Rockwell Automation GV3000/SE AC Drive ControlNet Network Communication Board, M/N 2CN3000 - Manual (Page 59)

Setting Up the GV3000/SE Drive 3-5
When P.062 = 3 (Use terminal strip control), the drive uses the terminal strip inputs for
start, stop, reset, and run/jog when loss of communication is detected. Note that if
P.054 (Level Sense Start Enable) = ON and the start and stop inputs are on (1), the
drive may start.
Depending on how P.007 and P.008 are configured, the drive may also use the
terminal strip inputs for forward/reverse, ramp 1/2, torque/speed, MOP up, MOP down,
and preset speed selection. The only terminal strip signal that cannot be used is
rem/loc. The function loss digital input remains active at all times.
While communication is lost, the speed reference is the analog input, the MOP, or one
of the preset speeds, depending on the value of P.008 and the configured digital
inputs. When 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 network start and stop commands are on (1), the drive will start.
Important: The drive regulator may become operational before the ControlNet
network becomes active (sending and receiving start/stop commands). If
this occurs, the drive will start on power up when P.062 = 3 and all of the
following conditions are true:
• P.000 (Control Source) = OP
• P.054 (Level Sense Enable) = ON
• The terminal strip stop input is closed
• The terminal strip function loss input is closed
• The terminal strip start signal is closed and maintained.
When communication is established and the network becomes active, the
drive will receive its start/stop commands from the network.
When P.062 = 4 and an nCL or F62 error occurs, then the drive will operate as
described above for P.062 = 3.
!
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.
!
ATTENTION: F62 indicates a watchdog timeout on the ControlNet
Interface Module. This normally results in drive shutdown with the F62
fatal fault annunciated. The F62 is typically a result of faulty interface
module hardware. It can also occur as a result of excess noise generated
during an event that severs the control net cable. This mode of operation
should be used only in applications where motor stoppage would result
in damage to costly equipment. Failure to observe this precaution could
result in damage to equipment.
