Connecting the regeneration unit
• When the internal regeneration resistor is used
The driver has an internal regeneration resistor. The driver is shipped with the TH1 and TH2 terminals of
CN1, and RG2 and RG3 terminals of CN3, shorted respectively to enable the internal regeneration resistor.
The internal regeneration resistor does not support continuous regenerative operation, gravitational operation
or other operations involving up/down movements, or frequent repeating of sudden starting/stopping of a
large inertial load. If any of these operations must be performed, use the optional regeneration unit (sold
separately).
• When the optional regeneration unit (sold separately) is used
Use the optional regeneration unit (sold separately) if gravitational operation or other operation involving
up/down movement, or sudden starting/stopping of a large inertia load, will be repeated frequently.

• The two thin lead wires [AWG22 (0.3 mm
2
) for RGB100, AWG20 (0.5 mm
2
) for RGB200] of the
regeneration unit are thermostat outputs. Connect them to the TH1 and TH2 terminals using the CN1
connector.
• Regenerative current flows through the two thick lead wires (AWG18: 0.75 mm
2
) of the regeneration unit.
Remove from the CN3 connector the jumper wire which has shorted the RG2 and RG3 terminals, and
connect the lead wires to the RG1 and RG3 terminals.
Note
• When connecting the optional regeneration unit (sold separatery), be sure to remove
the jumper wires from the CN1 connector and CN3 connector.
• If the current consumption of the regeneration unit exceeds the allowable level, the
thermostat will be triggered and a regeneration unit overheat alarm will generate. If a
regeneration unit overheat alarm generates, turn off the power and check the content of
the error.
