Power failure-time deceleration-to-stop function (Pr. 261)

When a power failure or under voltage occurs, the inverter can be decelerated to a stop or can
be decelerated and re-accelerated to the set frequency.

selection
The above parameter can be set when Pr. 160 "User group read selection" = 0.
Parameter setting
When Pr. 261 is set to "1" or "2", the inverter decelerates to a stop if an undervoltage or power
failure occurs.
Operation outline of deceleration to stop at power failure
When undervoltage or power failure has occurred, the output frequency is decreased and con-
trolled so that the converter circuit (DC bus) voltage is constant and decreased to 0Hz to stop.

Initial Setting
Description
Value Range
Coasting to stop when under voltage or
0 power failure occurs, the inverter output
is shut off.
When under voltage or a power failure
1 occurs, the inverter can be decelerated to
0
a stop.
When under voltage or a power failure
occurs, the inverter can be decelerated to
2 a stop.
If power is restored during a power fail-
ure, the inverter accelerates again.
