National Instruments 778005-01 Servo Motor Drive 

National Instruments part number 778005-01 is an identifying part number for the MID-7654, a Servo Motor Drive. The MID-7654 is a 4-axis, 400 W, Elmo Motion Control Servo Motor Drive designed for NI-7350 and NI-7340 motion controllers. It is a 4-axis version of the NI MID-7652. The NI MID-7654 has multiple safety features. Apart from its capability to utilize a 5VDC host bus power signal, it can also detect crucial signals like overload and over-temperature signals, prompting either a complete or partial shutdown when necessary. 

The MID-7654 stands out as a fully integrated solution tailored for demanding industrial applications. Featuring high-efficiency and exceptionally reliable PWM amplifiers set up to function as torque blocks (either transconductance amplifiers or current amplifiers), this drive offers robust performance. 

Moreover, with this model, you can seamlessly connect all encoders, I/O motors, and limit switches directly to NI motion controllers. The encoder differential input threshold of the system is typically ±0.3 V, ensuring precise signal reception. Its analog inputs feature a noise filter with an RC time constant of 10 μs, optimizing signal clarity. For user convenience, a 5 V supply with a voltage range of 4.7 to 5.2 V at 0.5 A is provided. The power supply input voltage is compatible with a wide range, spanning from 90 to 132 VAC or 198 to 264 VAC, with a frequency range of 47 to 63 Hz. 

Additionally, it falls under Installation Category II, ensuring suitability for various installation environments. The Peak Current Limit for 2.7 seconds ranges from 1.7 to 10 A, with a default setting of 1.7 A. Continuous Current Limit ranges from 0.85 to 5 A, defaulting to 0.85 A. When considering the Continuous Power Output Rating for all axes combined, it stands at 400 W with a 25% duty cycle.
