EIS Indexing motor series
Standard type of hydraulic indexing motor
- ● Hydraulic motor for indexing
- ● High torque, high speed indexing and space-saving solution
- ● Smooth and shock-less indexng by built-in mechanical valve
- ● Index accuracy: ±0.1° on the output shaft
To adjust initial setting
| Symptom case | Adjust setting if below symptom happens |
|---|---|
| When motor stops, shock is detected. （Revolution speed is not reduced） | Turn counter-clockwise |
| After motor stops beyond the designated point, motor back to there. | Turn counter-clockwise |
| Motor doesn’t reach to the designated point. | Turn clockwise |
| After revolution speed is reduced, motor runs slowly then reach to the designated point. | Turn clockwise |
How to adjust initial setting
- 1: Loose bearing nut (34mm) mounted in mechanical valve sleeve then remove it.
- 2: Grab mechanical valve sleeve by hand tool like spanner then turn sleeve by 90 degrees, and fix it when the suitable position is found.
- 3: Tighten bearing nut by hand tool.
- 4: Conditions when motor stops do NOT seem to be good during process 2, change the gain.
