Frequently Asked Questions
Q1: What are the main features of the RM-NPLA Micro Platform-type Linear Actuator?
RM-NPLA Micro Platform-type Linear Actuator features a compact design well-suited for factory automation. It offers multiple stroke and force options, enabling flexible configuration for different load and process requirements. With high positioning repeatability and stable high-speed performance, the RM-NPLA supports a wide range of applications across 3C electronics, precision manufacturing, and automotive assembly.
Q2: What is the difference between the ITG Model and the Split Type Model?
ITG model (Integrated): built-in controller within the actuator body.
Split Type Model: actuator with an external controller; a compatible controller must be selected when ordering.
Q3: How to select the right controller for the RM-NPLA Micro Platform-type Linear Actuator?
For the specific compatible controller, please refer to the technical specifications of the series. Confirmation of the required communication protocol will determine the exact controller model.
Q4: Does the RM-NPLA Micro Platform-type Linear Actuator support power-off mechanical self-lock?
No. RM-NPLA is not equipped with a mechanical self-locking mechanism. If your application requires a braking function, please contact RobustMotion or an authorized RobustMotion distributor in your region.
Q5: Besides Modbus RTU, what communication protocols are supported?
The standard communication protocols supplied for overseas markets include I/O control, Modbus RTU, Modbus TCP, and EtherCAT. For the latest information, please contact RobustMotion or an official RobustMotion distributor in your region.
Q6: Can the control software for RM electric actuators be downloaded from the RobustMotion website?
Yes. Except for the RM-EGB series, all RM electric actuators should be connected using RM Software (V6 version).
Q7: What are the industrial applications of the RM-NPLA Micro Platform-type Linear Actuator?
RM-NPLA Micro Platform-type Linear Actuator is widely used in precision linear motion tasks across multiple industries, including:
- 3C Electronics – Coil PIN alignment for in-car audio systems
- 3C Electronics – Motor assembly
- Precision Manufacturing – High-thrust lifting of carbide fixed-handle drills
- Precision Manufacturing – Triangle radar inspection for robotic vacuum cleaners
- Automotive Assembly – Insertion of automotive fuses
Q8: What is the maintenance procedure for the RM-NPLA Micro Platform-type Linear Actuator?
Please refer to the Maintenance section in the RM-NPLA User Manual.
Q9: What are the benefits of electric actuators compared to pneumatic actuators?
Compared to pneumatic or hydraulic systems, electric actuators offer higher efficiency, cleaner operation, and superior motion accuracy. They provide high precision, repeatability, and programmable control, allowing real-time adjustment of speed, position, and force. With energy-saving operation, lower maintenance, and easy integration with digital control systems, electric actuators are widely used in industrial automation, robotics, intelligent manufacturing, and precision handling applications.
