4.2.33 User group selection (Pr. 160, Pr. 173 to Pr. 176)
Pr. 160 "user group read selection"
Pr. 173 "user group 1 registration"
Pr. 174 "user group 1 deletion"
Pr. 175 "user group 2 registration"
Pr. 176 "user group 2 deletion"
Among all parameters, a total of 32 parameters can be registered to two different user
groups. The registered parameters may only be accessed.
The other parameters cannot be read.
Parameter Number Factory Setting Setting Range Remarks
160 0 0, 1, 10, 11
173 0 0 to 999
174 0 0 to 999, 9999 9999: Batch deletion
175 0 0 to 999
176 0 0 to 999, 9999 9999: Batch deletion
<Examples of use>
(1) Parameter registration to user group
Write the parameter numbers to be registered to Pr. 173 (user group 1 registration)
or Pr. 175 (user group 2 registration). Write the parameter numbers one by one.
(2) Parameter deletion from user group
Write the parameter numbers to be deleted to Pr. 174 (user group 1 deletion) or
Pr. 176 (user group 2 deletion). Write the parameter numbers one by one.
(3) Set the required value in Pr. 160 to make the user group or groups valid or invalid.
Pr. 160 Setting Description
0 All parameters are accessible (factory setting)
1 Only the parameters registered to user group 1 are accessible.
10 Only the parameters registered to user group 2 are accessible.
11 Only the parameters registered to user groups 1 and 2 are accessible.
Note:1. The Pr. 77, Pr. 160 values may always be read independently of the user
group setting.
2. The Pr. 173 or Pr. 174 value read indicates the number of parameters
registered to group 1, and the Pr. 175 or Pr. 176 value read indicates the
number of parameters registered to group 2.
3. If "0" is set in the second digit of two-digit Pr. 160, it is not displayed.
However, "0" is displayed when it is set in the first digit only.
4. When "9999" is set in Pr. 174 or Pr. 176, the parameters registered to the
corresponding user group are batch-deleted.
