Jumper selections
On the OPTA4 board, there are two jumper blocks. The jumper X2 is used to define the status of the
termination resistor (R=135Ω). The jumper X4 is used to program the control voltage (auxiliary
voltage). The factory default and other available jumper selections are presented below.

NOTE: If one encoder is connected to one
drive only, the termination resistor on the
board must be used. If the encoder is con-
nected to several drives, the termination
resistor of the last drive must be used.
