Allen Bradley 1336 IMPACT AC Inverter

Product Overview and Core Features

1. Product positioning and applicable scenarios

1336 IMPACT frequency converter is a microprocessor based field oriented control (FOC) AC frequency converter using Force technologies ™ Technology, focusing on low-cost independent applications, suitable for scenarios such as machine tools, production lines, and material handling that require precise speed regulation, supports speed and torque control of asynchronous motors, and is compatible with multiple feedback devices and communication protocols.

2. Core standard features

Performance and Control:

High precision digital speed loop and current loop, supporting 0-250Hz constant torque output, some configurations can achieve 400% motor current (short-term overload).

Supports multiple braking methods: dynamic braking, DC braking, magnetic flux braking, and bus voltage regulation, adapting to different load deceleration requirements.

Feedback and Interface:

Standard configuration includes 2 ± 10V analog inputs, 2 ± 10V analog outputs, and 1 4-20mA input/output. The 12 bit resolution ensures signal accuracy.

Support encoder feedback (requires L Option board), compatible with 12V/5V differential output encoder, up to 100kHz pulse input, achieving high-precision speed/position control.

Protection and reliability:

Built in motor overload protection (I ² T), inverter overload protection, overcurrent, overvoltage, undervoltage, ground fault, overheating and other multiple protections.

32 fault queues and 32 warning queues, with timestamps and fault markers for easy problem tracing; Non volatile memory (EE) stores parameters and configurations without loss during power outages.

Communication and Expansion:

Supports SCANPort communication and can connect to HIM (Human Interface Module), GPT (Graphics Programming Terminal), and 1203 series gateway modules (such as DeviceNet, RS-232/485).

Optional L Option board extension control input, supports TTL/24V AC/DC/115V AC interfaces, and some models come with encoder feedback interfaces.

Model Interpretation and Framework Classification

1. Model coding rules (taking 1336E-AQF05-AA-EN as an example)

Explanation of the meaning of digit codes

1-4 Position 1336E Product Series 1336 IMPACT AC Inverter

Position 5-6 AQ voltage level AQ=200-240VAC/310VDC; BR=380-480VAC/513-620VDC； CW=500-600VAC/775VDC

The rated power of F05 in positions 7-9 is 0.37kW (0.5HP); F07=0.56kW (0.75HP)； F10=0.75kW (1HP)， Repeat this process until 800C=597kW (800HP)

AA protection level AA=NEMA 1 (IP20) for positions 10-11; AE=NEMA 1 (IP20)/EMC (0.37-45kW dedicated); AF=NEMA 4 (IP65)； AJ=NEMA 12 (IP54)

The 12th and 13th digits of EN language are English/English; FR=English/French; ES=English/Spanish; DE=English/German, etc

Subsequent mod options include HIM type (such as HA1 with analog potentiometer), communication module (such as GM5=DeviceNet), and L Option board (such as L8E=24V AC/DC+encoder)

2. Frame classification and power correspondence

The framework is divided by size and power, and the installation and wiring requirements for different frameworks are different. The core correspondence is as follows:

Framework Model 200-240V Power Range 380-480V Power Range 500-600V Power Range Key Features

A1 0.37-0.75kW (0.5-1HP) 0.37-1.2kW (0.5-1.5HP) - miniaturization, suitable for light loads

A2 1.2-1.5kW (1.5-2HP) 1.5-2.2kW (2-3HP) - Compact, supporting basic analog control

A3 2.2-3.7kW (3-5HP) 3.7kW (5HP) - Medium load, optional encoder feedback

A4-5.5-7.5kW (7.5-10HP) 0.75-7.5kW (1-10HP) with cooling fan, supporting dynamic braking

B 5.5-11kW (7.5-15HP) 15-22kW (20-30HP) 11-15kW (15-20HP) modular design, supporting multiple communication interfaces

C-H 30-75kW (40-100HP) 45-597kW (60-800HP) high power, requiring external reactors, H frame with independent cooling system

Installation and wiring specifications

1. General safety requirements

Static protection: The module contains ESD sensitive components, and a grounding wristband should be worn during operation. Refer to Rockwell document 8000-4.5.2 "Guidelines for Preventing Static Damage".

Power off operation: Before installation, all power sources of the frequency converter (including AC input, DC bus, control power) must be disconnected to avoid electric shock or component damage.

Cable requirements: Power cables must comply with NEC/VDE standards, and it is recommended to use shielded twisted pair cables (such as Belden 8760) for control cables to avoid parallel laying with high-power cables and reduce interference.

2. Key points for exclusive installation of the framework

(1) A1-A4 frame (low power)

Rail installation: Suitable for 35 × 7.5mm DIN rails, with hooks inserted and locked by rotation. The grounding resistance should be ≤ 2 Ω (detected through the metal shell of the RS-232 port).

Wiring terminal: TB1 is the power terminal (R/L1, S/L2, T/L3 input; U/T1, V/T2, W/T3 outputs), TB4/TB7/TB10 are control terminals, supporting analog I/O, pulse input, and relay output.

Input protection: Users need to provide their own fuses. For example, models with 200-240V/0.37kW require 6A Class CC fuses (North America) or 6A gG fuses (Europe).
