Connecting an External Regeneration Resistor

R88D-KP01H/-KP02H/-KP04H
Normally B2 and B3 are open.
If an External Regeneration Resistor is necessary, connect the External Regeneration Resistor
between B1 and B2 as shown in the diagram below.
Servo Drive
Precautions for Correct Use Precautions for Correct Use
Connect the thermal switch output so that the main circuit power supply is shut OFF when the
contacts open.
When using multiple External Regeneration Resistors, connect each thermal switch in series.
Fire or burn damage may result due to the temperature rise in the resistors if the Servo Drive is
used without setting up a power supply shutoff sequence using the output from the thermal
switch.
R88D-KP08H/-KP10H/-KP15H/-KP20H/-KP30H/-KP50H/
Normally B2 and B3 are shorted.
If an External Regeneration Resistor is necessary, remove the short-circuit bar between B2 and B3,
and then connect the External Regeneration Resistor between B1 and B2 as shown in the diagram
below.
