Incremental encoders

The GI357 is designed according to SIL2 (Safety Integrity Level 2) and can be used in critical applications such as elevators and other moving systems where human safety is an issue. The safety function must be implemented in the control system. Control of inphase signals. Direct and inverse signal lines must always have an antiphase signal level. Transient states in which the outputs have the same signal level must not exceed a few microseconds. If this time is exceeded, the self-diagnostics of the encoder detects this as a defect and issues a corresponding signal. Line break monitoring. Do not use supply cables (signal lines) with high electrical resistance. The high resistance of the encoder outputs transmits the alarm signals from the encoder itself to the control system. Shaft speed monitoring. If the allowable shaft speed limit is reached, the higher control system monitors the output frequency. If the output frequencies are not identical (different), the system recognizes the defect. Control of the direction of rotation of the shaft. The phase offset of the output signals must be 90°, deviations from this value are monitored. The direction of rotation of the shaft must be monitored accordingly. If there is no change in the state of at least one output, the second output must be monitored and only then the system signals that the encoder shaft is stationary, i.e. that the rotation has stopped.
