Product Description:
The PCE845-XYZ-N is a brushless servo drive produced by Pacific Scientific for the PC800-PCE800 Brushless Servo Drives series. It converts incoming three-phase power into controlled motor currents so rotary axes can be positioned quickly and accurately in packaging machines, pick-and-place gantries, and other industrial automation cells. The unit combines a regulated bus supply with high-frequency pulse-width modulation to support closed-loop torque, velocity, and position control when paired with compatible permanent-magnet servomotors.
Its continuous phase capability is 7.5 ARMS, allowing it to drive medium-frame motors throughout demanding duty cycles, while short bursts up to 22.5 ARMS accommodate acceleration or shock loading. The power section accepts a three-phase source at 480 VAC and converts it to a regulated 640 VDC bus before switching at a 16 kHz frequency; this combination yields a 97% conversion efficiency that helps limit panel heat. Excess kinetic energy is dissipated by an internal regeneration path rated at 100 W through a 33 ohm resistor. The housing measures 146.7 mm in width, 192 mm in depth, and 254 mm in height, allowing the module to fit in control cabinets with limited space.
Integration with digital motion controllers is simplified by the SERCOS command interface, which provides deterministic fiber-optic communication for synchronized multi-axis networks. Position feedback is resolved internally to 24 bits/rev, permitting fine interpolation without relying on external scaling routines. During emergency deceleration, the shunt regulator can divert up to 20 kW into an external brake resistor, extending the drive’s transient energy handling beyond the onboard path. The drive weighs 4.2 kg, and its mounting arrangement leaves rear clearance for airflow and cable routing.
