Function:
Enter the maximum acceptable value for the remote reference. The Maximum Reference value and
unit matches the configuration choice made in par.1-00
ence/Feedback Unit
, respectively.

Function:
Enter the ramp-up time, i.e. the acceleration time from 0 RPM to par.1-25
Choose a ramp-up time such that the output current does not exceed the current limit in
par. 4-18 Current Limit during ramping. See ramp-down time in par.3-42

Function:
Enter the ramp-down time, i.e. the deceleration time from par.1-25
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 par. 4-18 Current Limit . See ramp-up time in par.3-41

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.
Use local reference in both Hand mode and Auto mode.
NB!
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 par. 2-01

DC Braking Time
par. 2-02 is different from 0. Logic '0' => DC braking.
