System Integration
NOTICE!
The selection in 8-50 Coasting Select determines how bit
03 is linked with the corresponding function of the
3 3
digital inputs.
Bit 04, Quick stop/Ramp
Quick stop using the ramp time of 3-81 Quick Stop Ramp
Time.
When bit 04=0, a quick stop occurs.
When bit 04=1, the adjustable frequency drive can start if
the other start conditions are satisfied.
NOTICE!
The selection in 8-51 Quick Stop Select determines how
bit 04 is linked with the corresponding function of the
digital inputs.
Bit 05, Hold frequency output/Use ramp
When bit 05=0, the current output frequency is being
maintained even if the reference value is modified.
When bit 05=1, the adjustable frequency drive can perform
its regulating function again; operation occurs according to
the respective reference value.
Bit 06, Ramp stop/Start
Normal ramp stop using the ramp times of the actual
ramp as selected. In addition, activation of the output relay
01 or 04 if the output frequency is 0 Hz and if relay 123
has been selected in 5-40 Function Relay.
Bit 06=0 leads to a stop.
When bit 06=1, the adjustable frequency drive can start if
the other start conditions are fulfilled.
NOTICE!
The selection in 8-53 Start Select determines how bit 06
is linked with the corresponding function of the digital
inputs.
Bit 07, No function/Reset
Reset after switching off.
Acknowledges event in fault buffer.
When bit 07=0, no reset occurs.
When there is a slope change of bit 07 to 1, a reset occurs
after switching off.
Bit 08, Jog 1 Off/On
Activation of the pre-programmed speed in 8-90 Bus Jog 1
Speed. JOG 1 is only possible if bit 04=0 and bit 00-03=1.
Bit 09, Jog 2 Off/On
Activation of the pre-programmed speed in 8-91 Bus Jog 2
Speed. Jog 2 is only possible if bit 04=0 and bit 00-03=1.
Bit 10, Data invalid/valid
Is used to tell the adjustable frequency drive 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. This function
is relevant because the control word is always contained in
the message, regardless of which type of message is used.
It is possible to turn off the control word if it should not
be used for updating or reading parameters.
Bit 11, No function/Slow-down
Is used to reduce the speed reference value by the amount
given in 3-12 Catch up/slow-down Value.
When bit 11=0, no modification of the reference value
occurs.
When bit 11=1, the reference value is reduced.
Bit 12, No function/Catch up
Is used to increase the speed reference value by the
amount given in 3-12 Catch up/slow-down Value.
When bit 12=0, no modification of the reference value
occurs.
When bit 12=1, the reference value is increased.
If both slowing down and accelerating are activated (bit 11
and 12=1), slowing down has priority, that is, the speed
reference value is reduced.
Bits 13/14, Set-up selection
Bits 13 and 14 are used to select between the four
parameter set-ups according to Table 3.48.
The function is only possible if [9] Multi Set-up has been
selected in 0-10 Active Set-up. The selection in 8-55 Set-up
Select determines how bits 13 and 14 are linked with the
corresponding function of the digital inputs. Changing set-
up while running is only possible if the set-ups have been
linked in 0-12 This Set-up Linked to.
Table 3.48 Set-up Selection
Bit 15, No function/Reverse
Bit 15=0 causes no reversing.
Bit 15=1 causes reversing.
NOTICE!
In the factory settings, reversing is set to digital in
8-54 Reverse Select.
NOTICE!
Bit 15 causes reversing only when Ser. communication,
Logic or or Logic and is selected.
