4.1.6 Parameter Values that Cannot be Changed
In some cases, you cannot change parameter values. If this is the case, an error
message is displayed when you try to select it. The situations in which you cannot
change parameter values are:
• When the drive is running and the parameter you are changing is configurable.
Configurable parameters cannot be changed while the drive is running or jogging.
Stop the drive to change the parameter.
• When programming protection is enabled. See section 4.2 of this chapter for more
information.
• If the parameter is read-only (output). Read-only parameters can only be viewed.
4.2 Using a Password to Protect Programming
To prevent changes to parameters, you can use program protection. Program
protection prevents changes to parameters, and to the language and contrast settings.
It does not affect:
• keypad control, including the manual reference
• fault and alarm options
• monitor mode
• language setting
• display contrast adjustments
PROGRAMMING DISABLE (P.051) toggles program protection. If program protection
is enabled, this procedure disables it. If it is disabled, this procedure enables it.
When password program protection is enabled and you select a parameter, the
message “Do you wish to enter the password to DISABLE program protection” is
displayed. If you select YES, you must enter the factory-set password to change the
parameter.
Note that disabling software program protection for one parameter disables it for all
parameters. To re-enable software program protection, repeat the following procedure.
Important: The OIM is not affected by the setting of the Second Menu Password
(P.006).
To enable or disable programming:
Step 1. Press until the key indicator reads PROGRAM.
Step 2. Go to the Main Menu by pressing until GV3000 Main Menu is
displayed at the top of the screen.
