4.3. Parameter Lists

Changes during operation
"TRUE" means that the parameter can be changed while the frequency converter is in operation
and "FALSE" means that the it must be stopped before a change can be made.
4-Set-up
'All set-up': the parameters can be set individually in each of the four set-ups, i.e. one single
parameter can have four different data values.
'1 set-up': data value will be the same in all set-ups.
Conversion index
This number refers to a conversion figure used when writing or reading to and from the frequency
converter.

Function:
[0.01 - 3600.00 s] Enter the ramp-up time, i.e. the acceleration time from 0 RPM
to the rated motor speed n
time such that the output current does not exceed the current
limit in par. 4-18 during ramping. The value 0.00 corresponds
to 0.01 sec. in speed mode. See ramp-down time in par. 3-42.

Function:
[0.01 - 3600.00 s] Enter the ramp-down time, i.e. the deceleration time from the
rated motor speed n
down time such that no over-voltage arises in the inverter due
to regenerative operation of the motor, and such that the gen-
erated current does not exceed the current limit set in par. 4-18.
The value 0.00 corresponds to 0.01 s in speed mode. See ramp-
up time in par. 3-41.
