Voltage range of the encoder inputs
For the connection of unipolar signals, a ground connection at the
CTRL- terminal is adequate for all signals. In view of the possibility of
interference radiation, it is recommended in the case of cables with
lengths of more than 100 m to bypass the four terminals A–, B–, zero
pulse– and CTRL– and to connect to the encoder ground.
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.
