(Note) Contact CKD for chain drives and gear drives.
Operating conditions
1. Index 2. Oscillator
Movement angle (˚)
Moving time t1 (sec.)
Cycle time t0 (sec.)
(Note) Index time is movement time + settling time.
The settling time differs according to the working condition, but generally is between 0.05 and 0.20s.
