P.062 Option Port: Communication Loss Response

(continued)

If network communication is re-established, the drive will again follow the reference
and sequencing control inputs supplied by the network master. Note that if P.054 =
ON and the start and stop inputs are on (1), the drive will start.

Note that in this configuration, it may not always be possible to stop the drive over
the network.

If P.062 = 2

The drive gets its speed/torque reference from the terminal strip analog input and its
stop input from the terminal strip stop input. All other inputs are held at the last
values received from the network master.

This allows the network master to continue controlling the drive reference with a
direct-wired analog output to input, and to stop the drive with a direct-wired digital
output to input.

Note that if P.054 (Level Sense Start Enable) = OFF and the drive is stopped while
in this mode, it cannot be re-started until network communication is re-established
or the Control Source (P.000) is changed.

ATTENTION: if P.062 = 2 and P.054 (Level Sense Start Enable) = ON
and network communication is lost while the drive is running, the
terminal strip stop input will function as a STOP/RUN input. If the
terminal strip stop input is opened, the drive will stop. If the terminal
strip stop input is closed, the drive will re-start. Failure to observe this
precaution could result in severe bodily injury or loss of life.

Note that in this configuration, it might not always be possible to stop the drive over
the network.

The response to network communication loss is:

The drive continues to operate using the analog input from the Regulator board
terminal strip.

An entry is made into the drive's error log for each active-to-inactive transition of
the network communication status.

The front panel REMOTE LED blinks, indicating that the network is inactive.

If network communication is re-established, the drive will again follow the reference
and sequencing control inputs supplied by the network master. Note that if P.054 =
ON and the start and stop inputs are on (1), the drive will start.

ATTENTION: The drive is not equipped with a coast-stop pushbutton.
You must install a hardwired operator-accessible pushbutton that
provides a positive interrupt and shuts down the drive. See the
GV3000/SE AC Drive Hardware Reference, Installation, and
Troubleshooting 1-20 HP ` 230 VAC instruction manual (D2-3388) for
wiring information. Failure to observe this precaution could result in
bodily injury.
