changing the corresponding parameter.
2. Total load capacity of the Auxiliary voltage output +24V (X2:10) is 6.0 W (250 mA / 24 V) minus the power
taken by the option modules installed on the board.

Ground the outer shield of the cable 360 degrees under the grounding clamp on the grounding shelf for the
control cables.
Further information on the usage of the connectors and switches is given in the sections
below.

Switch
TERM Drive-to-drive link termination. Must be set to the terminated
(ON) position when the drive (or another device) is the first or
last unit on the link.
BIAS Switches on the biasing voltages to the bus. One (and only
one) device, preferably at the end of the bus must have the
bias on.
