Jumpers and switches

Jumper / switch Description
J1 (AI1) Determines whether analog input AI1 is used as a current
or voltage input
J2 (AI2) Determines whether analog input AI2 is used as a current
or voltage input
J3 (D20) Drive-to-drive link termination. Must be set to terminated
position when the thyristor power controller is the last unit
on the link
J4A ... J4D (encoder) OnBoard encoder interface
J5 (AO1) Determines whether analog output AO1 is used as a
current or voltage output
J6 (grounding) Digital ground selection switch. Determines whether
DICOM is separated from DIOGND (e.g. the common
reference for digital inputs floats).
