Product Description:
Okuma manufactured the MDUF-15-2844-MA, a multi-axis servo spindle drive unit designed for CNC applications that require precise control. The unit is a servo spindle drive that makes it possible for the spindle to work accurately in multiple directions.
The MDUF-15-2844-MA servo spindle drive unit can work consistently when the humidity or temperature is between 20% and 85% RH and the temperature is between 0°C and 40°C. The servo drive can be installed at heights of up to 1000 meters without losing its grade, and it can work in places where vibrations are less than 0.5 G. The unit can handle DC voltages between 283V and 325V. The output is AC 200V, 3-phase, and the frequency can be changed. The current ratings range from 1.6A to 11.2A, 8.6A to 5.3A, 4A to 2A, and 1.6A, based on how the motor is set up. The limit for short-circuit current is 50kA RMS symmetrical. For motor phases, the power output connections are marked with U, V, and W. The other labels are PA, PB, PC, and PD. E1A, E2A, E1B, E2B, EPG, PGL, PGC, E1S, EPGF, RES, and CHG are the names of the signal and communication devices. BB, BR, BD, E1C, E2C, E1D, and E2D are some of the control and feedback links. The servo drive has axis labels that show that SA is marked as U1 and that the X and Z axes are not given.
The MDUF-15-2844-MA servo spindle drive unit has an interface board that can be seen through the top hole and is used for connecting the encoder input. This item is utilized in CNC-based industrial automation systems that need dependable control over multiple axes. With a value of 50kA, the SCCR can handle a lot of faults. Through separate output terminals, the device gives precise control over motor phases.
Frequently Asked Questions about MDUF-15-2844-MA:
Q: How does MDUF-15-2844-MA handle high fault levels?
A: It has a 50kA SCCR rating. This protects connected systems during short-circuit events without internal damage.
