System compatibility

NI-9505 belongs to NI C series motion platform.It is exclusively for CompactRIO chassis,programmed by LabVIEW FPGA,widely used for brushed DC servo motor control,actuator and solenoid drive in automated test and motion prototype systems.It is spare part for legacy automation equipment overhaul.

Function

NI-9505 is rugged C-series H-bridge DC servo drive module.It directly drives brushed DC motors,reads incremental encoder feedback for closed-loop position/speed control.Onboard current sensing and hardware emergency stop protect motor and module from overload fault.

Installation

Insert NI-9505 into CompactRIO chassis slot,tighten front panel screw.Connect motor power to screw terminal and encoder cable to 9pin D-SUB,wire E-Stop signal.Use LabVIEW FPGA programming.Take ESD protection before installation.

Interface

‑9pin D-SUB encoder & E-Stop connector

‑4-pin screw terminal for motor power M+,M-,COM,VSUP

‑C series backplane edge connector

‑Module status LED indicators

Feature

NI-9505 classic NI CompactRIO DC servo drive module.Typical faults:H-bridge power tube burnout,encoder interface damage,overcurrent protection trip.Inspect motor wiring and load before replacement.

Diagnostic

Fault phenomenon:motor no rotation,encoder reading loss,overtemperature shutdown.Check motor power supply,encoder wiring,E-Stop circuit,CompactRIO backplane and module LED status.

Product Brief

NI-9505 is NI C series full H-bridge brushed DC servo drive module supporting 30VDC,5A continuous current,with integrated encoder feedback and E-Stop safety,designed for CompactRIO closed-loop DC motor motion control.Mainly used for maintenance and replacement of old automation equipment.ESD protection must be followed during handling.
