JAND4002-20B-DB44 400W High-Voltage Servo Drive 2.9A

The JAND4002-20B-DB44 is a 400W High-Voltage Servo Drive 2.9A rated for 220 VAC supplies and built for compact servo axes that still demand precise, repeatable positioning. Its modest current rating pairs it with smaller servo motors, while the DB44 I/O configuration offers the most complete discrete signal set in its range.

Purpose and Positioning

At 400 W this drive targets light-to-moderate axes in equipment where oversized servo systems would add cost and cabinet space. The generous digital I/O makes it useful in machines that must interface with many limit switches, safety interlocks, and status signals.

Encoder Feedback

The drive supports 17/23-bit absolute encoders, giving it precise, non-volatile position information. This is valuable in semiconductor and battery equipment where axes must return to a known reference reliably after every interruption.

Analog Inputs and Digital I/O

Two analog command inputs accept -10 V to 10 V for speed or torque commands from a PLC or CNC. The DB44 variant provides 8 digital inputs and 5 digital outputs, a comfortable margin for limit switches, safety interlocks, and status reporting.

USB Setup and RS485 Networking

Configuration is handled over a MicroUSB port, and RS485 allows the drive to join a shared network for centralized monitoring and command.

External Braking Resistor

This model has no built-in braking resistor, so regenerative energy during deceleration must be handled by an external braking resistor. If the axis duty cycle involves frequent stops of a high-inertia load, plan for an appropriately sized external resistor.

Protection Functions

Overvoltage, undervoltage, overspeed, and overload protection are built in, isolating the drive and motor from fault conditions.

Typical Applications

CNC machine tools, factory automation, semiconductor equipment, robotics, battery manufacturing, material handling, and packaging machinery are the usual homes for this drive.

Selection Considerations

Confirm that the external braking resistor is sized for your load’s deceleration energy, and verify that the 2.9 A output suits the motor’s current draw. Technical support from Lyenwsin can help you choose the right resistor and I/O wiring scheme.
