Explanation of Control Bits
Bits 00/01
Bits 00 and 01 are used to choose between the four reference values, which
are pre-programmed in par. C-05 Multi-step Frequency 1 - 8 according to the
following table:
Programmed Parameter
ref. value
1 C-05 [0]
2 C-05 [1]
3 C-05 [2]
4 C-05 [3]

NB!
In par. O-56 Preset Reference Select 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 par. B-01 DC Brake Current and par. B-02 DC Braking Time. Bit 02 = '1' leads
to ramping, par. F-07 Accel Time 1
Bit 03, Coasting:
Bit 03 = '0' causes the frequency converter to immediately "let go" of the motor
(the output transistors are "shut off"), so that it coasts to a standstill.
Bit 03 = '1' enables the frequency converter to start the motor if the other
starting conditions have been fulfilled.
NB!
In par. O-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 deceled to stop via
par. C-23 Quick Stop Decel 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 by means of the digital inputs
(par. E-01 Terminal 18 Digital Input to par. E-06 Terminal 33 Digital Input) pro-
grammed to Speed up and Speed down.
NB!
If Freeze output is active, the frequency converter can only be stopped by
the following:
• Bit 03 Coasting stop
• Bit 02 DC braking
• Digital input (par. E-01 Terminal 18 Digital Input to par. E-06 Ter-
minal 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 deceled to stop via the
selected decel parameter. Bit 06 = '1' permits the frequency converter to start
the motor, if the other starting conditions have been fulfilled.
NB!
In par. O-53 Start Select Start select a selection is made to define how Bit
06 Ramp stop/start gates with the corresponding function on a digital input.
