2.6 Drive Replacement
u Serviceable Parts
The drive contains some serviceable parts. The following parts can be replaced over the life span of the drive:
• Terminal board I/O PCBs
• Cooling fan(s)
• Front cover
Replace the drive if the main power circuitry is damaged. Contact your local Yaskawa representative before replacing parts
if the drive is still under warranty. Yaskawa reserves the right to replace or repair the drive according to Yaskawa warranty
policy.
u Terminal Board
The drive has a modular I/O terminal block that facilitates quick drive replacement. The terminal board contains on-board
memory that stores all drive parameter settings and allows the parameters to be saved and transferred to the replacement drive.
To transfer the terminal board, disconnect the terminal board from the damaged drive and reconnect it to the replacement
drive. There is no need to manually reprogram the replacement drive after transferring the terminal board.
Note: If the damaged drive and the new replacement drive are have different capacities, the data stored in the terminal board cannot be transferred
to the new drive and an oPE01 error will appear on the display. The terminal board can still be used, but parameter setting from the old
drive cannot be transferred. The replacement drive must be initialized and manually programmed.

components.
WARNING! Electrical Shock Hazard. Do not allow unqualified personnel to perform work on the drive. Failure to comply could result in
serious injury. Installation, maintenance, inspection and servicing must be performed only by authorized personnel familiar with installation,
adjustment and maintenance of AC drives.
NOTICE: Observe proper electrostatic discharge procedures (ESD) when handling the drive and circuit boards. Failure to comply may result
in ESD damage to the drive circuitry.
