4. Setting the Start/Stop source:
In case the 3-Wire Start/Stop should operate in local mode, P0224 must be set to 4 = SoftPLC. When the
3-Wire Start/Stop application should operate in remote mode, P0227 must be set to 4 = SoftPLC.
NOTE!
For the proper implementation of the 3-Wire Start/Stop application, it is essential to check if the inverter
is properly configured to run the motor at the desired speed. Thus, check the following settings:
„
Torque boosts (P0136 and P0137) and slip compensation (P0138) if in V/f control mode.
„
Run the auto tuning if in vector mode.
„
Acceleration and deceleration ramps (P0100 to P0103) and current limiting (P0135 for V/f and
VVW control, or P0169/P0170 for vector control).
NOTE!
In case the 3-Wire Start/Stop application has been selected to operate in local mode and DI1 (P0263)
has been selected to start or stop command, the inverter can go to the “configuration (CONF)” state
and it will be necessary to change the default set of parameter P0227.
Operation setup
Check the status of the 3-Wire Start/Stop application in the P1000 parameter. The 3-Wire Start/Stop will be in
operation if P1000 value is 4. If P1000 value is 3, the 3-Wire Start/Stop application is stopped and it is necessary
to change the command value of the SoftPLC at parameter P1001 to 1 (run application). Any value other than 3 or
4 indicates that the applicative cannot go into operation. For more details, refer to the CFW700 SoftPLC manual.
