10. SPECIFICATIONS
The standard shaft of the servo motor is straight without a keyway. Shafts with keyway and D cut
are also available.
These shafts are not appropriate for applications where the servo motor is started and stopped
frequently. Use a friction coupling or the like with such keys since we cannot guarantee such trouble
as broken shafts due to loose keys.
