NOTICE
In
parameter 8-56 Preset Reference Select
, a selection is
made to define how bit 00/01 gates with the
corresponding function on the digital inputs.
Bit 02, DC brake
Bit 02 = 0: Leads to DC braking and stop. Braking current
and duration are set in
parameter 2-01 DC Brake Current
and
parameter 2-02 DC Braking Time
.
Bit 02 = 1: Leads to ramping.
Bit 03, Coasting
Bit 03 = 0: Causes the frequency converter to immediately
release the motor (the output transistors are disabled), and
coasts to a standstill.
Bit 03 = 1: Enables the frequency converter to start the
motor if the other starting conditions are fulfilled.
NOTICE
In
parameter 8-50 Coasting Select
, a selection is made to
define how bit 03 gates with the corresponding function
on a digital input.
Bit 04, Quick stop
Bit 04 = 0: Causes a stop, in which the motor speed is
ramped down to stop via
parameter 3-81 Quick Stop Ramp
Time
.
Bit 05, Hold output frequency
Bit 05 = 0: Causes the present output frequency (in Hz) to
freeze. The frozen output frequency can then be changed
only with the digital inputs (
parameter 5-10 Terminal 18
Digital Input
to
parameter 5-15 Terminal 33 Digital Input
)
programmed to speed up and speed down.
NOTICE
If hold output is active, only the following can stop the
frequency converter:
•
Bit 03 coasting stop.
•
Bit 02 DC braking.
•
Digital input (
parameter 5-10 Terminal 18 Digital
Input
to
parameter 5-15 Terminal 33 Digital
Input
) programmed to DC braking, coasting
stop, or reset and coasting stop.
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: Allows the frequency converter to start the
motor, if the other starting conditions are fulfilled.
NOTICE
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: Resets a trip. Reset is activated on the leading
edge of the signal, that is, when changing from logic 0 to
logic 1.
Bit 08, Jog
Bit 08 = 1: The frequency converter ramps up/ramps down
according to the setting in
parameter 3-19 Jog Speed [RPM]
.
Bit 09, Selection of ramp 1/2
Bit 09 = 0: Ramp 1 is active (
parameter 3-40 Ramp 1 Type
to
parameter 3-47 Ramp 1 S-ramp Ratio at Decel. Start
).
Bit 09 = 1: Ramp 2 is active (
parameter 3-50 Ramp 2 Type
to
parameter 3-57 Ramp 2 S-ramp Ratio at Decel. Start
).
Bit 10, Data not valid/Data valid
Tells the frequency converter whether to use or to ignore
the control word.
Bit 10 = 0: Ignores the control word.
Bit 10 = 1: Uses the control word to be used. This function
is relevant, because the control word is always contained
in the telegram, regardless of the type of telegram. It is
possible to turn off the control word if you do not wish to
use it with updating or reading parameters.
Bit 11, Relay 01
Bit 11 = 0: Relay not activated.
Bit 11 = 1: Relay 01 activated, provided
[36] control word
bit 11
is selected in
parameter 5-40 Function Relay
.
Bit 12, Relay 04
Bit 12 = 0: Relay 04 is not activated.
Bit 12 = 1: Relay 04 is activated, provided
[37] control word
bit 12
is selected in
parameter 5-40 Function Relay
.
Bit 13/14, Selection of set-up

NOTICE
In
parameter 8-55 Set-up Select
, a selection is made to
define how bits 13/14 gate with the corresponding
function on the digital inputs.
Bit 15 Reverse
Bit 15 = 0: No reversing.
Bit 15 = 1: Reversing.
