 Setting for the automatic restart after instantaneous power failure
operation (Pr.162)
• The Pr.162 settings and the instantaneous power failure automatic restart operation under each operation mode are as
shown below.

 Restart operation with frequency search (Pr.162 = "0, 2, 3, 10, 12, 13,
1000, 1002, 1003, 1010, 1012, or 1013", Pr.299)
• When Pr.162 = "0 (initial value), 2, 3, 10, 12, 13, 1000, 1002, 1003, 1010, 1012, or 1013", the motor speed is detected at
a power restoration so that the motor can re-start smoothly.
• The encoder also detects the rotation direction so that the motor can re-start smoothly even during the reverse rotation.
• Whether or not to detect the rotation direction can be selected by Pr.299 Rotation direction detection selection at
restarting. If the motor capacity is different from the inverter capacity, set Pr.299 = "0 (no rotation direction detection)".
• When the rotation direction is detected, the following operation is performed according to the Pr.78 Reverse rotation
prevention selection setting.
