The jog speed is a xed output
speed at which the frequency
converter is running when the jog
function is activated.
See also parameter 3-19 Jog Speed
[RPM] and parameter 3-80 Jog Ramp
Time.
3-13 Reference Site
Option: Function:
Select which reference site to
activate.
[0] * Linked to
Hand / Auto
Use local reference when in hand-
on mode, or remote reference
when in auto-on mode.
[1] Remote Use remote reference in both hand-
on mode and auto-on mode.
[2] Local Use local reference in both hand-on
mode and auto-on mode.
NOTICE
When set to [2] Local, the
frequency converter starts with
this setting again after a
power-down.
[3] Linked to H/A
MCO
Select this option to enable the
FFACC factor in
parameter 32-66 Acceleration Feed-
Forward. Enabling FFACC reduces
jitter and makes the transmission
from the motion controller to the
control card of the frequency
converter faster. This leads to faster
response times for dynamic
applications and position control.

3-14 Preset Relative Reference
Range: Function:
0 %* [-100 -
100 %]
The actual reference, X, is increased
or decreased with the percentage Y,
set in parameter 3-14 Preset Relative
Reference.
This results in the actual reference
Z. Actual reference (X) is the sum of
the inputs selected in:
