The operations are shown below:
(1) Enter the parameter screen after the function key 
on MDI panel is controlled for many times, or press the [Parameter] and [Operation] soft keys subsequently after pressing the function
key 
once.

(2) The parameter screen consists of multiple pages. Use two steps to display the page that
contains the parameter you want to display.
(a) The required relative parameters are selected using the soft key, and then the page to be

found by the page keys or cursor move keys.
(b) The parameter numbers to be displayed are input from keyboard, and press the [search]
softkey to search, then the specified parameter page is displayed, and the cursor is positioned to the
specified parameter (the data part is turned into the selected color).
2 Parameter Setting in the Mode of MDI
The operation steps of parameters setting are shown below:
(1) Enter the offset setting page by pressing the 
, and firstly to input the correspondence password.
To prevent the machining program and CNC parameters from being maliciously modified, the GSK 25i offers an authority setting function and the password can be divided into 9 levels, from the higher to the lower level, such as the 0 level (the system high level), the 1st level (the system service), the 2nd level (the machine manufacturer), the 3rd level (the installation and debugging), the 4th level (the terminal administration), as well as the 5th level (the operator 1 level), the 6th level (the operator 2 level), the 7th level (the operator 3 level) and the lowest default level (see the figure 2-1). The 0 level is enjoys the highest protection; contrarily, the lowest levels are from 5 to 7, and the highest level can be administrated the lowest levels, which is the low authority function. The parameter password level is 3 except for the special explaination.
Fig. 2-1

Volume Parameter
Level 0: the highest authority, reserved by the developer.
Level 1: It is used for the system manufacturer service, which can modified various data.
Level 2: The PLC program, PLC note and the pitch error compensation are modified. The PLC and the pitch error compensation files are input or output. The user customized interface authority is modified/ input or output.
Level 3: The parameter and PLC source data can be modified; the PLC operation is started/stopped; the alarm/operation messages are eliminated; and the files are input or output, and the system, interpolation and positional control maintenance softwares can be upgraded.
Level 4: The program, tool offset, setting, workpiece coordinate system offset and macro program value are modified; these files are input or output and it also has the authority to modify the passward.
The 5th, 6th and 7th levels: it is an operation authorized to corresponding person with bit-parameter by the end user administrator.
The lowest level default by the system: it is an authority operation donated with bit-parameter by end user administrator; no password inputs.
The bit-parameter definitions are authorized by the end user administrator, refer to the following table:

can be selected, and the cursor can be moved based on the password authority to the required items.
(3)Press the 
key, the corresponding level password can be input. If the password is correct, a “correct password” may be displayed in the system; otherwise a “wrong password input” may occur.
(4)After the corresponding parameters are modified, the password is cancelled after logging out.
