Optical absolute encoders
The ROQ/EQN 425 rotary encoder by Heidenhain is available with a solid shaft or hollow shaft with a mounted stator coupling and includes TTL and HTL signals.
Heidenhain has expanded EnDat and SSI optical absolute encoders to include additional TTL and HTL signals. The ROQ/EQN 425 rotary encoder is available with a solid shaft or hollow shaft with a mounted stator coupling.
These encoders were designed and developed for a variety of applications, starting with those in the wind energy sector. The absolute signal (EnDat or SSI) within these encoders is used to measure the pitch of the rotor blades as well as the nacelle position. The incremental signals are used (TTL or HTL) for the inverter of the motor.
These encoders are also suitable for applications utilizing decentralized drive technology. The absolute encoder can provide both position and velocity information eliminating the need for an additional encoder.
