Servo electric cylinders rely on encoders for precise motion control. The two main types—absolute and incremental—offer different advantages.
Absolute encoders retain position data even when powered off, enabling immediate operation without homing. They are ideal for high-precision, multi-position, or safety-critical applications. These systems often feature battery-backed cables to preserve multi-turn position memory.
Incremental encoders, on the other hand, provide relative position feedback. After a power loss, the system must return to a reference point, making them a cost-effective option for standard automation tasks.
Comparison Table
| Feature | Absolute Encoder | Incremental Encoder |
|---|---|---|
| Position output | Absolute code (unique value) | Relative pulses |
| Power-off memory | Yes (with battery-backup) | No |
| Startup behavior | Ready instantly | Requires homing to reference |
| Cost | Higher | Lower |
| Typical application | High-precision, safety-critical | General automation, packaging |
