β
Series Digital Servo Amplifier
Without External Regeneration Resistor (Using a Jumper)
If you do not have an external regeneration resistor, you must leave the connections on
CX11-2 (DCP and DCC) open. However, you must jumper the CX11-6 (TH1 and TH2)
terminals, shown in the figure below. (This jumper completes the circuit that would
otherwise be completed by the normally closed thermal over-temperature switch in the
external regeneration resistor unit.) If you do not have this jumper installed, the amplifier
will not function. The jumper and its connector are included as a part of the connector kit,
A06B-6093-K305, that is shipped with each amplifier package.

Figure 2-14. Installing a Jumper when an External Regeneration Resistor is not Used
With External Regeneration Resistor
If you have an external regeneration resistor, observe that it has 4 wires. The two smaller
wires (K8) connect to the resistor’s internal, normally closed, over-temperature switch.
This switch will open and shut down the amplifier if the resistor get too hot. The two
larger wires (K7) connect to the resistor. All connectors needed to connect this resistor
unit to the amplifier are provided in the amplifier package.
Connect the two over-temperature switch wires (K8) to CX11-6 terminals TH1 and TH2.
(These connections are not polarity-sensitive.)
Connect the two resistor wires (K7) to CX11-2, terminals DCP and DCC. (These
connections are not polarity-sensitive.)
