Jumpers and switches
Jumper / Switch
Description
Positions
J1 (AI1)
Determines whether analog input AI1 is used as a current
or voltage input.
Current (I)
Voltage (U), default.
J2 (AI2)
Determines whether analog input AI2 is used as a current
or voltage input.
Current (I)
Voltage (U), default.
J3 (D2D)
Drive-to-drive link termination. Must be set to terminated
position when the thyristor power controller is the last unit
on the link.
Bus is not terminated,
default.
Bus is terminated.
J4A ... J4D (encoder) OnBoard encoder interface.
J5 (AO1)
Determines whether analog output AO1 is used as a
current or voltage output.
Voltage (U), default.
Current (I)
J6 (grounding)
Digital ground selection switch. Determines whether
DICOM is separated from DIOGND (e.g. the common
reference for digital inputs floats).
See
The insulation voltage between them is 50 V.
DIOGND and DICOM
separated.
DIOGND and DICOM
connected, default.
J7A, J7B
OnBoard encoder interface.
Encoder, default.
Not in use for DCS880.
