8.7 Specifications of HTL Interface Board
Maximum input voltage:
0 - 30 V
Maximum input frequency: approx. 2 MHz
Note:
The maximum input frequency only stands for the cutoff frequency of the square-wave input at PWM 8
(signal source: frequency generator).

Special feature of HTL interface board:
If the inverted are missing at the encoder output, they are generated internally and output
at the encoder output.
