Digital and Analog Inputs and Outputs
Description:
It defines the motor stop mode when the inverter receives the "Stop" command. The
describes the options of this parameter.
P0229
0 = Ramp to Stop
1 = Coast to Stop
2 = Fast Stop
3 = By Ramp with Iq* reset
4 = Fast Stop with Iq* reset
NOTE!
When the control modes V/f or VVW are selected, the use of the option 2 (Fast Stop) is not
recommended.
NOTE!
When the Coast to Stop, stop mode, is programmed and the Flying-Start function is not enabled, then
start the motor again only if it is standing still.
NOTE!
Options 3 and 4 will operate only with P0202 = 4 or P0202 = 6.
The difference in behavior, compared to the options 0 and 2, is in the torque current reference (Iq*)
reset. This reset occurs during the inverter state transition from Run to Ready, after executing a Stop
command. The purpose of the options 3 and 4 is to avoid that a high current reference value is stored
in the speed regulator when, for instance, using a mechanical brake to stop the motor shaft before
its speed is null.

Table 13.12 - Stop mode selection
The inverter will apply the ramp programmed in P0101 and/or P0103
The motor will run free until stopping
The inverter will apply a null ramp (time = 0.0 second), in order to stop the motor in the shortest possible time
The inverter will apply the deceleration ramp programmed in P0101 or P0103, and will reset the torque
current reference
The inverter will apply a null ramp (time = 0.0 second), in order to stop the motor in the shortest possible
time, and will reset the torque current reference
