Allen Bradley 1336 PLUS II Adjustable Frequency Driver

Allen Bradley 1336 PLUS II Adjustable Frequency Driver

Product Core Overview

1. Basic positioning and applicable scenarios

Function positioning: Based on microprocessor, PWM AC driver is used to control the speed of three-phase motors. It adapts to various load requirements through adjustable voltage/frequency (V/Hz) or sensorless vector control, especially suitable for industrial scenarios with high requirements for torque and speed accuracy (such as fans, pumps, conveyors, etc.).

Power and voltage range: The power covers 0.37-448kW (0.5-600 horsepower) and supports three voltage levels -200-240V AC, 380-480V AC, and 500-600V AC, which can meet industrial power supply standards in different regions.

Compatibility advantage: with Allen Bradley SMC ™、 SMP ™ Power products, 1305 drivers, 1336 IMPACT ™ And 1336 FORCE ™ Vector control drivers share control interfaces and communication options to reduce system design, integration, and maintenance costs.

2. Core design highlights

Structural design: Flat construction reduces internal cables and connectors, improving reliability; Laminar busbar design reduces internal inductance, minimizes buffering losses, and optimizes IGBT performance; Removable Human Machine Interface (HIM) simplifies programming and operation.

Heat dissipation and protection: optimize thermal management through infrared testing to reduce hotspots; Supports IP20 (NEMA Type 1, Universal), IP54 (NEMA Type 12, Dustproof), IP65 (NEMA Type 4, Waterproof and Dustproof) protection levels, suitable for different industrial environments.

Global adaptation: Compliant with international standards such as UL, CSA, EN, IEC, VDE, etc., equipped with DC cooling fans, no need for transformers and voltage taps, supporting global use.

2. Environment and operating specifications

Environmental conditions: Maximum altitude of 1000m (without capacity reduction), exceeding this limit requires reference to the capacity reduction guidelines; The working temperature IP00 (open type) is 0-50 ℃, and IP20/54/65 is 0-40 ℃; Storage temperature -40-70 ℃; Relative humidity 5-95% (no condensation), shock resistance 15G peak (11ms), vibration resistance 0.006 inches displacement (1G peak).

Output performance: Output frequency range 0-400Hz, frequency accuracy (digital input) ± 0.01% set value, (analog input) ± 0.4% maximum value; Acceleration/deceleration time can be independently programmed (0-3600 seconds, 0.1 second increments); The overload capacity of constant torque load for 1 minute is 150% of the rated output, and the overload capacity of variable torque load for 1 minute is 115% of the rated output.

Core functional characteristics

1. Motor control function

Sensorless vector control: Excellent torque performance at low speeds (as low as 15rpm), with a constant torque speed range of 120:1 and a starting/accelerating torque of up to 250%. It supports motor parameter self-tuning (requires input of motor nameplate values) and is suitable for fast acceleration requirements of low inertia loads.

V/Hz control: fully programmable mode, supporting startup lifting, operation lifting, and slope adjustment for lifting, suitable for multi motor co drive scenarios (such as different power motors sharing one driver).

Slip compensation: Automatically increase the output frequency according to the load, compensate for the rotor slip of the induction motor, with a typical speed adjustment accuracy of 0.5%, to avoid speed drop caused by increased load.

Flying Start function: It can detect the speed and direction of the rotating motor without the need for an encoder, start from the current speed and transition to the commanded speed, and adapt to scenarios such as fans and pumps that require "load start".

2. Process control and protection

Process PI controller: Through proportional (KP) and integral (KI) gain adjustment, combined with feedback scaling, error reversal, and output clamping, it achieves speed closed-loop control based on feedback signals (such as pressure and flow), supporting "automatic/manual" switching and smooth transition.

Braking function: Supports DC injection braking (programming time 0-90 seconds), dynamic braking (requires an external braking unit), and continuous holding braking (sets the "Ramp to Hold" mode, outputs the set current at zero frequency until the start command or enable is disconnected).
