ABB 1TGE120071R1000 High-Power AC Variable Frequency Drive (VFD)

Description

1TGE120071R1000

The ABB 1TGE120071R1000 functions as a sensorless vector control VFD designed for mid-sized industrial motors, converting 3-phase AC input into variable output to adjust speed (0 Hz–500 Hz) and torque based on process demands. Unlike lower-power VFDs that struggle with high-inertia loads, this model handles 15 kW motors with ease, delivering a rated current of 32 A (at 400V, 50Hz) to support continuous heavy-duty operation.

It retains core VFD capabilities—soft-start to reduce inrush current, variable speed control to cut energy use, and comprehensive protection (overcurrent, overvoltage, undervoltage, thermal overload, and short-circuit)—but adds features tailored to mid-sized applications: a built-in braking chopper (for rapid deceleration of high-inertia loads like large fans) and expandable I/O (via optional modules) to integrate with external sensors or control systems. The VFD supports industrial protocols like Modbus RTU and optional PROFINET, enabling seamless communication with PLCs (e.g., ABB AC500, Siemens S7-1500) or SCADA systems for remote monitoring and control. By mounting onto a standard 35mm DIN rail or via panel brackets, it fits into industrial control cabinets while providing easy access to terminals and a backlit keypad for local configuration. In the automation stack, the ABB 1TGE120071R1000 acts as a bridge between the power supply and mid-sized motors: it receives real-time commands from the control layer, adjusts motor output to match load demands, and feeds back operational data (current, temperature, fault codes) to ensure alignment with system goals—all without compromising performance.

Main features and advantages:

Choosing the ABB 1TGE120071R1000 delivers tangible value that enhances mid-sized motor performance, reduces energy costs, and simplifies heavy-duty system integration. Engineered for high-power reliability, its robust design handles continuous operation of 15 kW motors—eliminating overload faults that plague undersized drives and cutting unplanned downtime by 40% in high-demand applications. The built-in braking chopper enables rapid deceleration of high-inertia loads (e.g., large centrifugal pumps), preventing mechanical stress on motor components and extending equipment life by 30% compared to drives without braking capabilities. For engineers, the expandable I/O and protocol support reduce integration complexity: optional PROFINET modules enable seamless connectivity with Siemens-based automation systems, while Modbus RTU ensures compatibility with legacy control panels—avoiding the need for costly system overhauls.

Additionally, the ABB 1TGE120071R1000 retains ABB’s signature energy efficiency, cutting consumption by 25–55% in variable-demand applications. For example, a 15 kW industrial fan running at 70% speed uses only 34% of the energy required at full speed, translating to $5,000+ in annual savings for 24/7 operations. Unlike generic high-power VFDs that lack precision, its sensorless vector control maintains torque accuracy within ±5%—critical for applications like extruders or mixers that require consistent output. The drive’s compliance with IEC 61800-5-1 and UL standards also ensures safety and interoperability, reducing the risk of compliance violations in regulated industries (e.g., oil and gas, pharmaceuticals).

Application fields:

The ABB 1TGE120071R1000 excels in industries where mid-sized motor control and heavy-duty performance are mission-critical. In wastewater treatment, it controls 15 kW submersible pumps: variable speed adjustment matches pump output to water levels, preventing over-pumping and reducing wear on pump impellers. In manufacturing, it powers large conveyor motors in automotive component plants: the built-in braking chopper ensures quick stops during emergency shutdowns, protecting workers and preventing product damage. In chemical processing, it regulates 15 kW fan motors for fume extraction: sensorless vector control maintains consistent airflow even as filter resistance increases, ensuring compliance with air quality standards. Across all these use cases, the drive’s high-power capacity and robust features make it a trusted solution for heavy-duty industrial applications.

Installation and maintenance:

Before installing the ABB 1TGE120071R1000, confirm the motor’s rated power (max 15 kW) and voltage (380V–480V, 3-phase) to avoid overload. Ensure the control cabinet has adequate space (account for 220mm width and 50mm clearance on all sides) for airflow—derate the drive by 10% for each 5°C above 50°C. Use heavy-gauge wiring (min 6mm² / 10AWG) for motor connections to handle 32A current, and shielded cables to reduce EMI. For braking applications, install a compatible braking resistor (per ABB’s specifications) to avoid overvoltage faults during deceleration. If using PROFINET, verify the PLC’s protocol support and assign an IP address via DCP (Discovery and Basic Configuration Protocol) to avoid manual errors. For ongoing maintenance, inspect cooling fans monthly for dust buildup—clean with compressed air to prevent overheating. Check input/output terminals quarterly for tightness and corrosion, and update firmware via ABB’s DriveComposer software to access new features. If a fault occurs, use the drive’s display to view error codes (e.g., “OC” for overcurrent) and refer to the manual for targeted troubleshooting.
