Bosch Rexroth LTS350D 0608750125 Servo Amplifier

Description

Key Technical Specifications

Product Introduction & Supply Chain Strategy

The Bosch Rexroth LTS350D (0608750125) is a high-performance LTE servo amplifier module designed for precise AC and EC motor control in automated assembly lines, tightening systems, and robotics. Delivering a 50 A peak current capability with an output frequency up to 1000 Hz, it provides rapid dynamic response and tight torque loops for high-speed industrial motion applications.

Procuring the LTS350D as New Surplus is a high-ROI risk mitigation strategy for legacy machinery. Acquiring a factory-fresh unit eliminates the severe failure risks associated with aged or degraded used drives, ensuring long-term operational continuity while avoiding OEM lead-time spikes and inflated replacement costs.

Installation & Configuration Guide

Stage 1: Pre-Installation (Prep & Safety)

1. LOTO & Power Isolation: Perform Lock-Out/Tag-Out on main cabinet circuit breakers. Disconnect incoming 3-phase AC power lines and wait at least 5 minutes for internal DC bus capacitors to discharge fully.
2. Capacitor Discharge Check: Use a multimeter to verify zero voltage across intermediate DC bus terminals before touching connections.
3. ESD Protection: Put on a grounded anti-static wrist strap before touching drive bus edges or signal feedback connectors.
4. Documentation: Take clear photos of wiring looms, motor power phases (U, V, W), resolver/encoder feedback connections, and DIP switch/address settings on the old module.

Stage 2: Removal

1. Unplug signal cables, encoder harnesses, and control terminal blocks systematically.
2. Disconnect high-voltage DC bus busbars and motor power wiring terminals.
3. Loosen top and bottom mounting screws or DIN locking clips. Carefully extract the drive vertically from the rack assembly without bending rear heatsink pins.

Stage 3: Installation (Clone & Seat)

1. Replicate all DIP switch addresses and hardware jumpers on the replacement LTS350D unit to match original panel documentation.
2. Align the drive housing onto the mounting rack. Fasten retaining screws evenly to guarantee proper thermal contact between the drive rear heatsink and the cabinet panel.
3. Reattach motor power terminals (U, V, W), grounding bonds, and signal feedback connectors, torquing power terminals to standard manufacturer specifications.

Stage 4: Power-On & Testing

1. Verify 24 VDC control power input rails before energizing high-voltage bus circuits.
2. Apply main line power and observe front diagnostic LEDs. Verify the drive boots up into a ready status without axis fault codes.
3. Conduct low-speed jogging in test mode to verify proper motor rotation, torque response, and encoder feedback alignment before returning the machine to full production.

Firmware/Software Versions & Upgrade Notes

• Hardware Compatibility: The LTS350D (0608750125) is a standardized LTE series servo drive module. Physical housing layout and pinout configurations remain identical across production batches for direct drop-in hardware swapping.
• Revision Matching: Verify the hardware revision suffix printed on the drive side label. Ensure parameter sets stored in the host system PLC or drive controller match the drive’s parameter structure.
• Firmware Mismatch Risk: Flashing incorrect or unverified drive parameters can cause axis feedback misalignments, motor hunting, or overcurrent tripping during high-acceleration motion cycles. Always backup parameters from the old drive via software before commissioning a replacement.

Frequently Asked Questions (FAQ)

Is this Bosch Rexroth LTS350D (0608750125) brand new, or was it pulled from an old machine?

This item is 100% New Surplus / Original New stock. It has never been installed in an active control panel, never harvested from a decommissioned manufacturing plant, and never subjected to component-level board repairs. It retains its clean OEM contacts and unaged internal power stages.

How can New Surplus be priced below factory OEM list rates?

New Surplus drives originate from spare inventory reserves, excess system integrator stock, or cancelled automation projects. Sourcing through vetted global supply networks allows us to supply authentic OEM drives at a lower price point while bypassing extended manufacturer lead times.

What are the operational risks of buying a refurbished 0608750125 drive?

Refurbished servo amplifiers frequently contain thermally degraded electrolytic capacitors, weakened IGBT power modules, and worn terminal threads. A catastrophic drive failure on a production line can cause motor runaway or sudden axis stoppage, resulting in tens of thousands of dollars per hour in unscheduled downtime.

Is the LTS350D hot-swappable during machine operation?

No. You must never insert or remove the LTS350D servo amplifier while control power or high-voltage DC bus circuits are energized. Hot-swapping causes destructive electrical arcing across backplane connections and poses severe shock hazards to technical personnel.

What warranty coverage is included with this unit?

This New Surplus LTS350D drive comes backed by a comprehensive 1-year functional replacement warranty. Every unit passes physical inspection and static electrical testing prior to dispatch to ensure out-of-box operation.
