Parameter Protection Password Input

Display
 This parameter allows you to enter your password (which is set in Pr. 00-08) to unlock the
parameter protection and to make changes to the parameter.
 To avoid problems in the future, be sure to write down the password after you set this parameter.
 Pr. 00-07 and Pr. 00-08 are used to prevent personnel from setting other parameters by accident.
 If you forget the password, clear the password setting by entering 9999 and pressing the ENTER
key, then enter 9999 again and press ENTER within 10 seconds. After decoding, all the settings
return to default.
 When setting is under password protection, all the parameters read 0, except Pr. 00-08.
 Parameter Protection Password Setting
Settings 0–65535
 This parameter is for setting the password protection. Password can be set directly the first time.
After you set the password, the value of Pr. 00-08 is 1, which means password protection is
activated. At this time, if you want to change any of the parameter settings, you must enter the
correct password in Pr. 00-07 to deactivate the password temporarily, and this would make Pr.
00-08 become 0. After you finish setting the parameters, reboot the motor drive and the
password is activated again.
 Entering the correct password in Pr.00-07 only temporarily deactivates the password. To
permanently deactivate password protection, set Pr.00-08 to 0 manually. Otherwise, password
protection is always reactivated after you reboot the motor drive.
 The keypad copy function works only when the password protection is deactivated (temporarily
or permanently), and the password set in Pr. 00-08 cannot be copied to the keypad. So when
copying parameters from the keypad to the motor drive, set the password manually again in the
motor drive to activate password protection.
