2.11.2 Connection and jumpers presetting with System2 board
1) Check the mechanical installation of the encoder according to producer specifications.
2) Check that the presetting for the encoder power supply and the jumpers on the control board are correct
The three pins jumpers P1, P2 and P3 allow to insert the termination of the three encoder lines available on connector with removable
terminals J3 “SYSENC” module (respectively line A, line B and line Z). It is possible to insert two different values of termination resistors, 110
or 220. The table below shows the possible configurations.
