Parameter write enabled even during operation (Pr.77 = "2") • Parameters can always be written. • The following parameters cannot be written during operation even if Pr.77 = "2". To change the parameter setting, stop the operation. 5.3.8 Password Setting a 4-digit password can restrict access to parameters (reading/writing). *1 Although "0 or 9999" can be input in Pr.297 from the PU other than the operation panel, the value is invalid. (The display cannot be changed.) Parameter reading/writing restriction level (Pr.296) • The access (reading/writing) restriction level to parameters in the PU operation mode or NET operation mode can be selected with Pr.296 . ○: Enabled, Ч:
Disabled *1 The parameters affected by the setting of Pr.77 Parameter write selection are not allowed to be written even in the case where "○" is shown. *2 Access to parameters from the command source in the PU operation mode (the PU in the initial setting). (For the PU operation mode command source selection, refer to page 105 .) *3 Access to parameters from the command source in the NET operation mode. (For the NET operation mode command source selection, refer to page 105 .) Locking parameters with a password (Pr.296, Pr.297) • The procedure of locking parameters with a password is as follows. 90 5. PARAMETERS 5.3 (E) Environment setting parameters Pr.

Setting the access (reading/writing) restriction level to parameters locked with a password enables writing to Pr.297. 9999 Password protection disabled. (Writing to Pr.297 is disabled.) 297 E411 Password lock/unlock 9999 1000 to 9998 Input a 4-digit password to lock parameters, or input the valid password to unlock the locked parameters. (0 to 5)*1 (Read only after the parameters are locked.) The number of failed password attempts is displayed when Pr.296 = "101 to 106". The readout is fixed to "0" when Pr.296 = "1 to 6".
(9999)*1 "9999" is displayed when the password protection is enabled (Pr.296 ≠ "9999") but parameters are unlocked, or when the password protection function is disabled (Pr.296 = "9999").
