6.5 Regenerative Unit Replacement
◆ Serviceable Parts
The regenerative unit contains some serviceable parts. The following parts can be replaced over the life span of the
regenerative unit:
• Terminal board I/O PCBs
• Cooling fan (s)
• Front cover
Replace the regenerative unit if the main power circuitry is damaged. Contact your local Yaskawa representative before
replacing parts if the regenerative unit is still under warranty. Yaskawa reserves the right to replace or repair the
regenerative unit according to Yaskawa warranty policy.
WARNING! Electrical Shock Hazard. Do not inspect, connect, or disconnect any wiring while the power is on. Failure to comply can
result in serious personal injury. Before servicing the regenerative unit, disconnect all power to the equipment. The internal capacitor
remains charged even after the power supply is turned off. After shutting off the power, wait for at least the amount of time specified on
the regenerative unit before touching any components.
◆ Terminal Board
The regenerative unit has a modular I/O terminal block that facilitates quick regenerative unit replacement. The terminal
board contains on-board memory that stores all regenerative unit parameter settings and allows the parameters to be saved
and transferred to the replacement regenerative unit. To transfer the terminal board, disconnect the terminal board from
the damaged regenerative unit and reconnect it to the replacement regenerative unit. There is no need to manually
reprogram the replacement regenerative unit after transferring the terminal board.
