1336 PLUS Drives Selection Guide
Offering various microprocessor-controlled devices for controlling three-phase industrial applications, Allen Bradley 1336 Drives PLUS Drives are high-performance adjustable frequency AC drives. For programming ease, each comes with a handheld terminal, and the output voltage adjusts according to the motor parameters that match its frequency output. Thus, this piece of writing focuses on analyzing their technical specifications.
The 1336 PLUS drives are AC motors with integrated microprocessors, offering superior vector control without needing sensors. These reliable, efficient, and cost-effective drives are ideal for precise torque and speed management and boast a broad voltage input range of 200 to 600 volts and a frequency of up to 400 Hz. The enclosures are customizable too: choose from open frame (IP00), NEMA Type 1 (IP20), or NEMA Type 12 (IP54) boxes; one can also opt for an IP65 NEMA Type 4 option if needed. Furthermore, there is a selection of frame sizes ranging from A1 to G, with motor power inputs between 0.37 kilowatts (0.5 horsepower) and 448 kilowatts (600 horsepower). This wide variety of specifications supports variable and constant torque applications, with ratings up to 115% and 150% of the entire load amperage.
AC Supply Source Along with Input Power Conditioning
When the 1336 PLUS drives are used on a circuit with up to 200,000 RMS symmetrical amperes and 600 volts of capacity, they can usually be connected directly to an AC power source. However, certain conditions may suggest that a line reactor or isolation transformer should be placed between the drive and the power source for improved safety.
Unbalanced Distribution Systems
This drive has been specially designed for three-phase power systems, which are characterized by even voltage levels. Its protective function aims to reduce the risk of dangerous voltage fluctuations induced by lightning strikes or ground potentials between phases and the earth that surpass 125% of their typical values. Whenever there is a danger of this happening, as well as when the electrical ground connects with other pieces of equipment or other power systems, additional isolation procedures are required; using an isolation transformer is highly suggested in such cases.
Ungrounded Distribution Systems
Each of the 1336 PLUS drives has an integrated Metal Oxide Varistor (MOV) for additional security against sudden voltage surges and to conform with IEEE 587 for safeguarding against phase-to-phase and ground problems. However, it is essential to remember that MOV is only suitable for countering transient voltage spikes and not prolonged periods of operation. Additionally, if the distribution system is without proper grounding, the MOV's phase-to-ground attachment could create an irreversible current pathway toward the ground.
Digital I/Os
Terminal Block 3 (TB3) is where digital inputs can be found. Programming the appropriate control scheme, such as two-wire, three-wire, or status, allows various combinations to be achieved. Programing TB3 term 22 Sel through TB3 term 28 Sel completes setting up the remaining inputs. Digital outputs, meanwhile, are available at terminals 10 to 18 of TB2. Relays here will either become energized or de-energized depending on what function is programmed – powering up fault or alarm occurrences. For A-Frame drives, it is essential to install transient voltage surge suppression with a maximum clamping voltage of 2.5 kV onto the power supply used for relay contact outputs to safeguard it.
Encoder Inputs
Line driver-type encoders must be used, as they can generate either quadrature (two channels) or pulse (one channel) signals with either 5VDC or 8-15VDC. Single-ended or differential versions are available and should be able to supply a minimum of 10mA per channel at a maximum frequency of 250 kHz. Encoder inputs are located on terminal block 3 (TB3). The interface board can be configured for a 5V TTL signal, requiring at least 3.0V DC input, or a 12V DC square wave signal with a 7.0V DC minimum but not exceeding 18.5V DC as this may damage the board; the maximum low state voltage is 0.4V DC.
Pulse I/O
To properly utilize the 1336 PLUS drive component, the pulse input must be an externally powered 5V TTL square-wave signal. It must produce a voltage between 3.6 and 5.5V DC at 8 mA when in its high state and 0.0 to 0.8V DC in its common form, with a maximum input frequency of 250kHz. The scale factor [Pulse/Enc Scale] must also be adjusted. Exceeding the ±12V DC threshold can lead to signal degradation or, worse – component damage – so caution is advised here. On the output side, a TTL pulse train can drive up to three 1336 PLUS II pulse inputs, or a separate 125-ohm load at TTL levels (4 V source at 32 mA; 0.8 V sink at 3.2 mA) is available for use.
Analog I/O
The 1336 PLUS analog I/O setup features a core set of inputs and outputs, with room to add two extra option boards in their dedicated slots. When the option board is inserted in slot A or B, the connection terminals on TB2 will also be affected. As each slot can only fit one option board, careful consideration should be taken when selecting which ones to use.
Standard Analog I/O Setup
When no analog options are available for the 1336 PLUS II model, jumpers at the J9 and J10 connectors will be required to activate the I/O ports at TB2. Each jumper has four pins that must be connected in sets of 1-2, 3-4, 5-6, and 7-8, respectively. It is also possible to customize the input by adjusting the corresponding jumpers at connector points J8, J11, and J13; one on top for 0-10V operation, the bottom for 0-20mA, and the right side for potentiometer configuration. Nevertheless, all inputs are preprogrammed with a 0-10V default setting, and please note that ports 0, 1, and 2 aren'taren't positioned logically on the board.
Common Mode Cores
Common mode cores provide an effective method for decreasing common mode noise present at the drive output. They also protect against electromagnetic interference from sensors, analog circuits, and programmable controllers. Reducing the pulse-width modulation carrier frequency helps decrease the risk of interference from common mode noise.
Optional Outout Reactor
The Bulletin 1321 Reactors listed on the 1336 PLUS-3.0 Price Sheet have been designed explicitly for IGBT inverter applications and boast an impressive switching frequency of up to 20 kHz. They have a UL approval rating with a dielectric strength of 4000V, much higher than the regular 2500V standard. Additionally, these reactors feature triple insulation on both their first and last two turns, which are utilized to protect from insulation breakdowns that high DV/DT occurrences could cause. When opting for motor line reactors, it is best practice to lower the drive PWM frequency as low as possible in order to reduce losses across the reactors. However, if an output reactor is implemented, there will likely be a decrease in torque due to a voltage drop within the reactor.
Auxiliary Output - TB9
Drives with a size “F” frame have an output terminal block to provide a high-voltage, three-phase connection from the AC input line fuses on the load side. The voltage ranges between 480V and 600V depending on the input power supplied to the drive. Typically, this component is utilized to operate external control transformers or other supplementary circuits provided by users. Note that additional fusing might be needed if specific equipment is connected to TB9.
Human Interface Module
Providing a "snap-in" HIM to drive results in the latter being connected as Adapter 1, and it will be seen from the front. Not taking out this type of HIM is essential when the power supply is still running. The handheld HIM, on the contrary, can be connected with a 1202-Cxx Option Cable as an Adapter 2, 3, 4, or 5 even when electricity is present.
This kind of HIM has two divisions – the Display Panel, which helps program and view operating details, and the Control Panel, which aids in regulating drive functions. When an IP20-rated NEMA Type 1 enclosure without mounted "snap-in" HIMs is employed, make sure to fix up a blank cover plate (HASB option) at the front lid to dodge possible injuries or damages due to careless behavior. And if the attached "snap-in" HIMs have been detached inadvertently, putting back the blank cover plate must be done immediately.
Not only is it worth mentioning that the operation of certain HIM features may rely on parameters that have been set, but the traditional values guarantee the full functionality of HIMs. After connecting power to the drive, its name, HIM ID number, and communication status will show in a sequence. This will be followed by Status Display indicating the current level or any existing faults. There are several modes one can access with an HIM, such as Display, Process, Program, StartUpP, EEProm, and Control Status, which provide varying levels of accessibility for functions and parameters.
Furthermore, some HIMs allow one to exchange parameter information between itself and the drive; additionally, there's a Password mode designed to protect from unintended changes in programming via requesting a correct password for entering special menus and modes.
Startup mode simplifies the process of starting up the drive by leading the user through its essential steps. EEPROM mode can reset all parameters to their original factory settings. Moreover, some HIMs can upload and download data between them and the drive.
The Control Status mode permits enabling/disabling the drive logic mask when needed, such as when a handheld HIM has been removed while power is still applied. This mode additionally grants access to a fault queue displaying four recent faults causing the shutdown, among which ''Trip'' refers to any shutdown-triggering error code.
To prevent changes from being made to the drive's parameters without authorization, Password mode employs passwords ranging between 00000 and 65535 digits long as verification when entering specific menus and modes like Program/EEProm and Control Logic/Clear Fault Queue.
