Description

NI  9505  servo drive module

NI 9505 is a full H-bridge DC servo drive module, which is often used in motion control systems and features flexibility and strong customization capabilities.

Functional features:
Strong customability: Working in coordination with the LabVIEW FPGA module, highly customizable motor drivers or actuator amplifiers can be created, and typical applications such as position loops, speed loops, and current loops can be implemented in the block diagram of the LabVIEW FPGA module.
Data feedback: The current data of the motor or actuator can be returned to the LabVIEW FPGA module for current loop control or monitoring. At the same time, it will also return information such as fault status, existence of VSUP and emergency stop status, which is convenient for system monitoring.
PWM signal control: It can generate pulse width modulation (PWM) signals to control the motor and achieve the change of motor rotation direction.
Built-in sensors and interfaces: It is equipped with an encoder interface and a current sensor inside. By using data from the current sensor, the sampling time can be flexibly determined and the motor current can be filtered.

Technical parameters: The working voltage is 24VDC. It is applicable to the ambient temperature of -40 °C≤Ta≤70° C. It complies with relevant certification standards such as Ex nA IIC T4 Gc and can be used in hazardous locations such as Class I Zone 2, Group A, B, C, and D T4.

Application field:
High-precision mechanical processing equipment
It is used for the feed axis drive of CNC machine tools and CNC machining centers. The position closed-loop control is achieved through LabVIEW FPGA to ensure that the motion accuracy of the tool or worktable reaches the micrometer level, meeting the processing requirements of aerospace components, precision molds, etc.

Robot joint drive
As a joint servo unit for collaborative robots or industrial robots, it supports multi-axis linkage control. It monitors the motor load in real time through the current loop to prevent overload damage and is suitable for flexible production lines such as automotive welding and painting.

Solar energy tracking system
In solar photovoltaic power stations, the rotating motors that drive heliostats or photovoltaic panel brackets collect real-time data on the Angle of light, enabling the photovoltaic panels to dynamically track the sun and enhance the utilization rate of light energy. For example, in the control system of a certain solar furnace, NI 9505 precisely controls the pitch and horizontal rotation of the heliostats to ensure the accuracy of high-temperature focusing.

Pitch control of wind energy equipment
The blade pitch system for wind turbines adjusts the blade Angle in real time according to wind speed to optimize the efficiency of wind energy capture. At the same time, it ensures the safe operation of the equipment through fault status feedback (such as overload and overheating).
