A-B 1336-BDB-SP79D Rockwell Automation 1336 Series High-Power Inverter Dedicated Gate Drive Board

Product Brief Description

The 1336-BDB-SP79D is a high-reliability high-power gate drive board independently developed by Rockwell Automation (Allen-Bradley), belonging to the classic Allen-Bradley 1336 series adjustable frequency AC drive core supporting product line. As the key IGBT power drive component specially designed for high-power industrial frequency converters, it is widely deployed in heavy-duty industrial scenarios such as metallurgy, petroleum, chemical industry, electric power, large-scale machine tool equipment and other industries that have extremely strict requirements for high-power motor drive reliability, responsible for accurately controlling the on-off action of the high-power IGBT power devices inside the frequency converter, converting the weak control signal output by the main control board into a high-power drive signal that can directly drive the IGBT, ensuring that the large-capacity motor can accurately and stably perform speed regulation and torque control during long-cycle uninterrupted operation, providing the most fundamental power drive guarantee for the stable operation of large-scale industrial production equipment.

Key Core Functions

• High-Precision IGBT Drive Control: As the core power drive component of the frequency converter, the module can accurately amplify the weak control signal output by the main control board into a high-stability gate drive signal that can directly control the high-power IGBT, ensuring that the IGBT can be turned on and off quickly and accurately, so that the high-power motor can obtain precise speed regulation and torque control performance, and the speed control accuracy can reach within ±0.1%
• Full-Cycle Motor Operation Protection: The module continuously monitors the operating current, voltage and temperature of the IGBT and the motor in real time during the operation process. Once abnormal conditions such as motor overload, overcurrent, overvoltage, overheating and short circuit are detected, it can immediately trigger the protection action, quickly cut off the drive signal, avoid the damage of the IGBT power device and the motor, and effectively extend the service life of the high-power frequency converter and the motor
• Excellent System Compatibility: The module has perfect compatibility with all sub-series products of Allen-Bradley 1336 series frequency converters including 1336 PLUS, 1336 FORCE, 1336 IMPACT and 1336 PLUS II, and can be directly used as a spare part for the maintenance and replacement of old 1336 series high-power frequency converters that have been in operation for many years, without additional complex adaptation and modification
• Industrial Grade Strong Environmental Adaptability: The whole board adopts industrial grade components that are resistant to high and low temperature, anti-strong electromagnetic interference, anti-vibration, which can stably work in the harsh industrial environment of the workshop, and effectively resist various power quality fluctuations and electromagnetic interference in the industrial site, and will not cause drive signal distortion and misoperation due to the complex on-site environment
• Easy Maintenance and Replacement: The module is designed with standardized installation dimensions and dedicated jumper connectors with clear marks, which can effectively eliminate wiring errors. Maintenance personnel can quickly complete the disassembly and replacement operation of the drive board without modifying a large number of internal wiring of the frequency converter, which greatly shortens the system fault recovery time and reduces the production loss caused by equipment shutdown

Typical Application Scenarios

• Metallurgy industry: Large rolling mill main drive motor frequency converter system, realizing high-precision speed regulation control of the rolling mill motor
• Petrochemical industry: Large oil pipeline transmission pump and compressor drive frequency converter system, ensuring the stable operation of the fluid transportation equipment
• Electric power industry: Large power plant boiler induced draft fan, forced draft fan and circulating water pump frequency converter speed regulation system, realizing energy-saving operation of auxiliary equipment
• Machine tool manufacturing industry: Large heavy-duty CNC machine tool spindle drive frequency converter system, realizing high-torque and high-precision spindle motion control
• Industrial transformation and upgrading projects: Spare parts replacement and system maintenance of old Allen-Bradley 1336 series high-power frequency converter systems that have been in operation for many years in various industrial sites

Installation and Maintenance Guidelines

• Strict anti-static protection must be implemented before installation: operators must wear a reliably grounded anti-static wrist strap and anti-static gloves to avoid static electricity damaging the precision IGBT drive chips and power components on the board
• Before disassembly and maintenance, it is necessary to confirm that the DC bus voltage inside the frequency converter has been completely discharged to zero, to avoid the risk of electric shock caused by the residual high voltage on the power device
• After installation, perform full function test of the frequency converter system through the dedicated Rockwell frequency converter debugging software, confirm that the IGBT drive function, protection function and motor speed regulation performance of the drive board fully meet the design requirements
• Regularly check the operation status indicator on the drive board during daily operation, regularly clean the dust accumulated on the surface of the circuit board every 1-2 years, and check the aging of the cooling fan, which can effectively extend the service life of this gate drive board to more than 10 years
