3-14 Preset Relative Reference
Range: Function:
added to the actual reference (X+X*Y/100)
to give the resultant actual reference.
3-15 Reference Resource 1
Option: Function:
NOTICE!
This parameter cannot be adjusted
while the motor is running.
Select the reference input to be used for

signal.parameter 3-15 Reference Resource 1,
parameter 3-16 Reference Resource 2 and
parameter 3-17 Reference Resource 3 dene
up to three dierent reference signals. The
sum of these reference signals denes the
actual reference.

3-18 Relative Scaling Reference Resource
Option: Function:
Select a variable value to be added to the xed
value (dened in 3-14 Preset Relative Reference).
The sum of the xed and variable values is
multiplied with the actual reference. This
product is then added to the actual reference
(X+X*Y/100) to give the resultant actual
reference
Same options as parameter 3-15 Reference

[ 0 -
par. 4-13
RPM]
Enter a value for the jog speed n
JOG
, which
is a xed output speed. The frequency
converter runs at this speed when the jog
function is activated. The maximum limit is
dened in parameter 4-13 Motor Speed High
Limit [RPM].
See also parameter 3-80 Jog Ramp Time.
3-40 Ramp 1 Type
Option: Function:
Select the ramp type, depending on requirements
for acceleration/deceleration. A linear ramp will give
constant acceleration during ramping.
[0] * Linear
3-41 Ramp Up Time Running (sec)
Range: Function:
5 s min.* [Comp
dependent]
Enter the ramp-up time, i.e. the
acceleration time to reach the
system required motor speed.
