Encoder type
This page describes the encoder type of the GDM linear unit. The unit can be equipped with different types of linear encoders.
The GDM linear unit can be equipped with different types of linear encoders: incremental, digital, and absolute Hiperface.
Incremental magnetic SIN/COS 1Vpp (default)
Performance
| Parameter | Value |
| Repeatability | +/- 1 increment (with 12 Bit ⇒ ±1 micron) |
| Accuracy | max 1% of period length (with MT10 ⇒ ±10 microns) |
| Power consumption | 25mA typ, 50mA max |
Pinout
| Function | Cable wire colors |
| 0 VDC | Black |
| +5VDC±5% | Red |
| SIN+ | Yellow |
| SIN- | Blue |
| COS+ | Green |
| COS- | Orange |
| Shielding | Shield |
Notes
- The default encoder is the incremental magnetic SIN/COS 1Vpp. - Digital and absolute Hiperface encoders are available on request. - The pinout table shows the cable wire colors for the SIN/COS signals. - Verify the encoder type and the resolution against the application requirements.
