Description
WS5-9.081-00 is a Berger Lahr rail-mounted five-phase stepper-motor power drive with 24 V control inputs.

It generates a 70 V DC motor circuit from selectable 115 or 230 VAC mains and provides 16 phase-current settings from 0.55 to 2.8 A, step-angle selection, boost, current reduction, direction control and monitored READY output.

Install the IP20 unit inside a control cabinet, preserve the required cooling clearance, set the mains selector before energization, and verify the complete .081-00 suffix rather than substituting the TTL-input .181-00 variant.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What is the main replacement risk when ordering a Berger Lahr WS5-9.081-00 from the secondary market?
A visually similar .181-00 unit uses a different control-signal level, so customers must match the complete suffix, input logic, mains setting, motor current range and connector arrangement.
What must be checked before applying power to a replacement Berger Lahr WS5-9.081-00?
Confirm the 115/230 VAC selector position against the site supply, inspect protective earth and fusing, verify motor wiring and current selection, and ensure the cabinet is dry, clean and adequately ventilated.
Why might a Berger Lahr WS5-9.081-00 trip only after the machine has run for some time?
Restricted cabinet airflow, insufficient spacing, a failing fan, excessive motor current, high ambient temperature or a deteriorating motor cable can produce delayed thermal or phase-interruption faults.
How should motor current be set after replacing a Berger Lahr WS5-9.081-00?
Use the installed motor nameplate and the previous documented setting, start with the approved phase-current stage and verify motor temperature, torque and positioning under controlled load before production.
What should be investigated when a Berger Lahr WS5-9.081-00 reports intermittent motor-phase interruption?
Inspect motor plugs, cable flex points, terminal tightness and winding continuity, then check for vibration-related contact loss; do not repeatedly reset the drive without finding the open circuit.
Can another WS5 variant replace a Berger Lahr WS5-9.081-00 without rewiring?
Not automatically. Confirm signal voltage, mains selector, phase-current range, connector pinout, monitoring behavior and physical clearance before approving any alternate WS5 variant.
What should be documented before sending a Berger Lahr WS5-9.081-00 for repair?
Record the complete label, selector and current settings, LED or fault behavior, operating time before failure, motor type, cabinet temperature and photographs of all wiring so the repair can reproduce the field conditions.
