Product Description:
The PD2406Di-001-E is an intelligent servo drive produced by Pacific Scientific for the PC3400 Servo Drives series. The unit combines embedded motion control with power electronics to regulate brushless or brushed servomotors in automated machinery. By closing current, velocity, and position loops internally, it offloads the host PLC and allows decentralized axis control in conveyor sections, pick-and-place heads, and other industrial automation systems. Its onboard processor and memory resources support parameter storage and deterministic motion-profile execution without an external computer, reducing the amount of control hardware required for each axis.
A Thompson F168 CPU operates at 20 MHz, providing the deterministic timing base for the drive’s control cycles. The power stage supplies a continuous phase current of 6 ARMS and can deliver a sustained mechanical output of 2.3 kW when the connected motor and bus voltage permit. For acceleration and disturbance rejection, the drive delivers up to 12 ARMS for short periods. The DC bus accepts an input range of 18–74 VDC, allowing the unit to operate with compatible battery packs or low-voltage rectifiers in mobile equipment and compact machines. The drive includes 256 KB of flash memory for its operating software and motion tables. It also provides 256 KB of RAM for real-time variables, temporary operating data, and diagnostic records generated while the axis is running.
The current-control algorithm refreshes every 102.4 µs, allowing the power stage to respond quickly to changing torque demand and motor current. Velocity calculations are updated every 408 µs, supporting stable speed regulation when the mechanical load varies during operation. Position calculations run every 2.0 ms, enabling the drive to follow programmed trajectories and coordinate multi-segment moves. The Standard Unit customization designation indicates that the installed options, input and output mapping, and feedback interfaces follow the baseline configuration for this model. This arrangement provides a consistent control structure for applications that use the drive as a self-contained motion-control node. Stored motion programs can execute directly on the drive while the host controller exchanges commands, operating states, and fault information with the axis.
