Allen-Bradley 22C-D142A103

The Allen-Bradley 22C-D105A103 is a performant, feature-rich adjustable frequency AC drive suitable for various fan and pump applications in industrial environments. Its robust design makes it ideal for motors with long working hours. The comprehensive protection features and flexible configuration options make it a reliable choice for many applications.

Technical specifications:

This AC drive is part of 380-480V AC, Three Phase Drives series and has a power rating of 55 kW (75 HP) with an output current of 142A. Its operating frequency ranges from 48 to 63Hz and has a displacement power factor of 0.98 across the entire speed range. Under nominal conditions, it is 97.5% efficient at rated amps, making it ideal for versatile applications.

It uses an Isolated Gate Bipolar (IGBT) transistor. It comes with a panel mount, IP30, and NEMA/UL Type 1 enclosure, providing basic protection for indoor use. It can easily be mounted in the control cabinet where the air temperature is within “10..+45 °C range.

Key Features:

The many I/O features, making it very user-friendly of the Adjustable frequency AC drive makes it very user-friendly. It has three partially programmable and four completely programmable digital inputs that allow for flexible control configurations.

The AC drive has embedded protocols like Modbus RTU, and Metasys N2, which are parameter selectable. No additional hardware is required for integration and communication. It can support Drive Serial Interface communication modules for protocols like EtherNet/IP, PROFIBUS DP, and BACnet.

Protective features:

The Allen-Bradley 22C-D105A103 is one of the highly reliable drive series. It comes with several protective features that protect the connected motors and personnel. The ground fault protection feature is used to protect against ground faults during operation, which ensures smooth operations. Electronic motor overload protection increases motor life, and 6 kV transient protection provides increased robustness for 380-480V system voltage.

The 22C-D105A103 has a built-in PID control loop that keeps variables like flow and pressure at the desired set point using a feedback mechanism. The PID feedback is subtracted from the reference value to calculate the error. Based on the PID gains, the PID loop responds to the error and outputs a frequency to bring the error value down to zero. In this way, variables are kept at the desired value.

Programming and Communication:

The AC drive features a keypad and LCD for monitoring. The keypad includes Hand/Off/Auto function buttons, digital increase and decrease speed control, and system status LEDs. The parameters are organized in filesystems based on functionality, making programming robust. The parameter readings are displayed on the screen as plain text. The text can be displayed in English, Franais, Espa±ol, Italiano etc. Its functions ca easily be understood by layman.

Frequently Asked Questions:

How to configure the analog inputs on the Allen-Bradley 22C-D142A103 for different signal types?

To configure the analog inputs on the 22C-D142A103, you need to set the DIP switches to the desired value. The drive includes two analog inputs: Analog Input 1 and Analog Input 2. Each input can be set to accept either voltage or current signals.

How can the Allen-Bradley 22C-D142A103 be programmed with a PC?

The programming of 22C-D142A103 from a PC is possible with integrated RS-485 connections. It may also be utilized in a multidrop network architecture. A serial conversion module makes connectivity to any controller with a DF1 port possible.

What is the optimum temperature for 22C-D142A103 to work efficiently?

The optimum temperature for efficient working is up to 45°C without derating. The drive derates by 3% for every 305m for altitudes higher than 1000 m
