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.
