No function
(NO FUNCTION) [0]
★ Bit 10 = 1: control word active
(BIT 10 = 1 >CTW ACTIVE) [1]
Bit 10 = 0: control word active

(BIT 10 = 0 >TIME OUT) [3]
Function:
According to the drive's standard
communications profile, control word and
speed reference will be ignored if bit 10 of the
control word is 0. Parameter 805 lets the user
change the function of bit 10. This is some
times necessary, as some masters set all bits
to 0 in various fault situations. In these cases,
it makes sense to change the function of bit
10 so that the TR1 is commanded to stop
(coast) when all bits are 0.
Description of Selections:
• No function. Bit 10 is ignored, i.e.,
control word and speed reference are
always valid.
• Bit 10 = 1 >CTW active. The control
word and speed reference are
ignored if bit 10 = 0.
• Bit 10 = 0 >CTW active. The control
word and speed reference are ignored
if bit 10 = 1. If all bits of the control
word are 0, the TR1 reaction will be
coasting.
• Bit 10 = 0 >time out. The time out
function selected in parameter 804 is
activated when bit 10 is 0.
Data Value:
Disable (DISABLE) [0]
★ Enable (ENABLE) [1]
This parameter determines LonWorks control
of the drive. When Enable is selected, drive
parameters 503 through 508 determine the
interaction between various LonWorks and
digital drive input commands. See the TR1
Series VFD Instruction Manual for details.
When this parameter is set to Store active
setup, LonWorks downloaded parameters are
written to EEPROM and stored. Store edit
setup stores the setup selected in parameter
970. Store all setups stores all setups in
parameter 970. When finished (appx. 15 sec.),
it automatically returns to No action. Any
parameters values written via the serial bus
with No action selected are lost when power
is removed from the drive. The function is only
activated with the TR1 in stop mode.
Data Value:
Disable (DISABLE) [0]
★ Enable (ENABLE) [1]
This parameter determines if LonWorks can
be used to access and edit drive parameters.
Data Value:
★ No action (NO ACTION) [0]
Store all setups
(STORE ALL SETUPS [1]

With Bit 10 = 0 >CTW active
selected, nviStartStop and
nviResetFault commands will not
function.
CAUTION
!
This parameter selects the setup being edited,
through either the drive control panel or
LonWorks. The drive may operate in one setup
while editing another. Active setup selects the
parameter being edited as the setup controlling
drive operation.
✭ Indicates factory default setting. Numbers in brackets [ ] represent selection as displayed on the serial bus.
