Drive Replacement

u Serviceable Parts
The drive contains some serviceable parts. The following parts can be replaced over the lifespan of the drive:
• Terminal board I/O PCBs
• Cooling fan(s), circulation fan
• Front cover
Replace the entire drive if the main power circuitry is damaged. Contact your local Yaskawa representative for more
information.
Before replacing any individual parts of the drive, contact your local Yaskawa representative 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 then reconnect
it to the replacement drive. Once transferred, there is no need to manually reprogram the replacement drive.
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.

u Replacing the Drive
WARNING! Electrical Shock Hazard. Do not connect or disconnect wiring while the power is on. Failure to comply can result in serious
personal injury. Before servicing the drive, 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 drive before touching
any 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: Damage to Equipment. 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.
