Description
The National Instruments NI-9514 C Series Motor Drive Interface Module, part numbers 780110-01 and 782906-01, falls under the C Series Motion category. This module is designed to interface with motor drives, offering a comprehensive solution for motion control applications.
The board only version of this module is identified by part number 782906-01. It provides flexibility in connecting to various types of motor drives through its AKD Cable for AKD analog servo drive, and a terminal block for external servo drives. This ensures compatibility with a wide range of servo drive models.
For precise control, the module outputs an analog drive command with a voltage range of ±10 V, featuring an analog output resolution of 16 bits. This high resolution allows for smooth and accurate motor control.
The NI-9514 supports encoder feedback with two phases (A and B) and an Index input, accommodating both RS-422 differential and single-ended inputs. The encoder power output is provided at +5 V, suitable for a wide range of encoders.
In terms of power consumption, the module is efficient, requiring up to 900 mW when active and a maximum of 0.4 mW in sleep mode. This efficiency is crucial for reducing overall system power consumption.
The drive enabled signal is software-operated and can be configured for either sourcing or sinking output, offering flexibility in integration with different systems. The module supports both torque loop and position loop control modes, with a maximum control loop rate of 20 kHz in position loop mode, ensuring high-speed response in dynamic applications.
