Bit 03 = '0': The frequency converter immediately "lets go" of the motor, (the output transistors are "shut off") and it coasts to a standstill. Bit 03 = '1': The frequency

converter starts the motor if the other starting conditions are met.

Make a selection in par. O-50 Coasting Select to define how Bit 03 gates with the corresponding function on a digital input.

Bit 04, Quick stop:

Bit 04 = '0': Makes the motor speed decel to stop (set in par. C-23 Quick Stop Decel Time).

Bit 05, Hold output frequency

Bit 05 = '0': The present output frequency (in Hz) freezes. Change the frozen output frequency only by means of the digital inputs (par. E-01 Terminal 18 Digital

Input to par. E-06 Terminal 33 Digital Input) programmed to Speed up and Slow 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 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 and makes the motor speed decel to stop via the selected decel parameter. Bit 06 = '1': Permits the frequency converter to start the

motor, if the other starting conditions are met.

Make a selection in par. O-53 Start Select to define how Bit 06 Ramp stop/start gates with the corresponding function on a digital input.

Bit 07, Reset: Bit 07 = '0': No reset. Bit 07 = '1': Resets 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': The output frequency is determined by par. C-21 Jog Speed [RPM].

Bit 09, Selection of ramp 1/2:

Bit 09 = "0": Ramp 1 is active (par. F-07 Accel Time 1 to par. F-08 Decel Time 1). Bit 09 = "1": Ramp 2 (par. E-10 Accel Time 2 to par. E-11 Decel Time 2) is active.

Bit 10, Data not valid/Data valid:

Tell the frequency converter whether to use or ignore the control word. Bit 10 = '0': The control word is ignored. Bit 10 = '1': The control word is used. This function

is relevant because the telegram always contains the control word, regardless of the telegram type. Thus, you can turn off the control word if you do not want to

use it when updating or reading parameters.

Bit 11, Relay 01:

Bit 11 = "0": Relay not activated. Bit 11 = "1": Relay 01 activated provided that Control word bit 11 is chosen in par. E-24 Function Relay.

Bit 12, Relay 04:

Bit 12 = "0": Relay 04 is not activated. Bit 12 = "1": Relay 04 is activated provided that Control word bit 12 is chosen in par. E-24 Function Relay.
