ROGER TECHNOLOGY MASTER-SLAVE TECHNOLOGY

f you’re here, the answer is probably yes—and that’s exactly what Master-Slave technology is all about.

This feature, developed for Roger Technology motors, automatically coordinates two or more Brushless motors, transforming them into a single system that operates as one automation.

During installation, you’ll benefit from fewer adjustments, greater reliability, and a system that maintains smooth, precise, and consistent movement over time. The result is a gate that opens and closes with outstanding fluidity, accuracy, and continuity—day after day—even when using two motors with different characteristics.

In this article, we’ll take a closer look at how this technology works, the advantages it offers, and the installation scenarios where it truly makes a difference.

Why Synchronization Has Become an Essential Requirement

Gate automation has evolved dramatically over the past few years. While the primary objective was once simply to automate manual gate operation, today’s market demands much more.

Users expect systems that are fast, quiet, reliable, and capable of maintaining consistent performance even after thousands of operating cycles. At the same time, the work of installers like you has become increasingly complex.

Every installation presents its own unique challenges:

• Large gates
• Opposing openings
• Intensive use
• Limited installation space
• Increasingly demanding aesthetic requirements

In these situations, using two independent automation systems means dealing with a number of issues that experienced professionals know all too well.

Even when high-quality products are used, two motors operating independently can gradually develop slight differences in behaviour.

We’re talking about almost imperceptible variations, such as:

• A slight difference in speed
• One motor accelerating slightly earlier
• Deceleration that isn’t perfectly synchronized
• Stopping fractions of a second apart

Over thousands of opening and closing cycles, however, these small discrepancies can affect the perceived quality of the installation, increase maintenance adjustments, and compromise the smoothness of the overall movement.

To address this real-world need, Roger Technology developed its Master-Slave technology with the ambitious goal of making two motors operate as if they were one intelligent automation system.

What is roger technology master-slave technology?

Master-Slave technology is an integrated feature available on Roger Technology Brushless automation systems, specifically designed for installations where two motors must operate in perfect synchronization.

One motor is assigned the role of Master, while the other is configured as the Slave.

From that moment onward, the system no longer functions as two independent automation units, but behaves as a single automation system.

Every command—whether it comes from a remote control, key selector, access control system, home automation system, or any other control device—is received exclusively by the Master motor, while the Slave motor automatically processes the commands in complete coordination.

The simultaneous opening of the gates ensures perfectly harmonious movement from the very first moment, while synchronized acceleration management eliminates behavioural differences between the two motors.

This approach removes most of the discrepancies that would normally occur between two separate automation systems.

Let’s now look at the available configuration options.

🔥 With the B70/1DC and B70/1DCHP control units for Digital Brushless sliding gates, you can activate the Master-Slave function even between two different control boards—and even between motors from different product series, provided they use the same control unit.

📦 BH30 + BM30 = YES, IT’S POSSIBLE!

📦 BG30/1604 + BG30/804/HS = YES, IT’S POSSIBLE!

🎯 Here are three typical installation scenarios.

🔹 EASY

Identical Motors (90% of Installations)

💡 Imagine you’re automating a large industrial sliding gate where two BG30/804/HS motors are required to deliver the necessary power and perfect symmetry.

✅ Same series, same model, complete synchronization.

🔹 PRO

Same Series, Different Models

💡 For example, two sliding gate leaves of different lengths in a residential property, using a BH30/604/HS on one side and a BH30/804 on the other to balance the mechanical load.

✅ Same product series, but different motors selected to suit the installation requirements.

🔹 MASTER

Different Series, Different Models

💡 You’re carrying out a partial upgrade on an existing installation where the customer wants to keep an older BG30 motor already installed while adding a new BM30 motor to automate a second sliding entrance.

✅ Different product series—with different control boards—that can still communicate using Master-Slave technology.

🧠 And don’t forget: you can adjust forces, speeds, safety settings, and connect safety edges wherever it’s most convenient—often directly to the SLAVE control unit.
