Function:
[par. 3-02 - Enter the maximum
999999.999 acceptable value for the
ReferenceFeed- remote reference. The
backUnit] Maximum Reference value
and unit matches the
configuration choice made
in 1-00 Configuration Mode
and 20-12 Reference/
Feedback Unit, respec-
tively.
NOTE
If operating with
1-00 Configuration
Mode set for Closed
Loop [3],
20-14 Maximum
Reference/Feedb. must
be used.
Function:
Enter the ramp-up time, i.e. the acceleration time
from 0 RPM to 1-25 Motor Nominal Speed. Choose
a ramp-up time such that the output current
does not exceed the current limit in 4-18 Current
Limit during ramping. See ramp-down time in
3-42 Ramp 1 Ramp Down Time.

ref rpm
Function:
Enter the ramp-down time, i.e. the deceleration
time from 1-25 Motor Nominal Speed to 0 RPM.
Choose a ramp-down time such that no over-
voltage arises in the inverter due to regenerative
operation of the motor, and such that the
generated current does not exceed the current
limit set in 4-18 Current Limit. See ramp-up time
in 3-41 Ramp 1 Ramp Up Time.

Function:
Select which reference site to activate.
Use local reference when in Hand mode; or
remote reference when in Auto mode.
Use remote reference in both Hand mode
and Auto mode.

MG.11.L4.02 - ADAP-KOOL Drive
Function:
Use local reference in both Hand mode and
Auto mode.
NOTE
When set to Local [2], the frequency
converter will start with this setting
again following a 'power down'.
Function:
No reaction to signals transmitted to
terminal.
Resets frequency converter after a TRIP/
ALARM. Not all alarms can be reset.
Leaves motor in free mode. Logic '0' =>
coasting stop.
(Default Digital input 27): Coasting stop,
inverted input (NC).
Reset and coasting stop Inverted input
(NC).
Leaves motor in free mode and resets the
frequency converter. Logic '0' => coasting
stop and reset.
Inverted input for DC braking (NC).
Stops motor by energizing it with a DC
current for a certain time period. See
2-01 DC Brake Current to 2-03 DC Brake Cut
In Speed [RPM]. The function is only active
when the value in 2-02 DC Braking Time is
different from 0. Logic '0' => DC braking.
Stop Inverted function. Generates a stop
function when the selected terminal goes
from logical level '1' to '0'. The stop is
performed according to the selected ramp
time (3-42 Ramp 1 Ramp Down Time,
3-52 Ramp 2 Ramp Down Time, par. 3-62,
par. 3-72).
NOTE
When the frequency converter is at
the torque limit and has received a
stop command, it may not stop by
itself. To ensure that the frequency
converter stops, configure a digital
output to Torque limit & stop [27] and
connect this digital output to a digital
input that is configured as coast.
Same function as Coasting stop, inverse,
but External Interlock generates the alarm
message 'external fault' on the display
when the terminal which is programmed
for Coast Inverse is logic '0'. The alarm
message will also be active via digital
outputs and relay outputs, if programmed
