Function:
Select the reference input to be used
for the first reference signal.
Parameter 3-15 Reference 1 Source
parameter 3-16 Reference 2 Source
, and
parameter 3-17 Reference 3 Source
define up to 3 different reference
signals. The sum of these reference
signals defines the actual reference.

3-18 Relative Scaling Reference Resource
Option:
Function:
NOTICE
This parameter cannot be adjusted
while the motor is running.
Select a variable value to be added to the
fixed value (defined in
parameter 3-14 Preset Relative Reference
).
The sum of the fixed and variable values
(labelled Y in
) is multiplied
by the actual reference (labelled X in
). This product is then
added to the actual reference (X+X*Y/100)
to give the resulting actual reference.

Option:
Function:
Select the ramp type, depending on
requirements for acceleration/deceleration. A
linear ramp gives constant acceleration during
ramping. A sine 2 ramp gives non-linear
acceleration.
