➃ The “Run” input must be a maintained input. After a stop
command, either a “Run Forward” or “Run Reverse” input must
be toggled to start the controller.
➄ When this input is in an open state, P69 – [Accel Time 2] and
P70 – [Decel Time 2] are active.
➅ When this input in in an open state, all power is removed from
the motor and it will “coast to rest”.
➆ When this input is in an open state the Frequency source is
always from the terminal block regardless of the setting of
P59 – [Frequency Select].
Important: In modes 4 through 6, Terminal
TB3-8 is also used to clear faults. See Figure 2.12
for details.
Important: The system programmer is
responsible for returning terminal TB3-8 to its
original state if necessary.
