3-11 Jog Speed [Hz]
Range: Function:
Size [ 0 - par. The jog speed is a fixed output speed at
related 4-14 Hz] which the frequency converter is
*
running, when the jog function is
activated.
See also parameter 3-80 Jog/Homing
Ramp Time.
3-12 Catch up/slow Down Value
Range: Function:
0 % [0 - Enter a percentage (relative) value to be either
*
100 %] added to or deducted from the actual reference
for catch up or slow down. If catch up is selected
via 1 of the digital inputs (parameter 5-10 Terminal
18 Digital Input to parameter 5-15 Terminal 33
Digital Input), the percentage (relative) value is
added to the total reference. If slow down is
selected via 1 of the digital inputs
(parameter 5-10 Terminal 18 Digital Input to
parameter 5-15 Terminal 33 Digital Input), the
percentage (relative) value is deducted from the
total reference. Obtain extended functionality with

3-12 Catch up/slow Down Value
Range: Function:
the DigiPot function. See parameter group 3-9*
Digital Potentiometer.
3-13 Reference Site
Option: Function:
Select which reference site to activate.
[0] Linked to Use local reference when in hand-on mode, or
Hand / remote reference when in auto-on mode.
*
Auto
[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 Select this option to enable the FFACC factor in
H/A MCO 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. For more
information about FFACC, see VLT
Control MCO 305 Operating Instructions.
3-14 Preset Relative Reference
Range: Function:
0 % [-100 The actual reference, X, is increased or decreased
- with the percentage Y, set in parameter 3-14 Preset

reference Z. Actual reference (X) is the sum of the
inputs selected in:

Parameter 3-15 Reference 1 Source.
•
Parameter 3-16 Reference 2 Source.
•
Parameter 3-17 Reference 3 Source.
•
