Parameter
● Encoder detection frequency search
When "2 or 12" is set in Pr. 162 under encoder feedback control, the motor starts at the
motor speed and in the rotation direction detected from the encoder at power restoration.
Encoder detection frequency search is performed regardless of the Pr. 162 setting under
vector control.
The Pr. 58 and Pr. 299 settings are invalid for encoder detection frequency search.

The output shut off timing differs according to the load condition.
NOTE
When encoder feedback control is invalid, setting "2 or 12" in Pr. 162 enables frequency
search.
● Restart operation at every start
When Pr. 162 = "10, 11 or 12", automatic restart operation is also performed every start, in addi-
tion to the automatic restart after instantaneous power failure. When Pr. 162 = "0" or "2",auto-
matic restart operation is performed at the first start after power supply-on, but the inverter starts
at the starting frequency at the second time or later.
