Chapter 3 Overview The 1336VT is an AC adjustable frequency drive designed for use with a standard, three-phase induction motor. The standard control is designed as a constant torque, adjustable speed control with 115% overload capability and is adaptable through programming to handle a wide variety of applications. The 1336VT provides an exceptional output voltage and current waveform. Special considerations however, must be taken when applying an inverter to an existing motor.
Chapter 3 Overview Shown below are typical variable torque curves plotting torque versus speed. At slow speeds, if torque requirements continuously exceed levels shown below (10 minutes or longer), a motor rated for the required speed and torque range must be used. To guard against mechanical problems, it is recommended that the entire drive train machinery be checked for various limitations due to the range of the Bulletin 1336VT.

Chapter 4 Specifications Required Control Inputs As a minimum requirement for drive operation, the following five control inputs must be present to operate the drive: Start A momentary True input will start the drive. The drive will continue to run until a stop input is issued or a drive fault occurs. A start input may come from: • The optional FA2, RP2 or RP3 control panel start pushbutton. • A user supplied N.O. contact or start pushbutton connected to the optional L1, L2, or L3 Logic Interface Board.
Chapter 4 Specifications Required Control Inputs (cont.) Speed Reference Speed reference sets the drive operating frequency. A speed reference input may come from: • A Control Panel speed potentiometer. • A user supplied 10kΩ remote speed potentiometer connected to terminal block TB2. Refer to Chapter 6 — Wiring. • A 4-20mA analog signal connected to terminal block TB2. Refer to Chapter 6 — Wiring. • A 0-10V DC analog signal connected to terminal block TB2. Refer to Chapter 6 — Wiring.
Chapter 4 Specifications Optional Control Inputs Reverse Reverse changes direction of motor rotation. Reverse inputs may come from: • A Control Panel direction pushbutton. • The optional L1, L2 or L3 Logic Interface Board. Refer to Appendix A — Logic Interface Options and the 1336-MOD-L1, L2 or L3 instruction manual. • The optional G2 Remote I/O Interface Board. Refer to the 1336-MOD-G2 instruction manual. Jog Jog jogs the drive at a pre-programmed jog speed.

Chapter 4 Specifications Programmable Parameters 4-10 The 1336VT drive logic uses a set of 90 user parameters to select and control drive operation. Seventy-one of these parameters are accessible through any of the Programming and Display Panels. All 90 are accessible through the Serial Port.
Chapter 5 Installation General Installation Requirements ! ATTENTION: An incorrectly applied or installed system can result in component damage or reduction in product life. The most common causes are: • Wiring the AC line to drive output or control terminals. • Improper bypass or output circuits not approved by Allen-Bradley. • Output circuits which do not connect directly to the motor. • Incorrect or inadequate AC supply. • Excessive ambient temperature.

Chapter 6 Wiring General Wiring Procedures ! ! ATTENTION: Do not proceed without reading the information on this page. Failure to understand procedures and hazards may result in personal injury or equipment damage. ATTENTION: An incorrectly applied or installed system can result in component damage or reduction in product life. The most common causes are: • Wiring the AC line to drive output or control terminals. • Improper bypass or output circuits not approved by Allen-Bradley.
Chapter 6 Wiring Input Power Conditioning Typically, the 1336VT is suitable for direct connection to a correct voltage, three phase, AC power line. There are, however, certain power line conditions which will greatly increase the possibility of drive input power component malfunction. To reduce the possibility of these malfunctions, a line reactor or isolation type transformer may be required. The basic rules for determining if a line reactor or isolation type transformer is required are as follows: 1.
Chapter 6 Wiring Wire Group Numbers The following chart identifies general wire categories that will be encountered when installing the 1336VT. Each category has an associated wire group number that is used in the following sections to identify the wire to be used. Application and signal examples along with the recommended type of cable for each group is provided. A matrix providing the recommended minimum spacing between different wire groups run in the same tray or separate conduit is also provided.
Chapter 6 Wiring Terminal Block TB1 Power Wiring Input and output power connections are marked on terminal block TB1, a ten position terminal block on the drive backpanel. For maintenance and setup procedures, the drive may be operated without a motor connected. Important: 1. The 1336VT does not provide input power short circuit fusing. Specifications for the recommended fuse size and type to provide drive input power protection against short circuits are provided on the following pages.
Chapter 6 Wiring ! ATTENTION: 1. Any disconnecting means wired to drive output terminals M1, M2 and M3 must be capable of stopping the drive if opened during drive operation. If opened during drive operation, the drive will continue to produce output voltage into an open motor circuit causing a potential shock hazard. 2. The start/stop control circuitry in the 1336VT includes solid-state components.

Chapter 9 Startup Initial Operation Step 14 - Motor Disconnected (cont.) Freq PR While the drive is running, open the Enable Signal at TB3, Terminal 30. The drive will stop and display the Enable Lost Code – – – - -. Restore the enable signal. Step 15 Auxiliary Interlock Check Start Restart the drive. With the drive running, open the auxiliary interlock signal at TB3, Terminal 28. The drive will stop and display the Enable Fault F02 – –.
Chapter 9 Startup Initial Operation - Motor Disconnected (cont.) Step 18 Preset Frequencies If preset frequencies are not to be used, go to Step 19. If Preset Frequencies 1-3 are used, set Parameter 72 (Activate Parameters 73-76) to 0 (Off). With the drive running, select each of the preset frequencies by closing the inputs at Terminals 24 and 26 of TB3. As each preset frequency is selected, the drive will ramp to that frequency and remain there until the next frequency is selected.
Chapter 9 Startup Initial Operation - Motor Connected ! ATTENTION: The following steps may cause motor rotation in an unknown direction. To guard against equipment damage, always disconnect the motor from the load before proceeding. Step 21 Reapply power to the drive.

Step 24 With the drive operating at 1/4 speed or greater: Stop Stop the drive and verify that the stopping mode selected by Parameter 10 occurs. Step 25 Stop PR Stop the drive.
Chapter 9 Startup Initial Operation - Motor Connected (cont.) Step 26 If the drive is to receive control signals and data from a programmable controller via the MOD-G2 Remote I/O communication option, the programmable controller must be tested with the motor disconnected from the load. Prepare all drive control signal interfaces and Remote I/O option for programmable controller operation. Refer to Remote I/O Instruction Manual. Reset appropriate drive control parameters 5-50 and 72-86.
Chapter 9 Startup Initial Operation - Motor Connected (cont.) Step 27 (cont.) Apply power. Prepare to operate the drive and motor under actual control and load conditions.
