Drive Replacement

Serviceable Parts
u
The drive contains few serviceable parts. The following parts are considered replacement parts on the drive:
• Main control board and I/O 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.
On IP66/NEMA 4X, UL Type 4X enclosure drives, replace the entire unit (drive, enclosure, and heatsink) in the event that
any single part becomes damaged. The drive, waterproof/dustproof enclosure, and heatsink are constructed as a single piece,
and it is not possible to replace the drive separately from the protective enclosure.
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. The charge indicator LED will extinguish when the DC bus voltage is below 50 Vdc. To prevent electric shock,
wait at least five minutes after all indicators are OFF and measure the DC bus voltage level to confirm safe level.
Terminal Board Overview
u
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
by disconnecting the terminal board from the damaged drive then reconnecting the terminal board to the replacement drive.
There is no need to manually reprogram the replacement drive.
Note:
When transferring the removable terminal block with backup memory to a drive with a different voltage class or different output capacity,
set A1-03 to 2220 to initialize the drive after installing the terminal block.

Dismantling the Removable Terminal Block
u
WARNING! Electrical Shock Hazard. Never connect or disconnect wiring, remove connectors or option cards, or replace the cooling fan
while the power is on. Failure to comply may result in serious injury. Before servicing, disconnect all power to the equipment. The internal
capacitor remains charged even after the power supply is turned off.
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.
