Product Description:
The PC833-XYZ-N Brushless Servo Drive, made by Pacific Scientific, has an input power supply range of 115–240 VAC to ensure that it meets typical electrical installations within different regions. With a continuous output current of 3.6 Arms within the ambient temperature range of 25–40 °C, this servo drive maintains a stable and accurate control during extended use.
Under dynamic motion requirements, the PC833-XYZ-N drive provides a peak output current of 10.6 A RMS for high-acceleration motion or rapid load change. This servo drive is designed to operate over a broad voltage input range of 90–265 VAC, which is compatible with both single-phase and three-phase systems, thus enabling flexible integration. This brushless drive is configured to provide a maximum output power of 4.5 kW for adequate capacity to drive medium to high-torque motors in precision automation applications. To protect internal elements during power-up, the PC833-XYZ-N brushless drive limits the inrush peak current to 300 A. This drive also has a built-in bus capacitance energy absorption circuit, with a rating of 30 joules to handle regenerative energy and for protection from voltage spikes. This energy absorption comes from a 320V nominal DC bus, which leads to stable operation during high-speed deceleration or braking.
The frequency of this drive’s output current ripple is kept at 20 kHz, which reduces electrical noise and increases performance in sensitive control applications. This PC833-XYZ-N Brushless Servo Drive is provided with multiple interface choices, which are RS-232/485, ±10V DC analog, and Step/Direction with Preset Indexing. These options allow easy connection to legacy PLC systems as well as newer CNC or motion controllers without any problems. The physical design of this brushless drive involves measurements of 7.8" x 3.47" x 6.22" and a miniaturized weight of 2 kg to utilize panel space effectively. For protection, this drive has a Bussman MDA-20 fuse, which offers effective current limiting in fault conditions.
Frequently Asked Questions about PC833-XYZ-N:
Q: How does the 30 J energy absorption improve the drive's performance?
A: It protects internal circuitry by handling regenerative energy during motor braking. This ensures voltage stability during deceleration phases.
Q: Why does the PC833-XYZ-N use a 20 kHz ripple frequency?
A: This high ripple frequency reduces audible noise and improves motor smoothness. It also minimizes interference in nearby sensitive equipment.
Q: What is the role of the Bussman MDA-20 fuse in the drive?
A: It protects against overcurrent faults by breaking the circuit quickly. This helps prevent internal damage to the PC833-XYZ-N during power anomalies.
Q: How does Step/Direction input enhance motion control compatibility?
A: It allows easy integration with stepper-based systems and low-cost controllers. This improves positioning precision in CNC and indexing applications.
Q: What benefits does the wide voltage range of 90–265 VAC provide?
A: It allows the PC833-XYZ-N to operate in different global environments. This is useful for systems that relocate or are built for export.
