Bit 06, Ramp stop/start:
Bit 06 = ’0’ causes a stop, in which the motor
speed is ramped down to stop via the selected
ramp down
parameter.
Bit 06 = ’1’ permits the frequency converter to
start the motor, if the other starting conditions
have been fulfilled.
N.B.:
In parameter 8-53
Start select
a selection
is made to define how Bit 06 Ramp
stop/start gates with the corresponding
function on a digital input.
Bit 07, Reset:
Bit 07 = ’0’ does not cause a reset.
Bit 07 = ’1’ causes the reset of a trip. Reset is
activated on the signal’s leading edge, i.e.
when changing from logic ’0’ to logic ’1’.
Bit 08, Jog:
Bit 08 = ’1’ causes the output frequency to be
determined by parameter 3-19
Jog speed.
Bit 09, Selection of ramp 1/2:
Bit 09 = "0" means that ramp 1 is active
(parameters 3-40 to 3-47). Bit 09 = "1" means
that ramp 2 (parameters 3-50 to 3-57) is
active.
Bit 10, Data not valid/Data valid:
Is used to tell the frequency converter whether
the control word is to be used or ignored. Bit
10 = ’0’ causes the control word to be ignored,
Bit 10 = ’1’ causes the control word to be used.
This function is relevant, because the control
word is always contained in the telegram,
regardless of which type of telegram is used,
i.e. it is possible to turn off the control word if
you do not wish to use it in connection with
updating or reading parameters.
Bit 11, Relay 01:
Bit 11 = "0" Relay not activated.
Bit 11 = "1" Relay 01 activated, provided
Control word bit 11
has been chosen in
parameter 5-40
Function relay
.
Bit 12, Relay 04:
Bit 12 = "0" Relay 04 has not been activated.
Bit 12 = "1" Relay 04 has been activated,
provided
Control word bit 12
has been chosen
in parameter 5-40
Function relay
.
Bit 13/14, Selection of set-up:
Bits 13 and 14 are used to choose from the
four menu set-ups according to the following
table:
Set-up
Bit 14
Bit 13
1 0
0
2 0
1
3 1
0
4 1
1
The function is only possible when
Multi-Set-
ups
is selected in parameter 0-10
Active Set-
up
.
N.B.:
In parameter 8-55
Set-up select
a
selection is made to define how Bit 13/14
gates with the corresponding function on the
digital inputs.
Bit 15 Reverse:
Bit 15 = ’0’ causes no reversing.
Bit 15 = ’1’ causes reversing.
Note: In the factory setting reversing is set to
digital
in parameter 8-54
Reversing select
.
Bit 15 causes reversing only when
Ser.
