Function:
Select the reference input to be used
for the third reference signal.
3-15 Reference 1 Source, 3-16 Reference
2 Source and 3-17 Reference 3 Source
define up to three different reference
signals. The sum of these reference
signals defines the actual reference.
Function:
[ 0 - par. Enter a value for the jog speed n
which is a fixed output speed. The
adjustable frequency drive runs at this
speed when the jog function is
activated. The maximum limit is defined
in 4-13 Motor Speed High Limit [RPM].

Function:
[ 1.00 - Enter the ramp-up time, i.e., the
3600 s] 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.

Function:
[ 1.00 - Enter the ramp-down time, i.e., the
3600 s] deceleration time from 1-25 Motor
Nominal Speed to 0 RPM. Choose a ramp-
down time such that no overvoltage
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.
