The 80AST-A1C02430 servo motor should be powered by a 220V AC nominal voltage. At 750W power and 220V AC supply, it will draw a nominal current of approximately 3.4 Amperes (750W / 220V). Considering driver losses and system inefficiencies, it is recommended to leave some margin when selecting your power supply unit.

The motor is designed to continuously provide a rated torque of 2.4 N·m at a rated speed of 3000 RPM. These values represent the ideal performance points under nominal operating conditions, where the motor produces its specified 750W power and ensures long-term operation.

6000 RPM is the maximum speed the motor can reach. Continuous operation at this speed may shorten the motor’s lifespan or cause overheating. The motor’s rated speed is 3000 RPM, and continuous, efficient operation at this speed is recommended. 6000 RPM should generally be considered a peak value for short-term acceleration or precise positioning operations.

Yes, the main advantage of the 17-bit absolute encoder is that it precisely retains the motor’s current position information even during power interruptions. When the system is powered back on, there is no need for the motor to move to a reference point (homing) to find its initial position, which reduces machine startup times and increases production efficiency.

The T3D-L20A-RABF driver supports both +5V and +24V signal voltages. You should choose based on your PLC’s output signal voltage. Typically, industrial PLCs provide +24V output, making it a common choice. It is important to check your PLC’s technical documentation and set the correct signal level before making the connection.

The 10-meter power and encoder cables provided by Mermak CNC are selected to maintain signal integrity and minimize losses under the set’s nominal operating conditions. Generally, additional measures are not required for distances up to 10 meters. However, if operating in an industrial environment with high electromagnetic interference, separating the cables from other power lines or using shielded cable conduits can further enhance performance.

The IP65 protection class indicates that the motor is completely dust-tight (first digit 6) and protected against low-pressure water jets from any direction (second digit 5). This allows it to be safely used in dusty manufacturing environments and applications where it may be exposed to light water splashes. However, it is not resistant to immersion in water or high-pressure water jets.

Yes, this set is designed for position control in applications requiring high precision, such as industrial robots, engraving machines, and automation equipment. The T3D-L20A-RABF driver can directly perform position control via pulse/direction signals or other communication protocols from a PLC or a dedicated motion control card. It requires a suitable motion controller (PLC, CNC controller, etc.) rather than an additional servo controller.

Some heating is normal for any servo motor. However, if the motor’s surface temperature becomes too hot to touch, or if the driver reports an overheating error, it indicates a problem. Possible causes include overloading (continuous operation above the 2.4 N·m rated torque), low supply voltage, inadequate cooling, incorrect driver parameter settings, or mechanical friction issues. We recommend checking the load status, supply voltage, and driver error codes to diagnose the issue.

The T3D-L20A-RABF driver supports three basic operating modes: position control, speed control, and torque control. Switching between modes can be easily done through the driver’s parameter settings. Typically, the desired control mode is selected via the driver’s software interface or internal DIP switches/keypad, and the relevant parameters are adjusted. For detailed information, please refer to the driver’s user manual.

Mermak CNC offers a 2-year warranty period for the 750W Servo Motor Set 80AST-A1C02430 T3D-L20A-RABF. The warranty covers manufacturing defects and material flaws.
