reverse” (2 wire action).

The DC bus ripple has exceeded the value in [Phase Loss Level].

Reprogram the digital inputs or select

“2 Wire” as the [Input Mode].

1. If the drive is operated on single-phase, the load derating level has been exceeded.

2. Check incoming power for a missing phase/blown fuse.

1. Verify connections between motor and load.

[Load Loss Detect] is set to

“Enabled” and the drive output torque current was below [Load

Loss Level] for a time period greater than [Load Loss time].

An overrun of the 2.5ms control loop has occurred.

2. Verify level and time requirements or disable [Load Loss Detect].

Drive unsuccessfully attempted to reset a fault and resume running for the programmed number of

[Reset/Run Tries].

A fault has been detected originating from the Control Board.

Current remained over [Current

Limit] setting (parameter 36) for more than 4 seconds.

An analog option board with thermistor input is installed and the value at the terminals is less than

60 ohms or greater than 3300 ohms.

Check all connections to the Main Control Board. Replace the board or complete drive as needed.
