Connecting the regeneration unit
Connect the accessory regeneration unit if gravitational
operation or other operations involving up/down
movement, or sudden starting/stopping of a large inertial
load, will be repeated frequently.
The two thin lead wires (AWG22: 0.3 mm
2
) of the
regeneration unit are the thermostat outputs. Connect
them to the TH1 and TH2 using the CN1 connector.
Regenerative current flows through the two thick lead
wires (AWG18: 0.75 mm
2
) of the regeneration unit.
Connect them to the RG1 and RG2 using the CN4
connector.

Before connecting the regeneration unit, be sure to remove the jumper wire from the CN1
connector.
If the allowable power consumption of the regeneration unit exceeds the allowable level, the
thermostat will be triggered and the regeneration unit overheat alarm of the driver will generate. If
the regeneration unit overheat alarm generates, turn off the power and check the connection or
operating condition.
