Frequently asked questions
No, operating the unit with the front cover removed is strictly prohibited due to exposed high voltage terminals and charged sections that pose an electric shock hazard.
Wait at least 15 minutes after turning the power OFF to allow the unit to discharge before starting any maintenance or inspection work.
No, applying a voltage other than the specified value can lead to ruptures or damage to the unit.
Use only the servomotor's hanging bolts for transportation and avoid holding the cables, axis, or detector during the process.
