    • After registering a password, a read value of P.297 is always 0 to 5.
    • When a password-restricted parameter is read or written, LOCd appears on the display.
    • Even if a password is registered, parameters that the VFD itself writes, such as VFD Parts Life, are overwritten occasionally.
