Product Description:
The 109-0780-4801-01 is an AC servo motor encoder built by Bosch Rexroth Indramat and supplied as part of the MAC AC Servo Motors series. It integrates a resolver-based tachometer and an incremental optical encoder, allowing a connected drive to monitor speed and position in real time. In automated assembly lines and handling robots, the motor furnishes controllable torque, quick acceleration, and continuous feedback required for repeatable positioning tasks.
For field installation, the housing carries an IP65 rating, so dust ingress is prevented and low-pressure water jets will not affect the internal electronics. The encoder section draws only 150 mA from the control electronics through a regulated supply of 5 V ±5%, minimizing load on the drive’s auxiliary supply. Bosch Rexroth Indramat installs the sensing disc with a density of 1250 lines; when combined with quadrature decoding this delivers 5000 counted edges per revolution for fine commutation. All position channels are transmitted as a TTL Square Wave, matching the logic thresholds expected by the legacy MAC series drives. The incremental format and standard mounting arrangement simplify interchange with earlier motors in the line.
Signal integrity is maintained at sampling speeds up to 300 kHz, giving the controller ample bandwidth for high-gain velocity loops. Each encoder cycle includes one reference marker, specified as 1 pulse per revolution, and the differential drivers present a high state of ≥2.5 V and a low state of ≤0.5 V. With rise and fall edges contained within ≤200 ns, edge jitter is kept well below the permissible limits of modern digital drives. The integrated tachogenerator supplies 1.5 V per 1000 min-1 and is labeled as a standard tacho type, allowing analog speed feedback when required by hybrid control architectures. Together, the combined tachofeedback with encoder arrangement ensures rapid startup alignment and supports phase failure diagnostics without adding external sensors.
