Product Description:
The BLIII-D15A Servo driver is a product of Okuma BL Servo Drives family products. The product serves high quality automation requirements and motion control operations.
The BLIII-D15A servo drive converts electrical input power into mechanical output with minimal losses as it reduces energy waste, runs cooler and can help lower operating costs over time. The tests or output points used for monitoring its performance are velocity command, torque command, load, phase U current command, phase U current feedback, phase V current feedback and DC bus voltage. It can accept the AC main voltage in the range 70 to 242 V AC and it supports global standard frequencies (50 or 60 Hz). It is adaptable to different power environments without additional conversion equipment. It is featured with built in functions such as overcurrent which provides protection against excessive current draw, under/over voltage which ensures the drive shuts down or warns when voltage is too low or too high. It also includes a CPU malfunction feature which monitors the internal processing unit to ensure the drive logic is operating correctly.
The BLIII-D15A servo drive can supply to the motor maximum continuous current of 15 amps. It uses LEDs to display its current status, such as power on, fault, operating or standby which provides a quick, visual way to assess system health. It is built to last in demanding environments. It is designed to work with motors or systems that require a 15-amp interface and ensures electrical compatibility and optimal performance. The module can serve as a drop-in replacement for older or different models (BDU and BL-D) which simplifies system upgrades or maintenance without major rewiring or reconfiguration.
Frequently Asked Questions about BLIII-D15A:
Q: Why is phase current feedback important in the BLIII-D15A servo drive?
A: Phase current feedback ensures precise current control in each motor phase. It helps improve torque accuracy and protect the motor during dynamic load changes.
Q: How does the adjustable current limit protect the BLIII-D15A from electrical damage?
A: It restricts the maximum output current to prevent overloads. This feature enhances the longevity of both the servo drive and the connected motor.
Q: What role does the torque command terminal play in motion control?
A: The torque command input allows fine control over motor torque during operation. It's essential for load-sensitive or high-precision industrial applications.
Q: Why is the 50/60 Hz frequency support important in BLIII-D15A servo drive?
A: It ensures global compatibility with electrical grids. Users can deploy the unit in different regions without needing frequency converters.
Q: How does LED status indication improve the usability of BLIII-D15A servo drives?
A: LEDs provide real-time visual feedback of operating conditions. This simplifies diagnostics and reduces downtime during troubleshooting or maintenance.
