(1) Setting start/stop function
The motor will run when the frequency (speed) setting is higher than the C20-0 setting
value, and will stop when lower.
Starting and stopping with the setter is possible with this function.
(2) Start interlock
If the frequency (speed) setting value is larger than C20-2 when the run command
(RUN X) is ON, the motor will not start.
(Note) The setting start/stop and start interlock functions cannot be used
simultaneously. Thus, set C20-0 or C20-2 to 0.

(3) Run delay timer
The motor will be delayed from the run command (RUN X) by the time set in C20-3.
This is used for synchronisation with peripheral machines such as mechanical brakes.
The run delay timer will not function in the jogging or local modes.
(Note 1)
Set the parameter setting values to 0 when not using (1),, (2) or (3).
(Note 2)
The (1), (2) and (3) functions will not function during jogging run.
(Note 3)
The (3) function will not function during the local mode.
(Note 4)
When interlock is applied on (1), (2) or (3), the FWD or REV LED will flicker.
