Bit 00, Switch OFF/ON
:
Bit 00= "0" execute transition 2, 6 or 8
Bit 00 = "1" execute transition 3
Bit 01, Disable/Enable Voltage:
Bit 01= "0" execute transition 9, 10 or 12
Bit 01 = "1" = Enable Voltage
Bit 02, Quick stop/Run:
Bit 02= "0" execute transition 7, 10 or 11.
Bit 02 = "1" = Quick stop not active.
Bit 03, Disable/enable Operation:
Bit 03= "0" execute transition 5.
Bit 03 = "1" = Enable operation
Bit 04, Quick-stop/ramp:
Bit 04= "0" execute transition 7 or 11, Quick stop
Bit 04 = "1" = Enable ramp.
Bit 05, Freeze output frequency/ramp enable:
Bit 05 = "0" means that the given output frequency is
maintained even if the reference is changed.
Bit 05 = "1" means that the frequency converter is
again able to regulate, and the given reference is
followed.
Bit 06, Ramp stop/start:
Bit06= "0" The VLT controls the motor down to
stop.
Bit 01 = "1" = Start command to the VLT is given
Bit 07, No function/reset
Reset of trip. Bit 07 = "0" means that there is no
reset. Bit 07 = "1" means that a trip is reset.
Bit 08, 09 and 10 :
Drivecom reserved.
Bit 11, Jog 1 OFF/ON:
Activation of pre-programmed speed in
parameter 509 (Bus JOG 1). JOG 1 is only
possible when Bit 04 = "0" and bit 00-03 = "1".
Bit 12,:
Danfoss reserved.
Bits 13/14, Choice of Setup:
Bits 13 and 14 are used for choosing among the
four menu Setups in accordance with the

Bit 15, No function/reversing:
Reversing of the direction of rotation of the motor.
Bit 15 = "0" leads to no reversing, bit 15 = "1"
leads to reversing.
Please note that, in the factory setting, reversing
has been chosen as digital in parameter 506,
which means that bit 15 will only lead to reversing
if
bus, logic or
or
logic and
(however,
logic and
only together with terminal 19) has been
selected.
NB!
Unless otherwise mentioned, the control
word bit is combined (gated) with the
corresponding function on the digital
inputs as a logical "or" function.
