Target Wheel
The target wheel detected by the sensor head has three structural options for the reference position:
Flag – Slot – Teeth
Each structure has distinct characteristics, allowing you to choose based on your specific needs:
- Flag: Not suitable for high-speed rotation due to structural imbalance, but advantageous in terms of cost.
- Slot: Offers better balance compared to the flag type.
- Teeth: Less cost-effective but provides excellent balance due to being machined, capable of handling speeds up to 100,000 min-1.
Output Signal Waveform
The output signals from the rotary encoder consist of two-phase rotation signals and one-phase reference position signal. The two types of signals output by the rotary encoder are:
- U1, U2: These signals are used for rotation control. You can choose between square wave or sine wave, depending on the specifications of the connected controller.
- UN: This signal is used for positioning control and is output once per revolution. You can choose between a flat (left diagram) or a peaked (right diagram) waveform.
Digital Communication
We provide products compatible with various communication protocols from different manufacturers (some still under development).
On-line Inspection Module GEL211
The on-line inspection module GEL211 allows for the verification and signal correction of the following items in an on-machine state.
- Operating Statistics: Determines the operational duration within various speed ranges.
- Cumulative Operating Time: Tracks the total operating time.
- Signal Waveform: Monitors signal quality.
- Gear Damage Detection: Identifies damage to gears.
- Signal Correction: Performs signal adjustments.
Signal correction and confirmation of accumulated operating time can be done from a PC, tablet, etc. Also, you can set and check from the following browsers you are already using without installing special software.
- Firefox 10+
- Safari 5.0+
- Chrome 16+
- Opera 10+
