NOTE
• The automatic restart after instantaneous power failure function and orientation function do not operate when brake
sequence is selected.
• To use this function, set the acceleration/deceleration time to 1 s or higher.
• Changing the terminal assignment using
Pr.178 to Pr.189 (Input terminal function selection) and Pr.190 to Pr.196
(Output terminal function selection) may affect the other functions. Set parameters after confirming the function of each
terminal.
