Product Description:
The PCE835-001-T servo drive is produced by Pacific Scientific in the PC800 - PCE800 Brushless Servo Drives series. It supplies regulated three-phase power to brushless servo motors and closes velocity, torque, and position loops for packaging lines, assembly cells, and other automated stations. A high-speed digital signal processor and an integrated power stage translate motion-controller commands into pulse-width-modulated output while reporting status data back to the host PLC. This arrangement allows the drive to manage motor current quickly during acceleration, indexing, and steady-speed operation.
At 40 °C, the drive can deliver a continuous phase current of 7.5 ARMS, corresponding to a continuous mechanical output of 5.6 kW when the line supply is 480 VAC. When an external blower is installed, the available continuous current rises to 11.25 ARMS, allowing higher load duty without thermal derating. Startup stresses are handled by an inrush peak of 175 A, and the internal bus capacitors absorb this transient within safe limits. Motor leads may be run up to 50 m before additional output filters are needed, which simplifies installation on large machines. The controller accepts motors whose inductance is as low as 1.7 mH, and the rms line current drawn from the supply is 11.0 ARMS during rated operation.
For short bursts, the power stage can source 22.5 ARMS for three seconds, producing up to 19.2 kW of peak mechanical power during that interval. Power conversion efficiency reaches 97%, so only a small portion of the input energy is lost as heat at full load. The insulated-gate drivers switch at 16 kHz, balancing acoustic noise with current ripple, and control variables are refreshed every 62.5 microseconds to maintain tight loop bandwidth. Regenerative energy is routed to a 33 Ω resistor, and if braking demand exceeds the 100 W standard channel, the 20 kW shunt path protects the DC bus. The permissible motor inductance extends to 1.7 H, covering a broad range of Pacific Scientific servomotor models.
