The above parameters can be set when Pr. 160 User group read selection = "0". (Refer to page 188)
∗1
The setting value of "60" is available for Pr. 178 only.
∗2
The setting value of "61" is available for Pr. 179 only.
∗3
For the safety stop function model, this setting is active only during the communication operation. (
(1) Input terminal function assignment
Using Pr. 178 to Pr. 184, set the functions of the input terminals.
Refer to the following table and set the parameters:
