SPEED CONTROL OF INTERMEDIATE SHAFTS
6
Line speed command input setting
Set Pr.361 to select an interface for the line speed command value input.
∗1 To perform Vector control, install the Vector control compatible option.
∗2 The input specification in the initial setting is indicated. (Refer to page 43 .)
The following table shows a setting example.
NOTE
• The information on various settings about the line speed is provided in the chapter for the dancer feedback speed control.
Refer to page 58 .
