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.

NB!

Make a selection in par. 8-50

Bit 04, Quick stop:

Bit 04 = '0': Makes the motor speed ramp down to stop (set in par. 3-81

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. 5-10 to 5-15)

programmed to

and

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. 5-10 to 5-15) programmed to

Bit 06, Ramp stop/start:

Bit 06 = '0': Causes a stop and makes the motor speed ramp down to stop via the selected ramp down par. Bit 06 = '1': Permits the frequency converter

to start the motor, if the other starting conditions are met.

NB!

Make a selection in par. 8-53

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. 3-19

Bit 09, Selection of ramp 1/2:

Bit 09 = "0": Ramp 1 is active (par. 3-40 to 3-47). Bit 09 = "1": Ramp 2 (par. 3-50 to 3-57) 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

Bit 12, Relay 04:

Bit 12 = "0": Relay 04 is not activated. Bit 12 = "1": Relay 04 is activated provided that
