Product Introduction & Supply Chain Strategy
This product is a Brand New Surplus unit. It is not used, not pulled from a decommissioned plant, and not refurbished. All modules undergo rigorous quality verification to ensure OEM-level reliability.
The Berger Lahr BLS2020 C162 is a 2-phase stepper motor drive designed for precise position control in automated industrial machinery, packaging equipment, and material handling systems. Sourcing this unit as New Surplus provides a strategic supply chain advantage for plants running legacy production lines. Buying genuine New Surplus guarantees long-term operational integrity and avoids the severe downtime risks associated with degraded capacitor packs in third-party refurbished drives, while eliminating the long lead times of hard-to-find OEM channels.
Installation & Configuration Guide
1.Pre-Installation (Prep & Safety):Disconnect power and verify ESD protection.
Execute lock-out/tag-out (LOTO) protocols on the main 230 VAC feed. Put on an ESD-grounded wrist strap before handling the unit. Take high-resolution photographs of the existing terminal wiring, DIP switch settings, and jumper configurations on the old drive to serve as a precise wiring and logic map.
2.Removal:Extract old unit cleanly.
Unscrew terminal blocks or carefully pull detachable connector plugs without stressing individual wires. Remove the mounting screws securing the chassis to the cabinet wall. Extract the unit straight out to avoid damaging surrounding cabinet components or wiring tracks.
3.Installation (Clone & Seat):Mirror settings and mount secure.
Replicate every DIP switch and jumper position from the original unit onto the new BLS2020 C162. Mount the new drive securely inside the panel using original mounting holes to ensure optimal convective airflow. Reconnect terminal wiring matching your reference photos pin-for-pin.
4.Power-On & Testing:Verify rail voltage and signal responses.
Measure incoming power lines with a multimeter to verify 230 VAC stability before energizing. Restore power and verify the Green ‘POWER/READY’ LED illuminates without triggering a Red ‘FAULT’ indicator. Command a slow manual jog from the PLC or indexer and verify smooth motor step rotation with clean directional changes.

Firmware/Software Versions & Upgrade Notes
- Hardware Compatibility: The BLS2020 C162 relies on hardware-level DIP switch settings and internal resistor networks rather than flashable digital firmware packages.
- Revision Match: Ensure hardware revision codes (C162 variant suffix) match the existing unit on your panel. Sub-variants can feature different current limits or internal logic levels.
- Parameter Backup: Always copy physical DIP switch banks and jumper positions before swapping drives. Changing drive revisions without matching switch layouts can cause motor over-current, excessive heating, or missteps during acceleration.
Frequently Asked Questions (FAQ)
Q: Is this unit truly brand new, or is it a refurbished drive?
A: This product is 100% Genuine New Surplus. It has never been installed in a machine or operated on a factory floor. We maintain a zero-tolerance policy for second-hand or refurbished stock, ensuring you receive true OEM component life without wear.
Q: Why is New Surplus priced differently than OEM list or refurbished parts?
A: Our pricing reflects the market reality of acquiring authentic, original factory inventory globally. It costs slightly more than a risky, repaired unit because you receive unused hardware, yet it costs significantly less than buying directly from legacy OEM channels that impose high markup and multi-week lead times.
Q: What are the risks of buying a refurbished stepper drive for an active production line?
A: Refurbished drives frequently contain aged electrolytic capacitors, worn output transistors, and invisible micro-fissures in solder joints caused by thermal stress. A failed refurbished drive can short motor coils, damage PLC output cards, or trigger unplanned shutdowns that quickly devour any upfront procurement savings.
Q: Is the Berger Lahr BLS2020 C162 a hot-swappable module?
A: No. You must never disconnect or reconnect the BLS2020 while the 230 VAC supply or DC bus is energized. Pulling motor wires or logic connectors under load causes inductive voltage spikes that can permanently destroy power transistors in the drive.
Q: What warranty coverage comes with this drive?
A: Every New Surplus unit comes backed by a comprehensive 1-year functional replacement warranty. Each unit passes complete electrical and terminal continuity checks before shipment to guarantee immediate plug-and-play operation upon arrival.
