System Integration
Bit 08, Jog
Bit 08=1: Parameter 3-19 Jog Speed [RPM] determines the
output frequency.
Bit 09, Selection of ramp 1/2
Bit 09=0: Ramp 1 is active (parameter 3-41 Ramp 1 Ramp
3 3
Up Time to parameter 3-42 Ramp 1 Ramp Down Time).
Bit 09=1: Ramp 2 (parameter 3-51 Ramp 2 Ramp Up Time to
parameter 3-52 Ramp 2 Ramp Down Time) is active.
Bit 10, Data not valid/Data valid
Tells 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. Turn off the control word
if it should not be used when updating or reading
parameters.
Bit 11, Relay 01
Bit 11=0: Relay not activated.
Bit 11=1: Relay 01 activated if [36] Control word bit 11 is
selected in parameter 5-40 Function Relay.
Bit 12, Relay 04
Bit 12=0: Relay 04 is not activated.
Bit 12=1: Relay 04 is activated if [37] Control word bit 12 is
selected in parameter 5-40 Function Relay.
Bit 13/14, Selection of set-up
Use bits 13 and 14 to select from the 4 menu set-ups
according to Table 3.43.
Set-up
1
2
3
4
Table 3.43 Specification of Menu Set-ups
The function is only possible when [9] Multi Set-ups is
selected in parameter 0-10 Active Set-up.
Make a selection in parameter 8-55 Set-up Select to define
how bit 13/14 gates with the corresponding function on
the digital inputs.
Bit 15 Reverse
Bit 15=0: No reversing.
Bit 15=1: Reversing. In the default setting, reversing is set
to digital in parameter 8-54 Reversing Select. Bit 15 causes
reversing only when [1] Bus, [2] Logic AND or [3] Logic OR is
selected.

Explanation of the status bits
Bit 00, Control not ready/ready
Bit 00=0: The frequency converter trips.
Bit 00=1: The frequency converter controls are ready but
the power component does not necessarily receive any
power supply (in case of 24 V external supply to controls).
Bit 01, Drive ready
Bit 01=1: The frequency converter is ready for operation
but the coasting command is active via the digital inputs
or via serial communication.
Bit 02, Coasting stop
Bit 02=0: The frequency converter releases the motor.
Bit 02=1: The frequency converter starts the motor with a
start command.
Bit 03, No error/trip
Bit 03=0: The frequency converter is not in fault mode.
Bit 03=1: The frequency converter trips. To re-establish
operation, enter [Reset].
