5-8 Selecting the Interruption Mode
This parameter is used to specify the interruption mode when the STOP command is
input.
The Inverter either decelerates or coasts to a stop according to the interruption mode
selection.

Set Values
Value Description
0 Frequency deceleration stop (See notes 1 and 2.)
1 Free running (See note 3.)
Note 1. The Inverter will decelerate to stop according to the setting in n17 for deceleration time 1 if any
of the n36 through n39 parameters for multi-function input is not set to 11 for acceleration/de-
celeration time selection. If any one of the n36 through n39 multi-function input parameters is
set to acceleration/deceleration time selection, the Inverter will decelerate to stop according
to the selected setting of deceleration time when the STOP command is input.
Note 2. If the RUN signal is input again during a deceleration stop, deceleration will be stopped at the
point of the input and acceleration will proceed at that frequency.
Note 3. Do not input a RUN signal during a free-running stop if the motor’s rotation speed is not suffi-
cient slowed. If a RUN signal is input under these conditions, a main circuit overvoltage (OV)
or overcurrent (OC) will be detected.
To restart a free-running motor, set a speed search command in one of the multi-function in-
puts 1 to 4 (n36 to n39), use the speed search to detect the speed of the free running motor,
and then accelerate smoothly.
