3.3 DC-link (X1B)
To bridge the DC-link voltage with other servo amplifiers, the X1B/2 (+DC) and 3 (-DC)
connectors can be used.
The intermediate circuit power can be distributed to different servo amplifiers with this
method.
Note: If the intermediate circuit is bridged within a group of amplifiers,
the main power supply in this group must also be bridged.
3.4 External Regen Resistor (X1B)
If the power of the internal brake resistor is insufficient, an external resistor can be added.
Here, the connection to R
int
(terminal 4 of X1B) and R
tr
(terminal 5 of X1B) must be
removed. The external resistor is connected to terminal 2 and 5 of X1B. The fuse on both
connections of the external brake resistor is mandatory. 1000 VDC fuses with slow trigger
characteristics must be used.
Note: The brake resistor fuse does not protect the resistor, rather the
connected cable in the event of a short circuit. The amplifier has
electronic protection for the brake resistor.
