The inputs are non-floating. The rough pulse is smoothed with 0.7 ms,
and the fine pulse with approx. 200 ns.
The SBP board is designed as a PELV circuit (Protective Extra Low
Voltage). The earth of the SBP board is connected with the PE
conductor (earth) inside the device.
The encoder is provided with signals of track A+, B+ and an additional
zero pulse.
In order to avoid any interference radiation on the signals, you should
bypass terminals A-, B-, zero- and CTRL- and connect to the encoder
ground.
The screen of the encoder line must be connected to ground over a
wide area, both on the motor side and on the converter side.
