REOTRON 567LH-DP24 Fully Adjustable Torque & Speed Control Module with Potentiometer Interface

Description

Application Scenarios

In an automotive parts assembly line in Michigan, a series of small conveyor segments used aging brushed DC motors that frequently stalled under variable loads, causing production jams. Engineers replaced the obsolete controllers with REOTRON 567LH-DP24 units, leveraging their built-in current limiting and adjustable acceleration/deceleration features. The regenerative braking function allowed smooth, controlled stops—even when back-driven by heavy fixtures—eliminating mechanical brake wear. Additionally, the drive’s tachometer feedback input (optional) enabled closed-loop speed regulation within ±1% despite voltage sags during peak plant demand. Within three months, unplanned downtime dropped by 40%, demonstrating how the REOTRON 567LH-DP24 transforms basic DC motors into intelligent, responsive motion subsystems.

Technical Principles and Innovative Values

Innovation Point 1: True Regenerative Braking at Low Voltage

Unlike simple dissipative (rheostatic) brakes, the 567LH-DP24 actively returns kinetic energy to the DC bus during deceleration—improving energy efficiency and enabling rapid, controlled stops without external resistors.

Innovation Point 2: Dual-Mode Control Flexibility

Users can operate in open-loop (voltage command) or closed-loop (with tach feedback) mode using the same hardware. The tach input compensates for load-induced speed droop, achieving near-servo performance from a cost-effective DC motor.

Innovation Point 3: Integrated Protection Without External Components

Built-in thermal monitoring, current foldback, and soft-start eliminate the need for external fuses or contactors in many applications—reducing panel space and wiring complexity.

Innovation Point 4: German-Engineered Ruggedness for Industrial Environments

Designed and tested to REO’s stringent EMC and thermal standards, the 567LH-DP24 withstands electrical noise from nearby VFDs, welders, and solenoids—common in factory settings.

Application Cases and Industry Value

A European medical device manufacturer integrated the REOTRON 567LH-DP24 into a blood sample analyzer requiring ultra-smooth motion for carousel positioning. The drive’s low-speed stability (< 50 RPM without cogging) and quiet operation met strict acoustic requirements. In another case, a solar tracker test rig in Arizona used multiple 567LH-DP24 units to simulate motor loads under extreme ambient temperatures. The drives operated reliably at 48°C ambient with no derating issues, thanks to efficient heat dissipation through the aluminum baseplate.

Installation, Maintenance, and Full-Cycle Support

Installation of the REOTRON 567LH-DP24 requires secure DIN-rail mounting with adequate ventilation (min. 20 mm clearance on sides). Wiring should use shielded cable for speed reference and tach signals, with shields grounded at the drive end only. Motor leads must be twisted pair to reduce EMI.

Key setup steps include:

Set max speed and current limit via internal potentiometers.

Configure acceleration/deceleration time using onboard trimpots.

If using tach feedback, calibrate gain to match motor tach constant (e.g., 5 V/1000 RPM).

Maintenance is virtually zero—no fans, brushes, or consumables. However, periodic inspection of terminal tightness and dust accumulation is advised in harsh environments. The drive’s status LED indicates normal operation (green) or fault (red), with blink codes for diagnostics (e.g., overtemp = 2 blinks).
