REXROTH TVD1.2-15-03 | Indramat TVD1.2 Frequency Inverter Drive 3 kW 400 V

Description

Product Introduction

The REXROTH TVD1.2-15-03 is a member of the Indramat TVD1.2 series of frequency inverters. It is engineered to control the speed and torque of three-phase AC motors, making it a staple in industrial automation setups where precise motion control is required.This drive unit is rated for 3 kW output power and handles an input current of 15 A. It operates within a wide voltage range of 380 to 480 VAC, providing flexibility in various power environments. The drive supports a frequency output range of 0 to 400 Hz, allowing for high-speed operation of connected motors. It features robust construction typical of Bosch Rexroth industrial electronics, designed for reliability in demanding operating conditions.

Application Scenarios & Pain Points

On-Site Failure Scenario
Imagine a packaging line in a food and beverage plant grinding to a halt because the conveyor motor is running uncontrollably fast. The old drive has failed, and the production manager is losing thousands per minute. This is where the REXROTH TVD1.2-15-03 earns its keep. As a direct replacement for the Indramat TVD1.2 series, it slots right back into the rack, restoring the precise speed regulation needed to keep bottles moving smoothly under the capping machine without a hiccup.Key Applications

• Material Handling: In warehouses, these drives control the speed of sorting conveyors, ensuring packages don’t collide or get stuck in merges.
• Pump & Fan Control: In HVAC systems, the TVD1.2 adjusts motor speed based on demand, cutting energy costs significantly compared to fixed-speed operation.
• Machine Tools: On CNC lathes, the wide 0–400 Hz frequency range allows the spindle to ramp up to high RPMs for fine finishing cuts, a capability not all standard drives offer.
• Textile Industry: Maintaining constant tension on yarn spools requires the torque stability this drive provides, preventing thread breakage during high-speed weaving.

Case Study: Retrofitting an Aging Press
A metal fabrication shop in Ohio was struggling with frequent downtime on a 20-year-old hydraulic press. The original Indramat drive was overheating and shutting down.

• The Problem: The cooling fins were clogged, and the internal fan was failing. Finding an exact “new” old stock unit was proving impossible.
• The Solution: They sourced a REXROTH TVD1.2-15-03 (which is the modern nomenclature for the same hardware).
• The Outcome: After a quick swap and parameter copy, the press was back online. The shop manager noted that the newer unit ran 10°C cooler under the same load, extending the lifespan of the surrounding electronics.
