Technical data of permitted safety encoders
Designation | Value/description | |
|---|---|---|
Properties | Encoder interface for HTL encoder interfaces A, | |
Permitted safety encoders | EI7C FS, AK0H, AK1H, E.7S, A.7W, EK8S, AK8W | |
Signal level | 0 V to +3 V | Encoder track LOW (logic "0") Encoder track HIGH (logic "1") |
Maximum operating speed EI7C FS, E.7S, EK8W, A.7W, AK8W | 3600 min-1 | |
Maximum operating speed AK0H, AK1H | 6000 min-1 | |
Max. permitted input frequency | 1520 Hz | |
Response time of speed measurement | Calculation formula: Response time of speed measurement in ms = 13 + 7500/n [n] = min−1 | |
Fault response time of speed measurementThe fault response time is the total time from when an internal error occurs or an external error in the encoder circuit is detected until the safe state triggered by the safety card. | No greater than the response time without error. | |
Max. length of the encoder cable | 100 m | |
