Incremental Encoder Specifications
Output signals are incremental with edge evaluation, and channel separation should be 90 ±25 el°. The duty cycle is typically 180 elº or 1:1. Each encoder is verified for accuracy, channel separation, and duty cycle.

Bearing Lifetime and Shaft Load
Lifetime is influenced by shaft bearings, load, speed, and temperature. High-quality lubricated bearings are used, with nominal dynamic shaft loads specified for a service life of approximately 50,000 hours at 1500 rpm. High-quality shaft-coupling and bearing boxes are recommended to minimize shaft load.

Vibration and Shock
Maximum vibration values apply for frequencies between 55 to 2000 Hz, and shock values are valid for 6 ms. Avoid using hammers for adjustments.

Incremental Signals and Fault Detection
Incremental signals are transmitted as digital square-wave pulse trains, phase-shifted by 90 degrees, with a reference mark signal and inverse signals for noise-proof differential transmission. A STATUS signal indicates fault conditions, useful for machine shutdowns during automated production.

speed. Therefore, the actual operating temperature shouldbe measured directly at the encoder if the encoder isoperated near the limits of permissible parameters. Thensuitable measures should be taken (fan, heat sinks, etc.) toreduce the ambient temperature far enough so that themaximum permissible operating temperature will not be exceeded during continuous operation.For high speeds at maximum permissible ambienttemperature, special encoder versions are available on request with reduced degree of protection. > The maximum permissible shaft speed or traversing velo-city of an encoder is derived...
