WARNING
Incorrect data is output if the maximum speed is exceeded
The dangerous state may not be stopped or not be stopped in a timely manner in the event of
non-compliance.
The target safety-related level may not be achieved in the event of non-compliance.
►
Observe maximum speed.
►
Only use suitable encoders for the application.
1
Resistance between ENCx_y+/– and ENC_0V.
2
Resistance between ENCx_y+/– and ENC_0V. An input voltage of 30V between ENCx_y+/– and ENC_0V
w
ill not damage the module, e.g., in the event of voltage limiting, if the voltage exceeds 5V.
3
Resistance between between ENCx_y+ and ENCx_y– with series capacitor to block direct current load. An
input voltage of 30 V will not damage the module.
4
Voltage between A1 of the main module and ENCx_24V at 0.2A sum load current.
6
Voltage between ENCx_y+ and ENCx_y–.
7
Voltage between ENCx_y+ and ENC_0V as well as between ENCx_y– and ENC_0V.
8
Voltage between ENCx_y+ and ENCx_y– with a terminator of ≥60Ω.

Plus the resolution of the speed information based on the resolution of the encoder system:
a) Rotational movement in rpm = 15,000/(4 × number of A/B periods per revolution)
b) Linear movement in mm/s = 250/(4 × number of A/B periods per revolution)
10
Plus the resolution of the position information based on the resolution of the encoder system:
1rev./(4 × number of A/B periods per revolution).
11
Master and listener mode.
12
Time between the falling edges of the clock.

Without start bit. If repeat transmission is used (clock continues without clock gap so that the same data
can be transmitted again), the entire stream is viewed as a frame.
