Controlling multiple linear actuators in perfect synchronization is essential for many automation systems — from precision testing platforms to coordinated robotic movements. But managing multiple actuators simultaneously doesn’t has to mean adding system complexity. With our MMB actuators and dedicated MMA Actuator Controller, you can control multiple linear actuators using a master-slave setup — enabling coordinated, real-time motion with minimal wiring and configuration.
One Controller, Multiple Actuators
Our Linear Actuator Controller has built-in functionality to enable the movement synchronisation of multiple actuators simultaneously. It works by configuring one MMA controller (the master) to generate a motion profile — such as a sinusoidal waveform — which is shared with other MMA controllers (the slaves) via an analog output. The slave controllers receive the master signal via their analog input and replicate the exact movement in real time .
This means all actuators move in sync, whether you’re controlling two or ten. This is ideal for multi-axis systems, clamping mechanisms, or synchronized displacement across a surface or fixture. The same synchronous operation can also be achieved by configuring multiple MMA controllers to Analog input control in either Position/Force/Current mode and supplying them all with the same external Analog signal from a third party controller
How Does It Work?
Here’s how synchronized control is typically set up:
- Master MMA Linear Actuator Controller
The master actuator is connected to our master MM Controller, which is programmed to define the desired motion (e.g., waveform shape, stroke, frequency). - Analog Output
The MMA Controller outputs this signal through its DAC (digital-to-analog converter) port. - Slave MMA Linear Actuator Controllers
Other actuators — the slaves — are connected to separate slave MMA Controllers. These are configured to follow the analog input signal from the master. - Synchronized Motion
Once connected, all actuators follow the same profile, ensuring coordinated linear motion with high accuracy.
Even better: you can update the waveform parameters live, without interrupting the system. This flexibility is ideal for adaptive automation or on-the-fly calibration.
Do I Need External Encoders for Position Feedback?
No — and this is one of the major advantages of our system. The Electric Linear Actuator Controller supports sensorless position control, using internal coil sensing to estimate position. This reduces:
- The number of components
- System complexity
- Wiring and integration time
