• The password cannot be set when <F700> = "0". Select a number other then 0 and then set the
password.
• The password can be read out to parameter writer (optional device) until the power is off after
setting <F738>. Please note that password will not be able to read out due to password
protection after the power is off.
• You cannot try inputting <F739> for more than three times. If a wrong password has been input
three times, setting is no longer possible. However, the number of times is reset after power is
off.
