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 sepa-
rated
DIOGND and DICOM con-
nected, default
