Characteristics
- This reduces the vibration in the resonance area of a stepping motor.
- This supports the follow - up to pulse speed of a stepping motor in high speed zone to improve the max. rotational frequency.
- Allowable operating temperature: - 10°C to 40°C
- Bore - completed products. Special processing is not required.
