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.

The input signal terminals differ by the settings
of Pr.178 to Pr.189.
The output signal terminals differ by the settings
of Pr.190 to Pr.196.
Be careful of the permissible current of the built-in
transistors on the inverter. (24 VDC 0.1 A)
