5 How to Control
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
quency converter to start the motor, if the other starting conditions have
been fulfilled.
NB!
In par. 8-53
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
5 leading edge of the signal, i.e. when changing from logic '0' to logic '1'.
Bit 08, Jog:
Bit 08 = '1' causes the output frequency to be determined by
par. 3-19 Jog Speed [RPM]
Bit 09, Selection of ramp 1/2:
Bit 09 = '0' means that ramp 1 is active (par. 3-40
par. 3-47 Ramp 1 S-ramp Ratio at Decel. Start
Ramp 2 Type
ramp 2 (par. 3-50
Decel. Start
) is active.
Bit 10, Data not valid/Data valid:
This bit tells the frequency converter whether the control word is to be
used or ignored. Bit 10 = '0' causes the control word to be ignored, Bit
10 = '1' causes the control word to be used. The control word is always
contained in the telegram, regardless of which type of telegram is used,
so this function is useful for 'turning off' the control word when not re-
quired for updating or reading parameters.

Bit 12 = '0' Relay 02 has not been activated. Bit 12 = '1' Relay 02 has

Bit 13/14, Selection of set-up:
Bits 13 and 14 are used to select one of four menu set-ups according to
the following table:

Bit 15 Reverse:
Bit 15 = '0' causes no reversing. Bit 15 = '1' causes reversing. Note: In
the factory setting reversing is set to
