System Architecture & Signal Flow
The HR500 BLJC-08R module operates within the HR500 modular rack architecture. The signal flow is as follows:
- Command Input — Velocity or position reference received from the host PLC or motion controller via the HR500 backplane
- Drive Processing — Internal DSP computes PWM output based on closed-loop error signal
- Power Stage Output — Three-phase AC output delivered to the servo motor
- Feedback Loop — Encoder/resolver signals returned to the drive for real-time correction
- Fault & Status — Drive status and fault codes reported back to the PLC via backplane communication
Sourcing & Quality Verification
- All units are sourced from verified industrial surplus channels and decommissioned OEM installations
- Each module is visually inspected for physical damage, corrosion, and component integrity
- Functional power-on testing performed where applicable
- Serialized tracking maintained for full traceability
