Restart operation with encoder detection frequency search (Pr.162 = "2
or 12")
• When "2 or 12" is set to Pr.162 by encoder feedback control, the inverter is restarted by the motor speed and direction of
rotation that were detected by the encoder at the power restoration.
• By encoder detection frequency search, the Pr.299 Rotation direction detection selection at restarting setting are
invalid.

NOTE
• If "2, 12" are set to Pr.162 when encoder feedback control is invalid, the automatic restart is with a frequency search (Pr.162
= "0, 10").
• In vector control, encoder detection frequency search is used regardless of the Pr.162 setting. The Pr.58 and Pr.299 settings
are invalid at this time.
• For the encoder feedback control, refer to
Restart at every start (Pr.162 ="10 to 13")
• When "10 to 13" is set in Pr.162, a restart operation is performed at each start and automatic restart after instantaneous
power failure (Pr.57 start after the reset time has elapsed). When "0 (initial value) to 3" is set in Pr.162, a restart operation
is performed at the first start after a power-ON, and from the second power-ON onwards, a start from the starting frequency
is performed.
Automatic restart operation of MRS (X10) signal
• The restart operation after restoration from output shutoff by the MRS (X10) signal is as shown in the table below according
to the Pr.30 setting.
