The CTRL menu branch can be accessed via the navigation
within the menu structure. The CtrL function contains sub-
functions which are displayed according to the operating point
of the frequency inverter.
Pressing the RUN key leads to a direct change from anywhere
within the menu structure to the motorpoti function
Pot
F
for
clockwise rotation or
Potr
for anticlockwise rotation.
If the drive is already running, the display reads
int
F
(forward,
clockwise) /
intr
(reverse, anticlockwise) for the function inter-
nal reference value or
inP
F
(forward, clockwise) /
inPr
(re-
verse, anticlockwise) for the function „Motorpoti (KP)“.
The function „Motorpoti (KP)“ enables linking to other reference
sources in the reference frequency channel. The function is
described in chapter „Reference values, Motorpoti (KP)“.
Motor potentiometer function

Using the arrow keys, you can adjust the output frequency of
the frequency inverter from the
minimum frequency
418
to the
maximum frequency
419
. The acceleration corresponds to the
factory setting (2 Hz/s) for the parameter
Ramp Keypad-
Motorpoti
473
. The parameters
Acceleration (clockwise)
420
and
Deceleration (clockwise)
421
are taken into account with
lower acceleration figures.
Internal reference value

The drive is in operation, i.e. output signals are present at the
frequency inverter and the current actual value is displayed.
Press an arrow key to switch to the motor potentiometer func-
tion

Using the arrow keys, you can adjust the output frequency of
the frequency inverter from
Minimum frequency
418
to
Maxi-
mum frequency
419
. The frequency value adjusted via the con-
trol unit can be linked to other reference values via the
Refer-
ence frequency source

(Chapter „Reference frequency
source“ and „Motorpoti (KP)“).
JOG frequency
JOG
This function is useful for manual setup and positioning of a
machine. The frequency of the output signal is set to the en-
tered value if the FUN key is pressed.
Press FUN key to switch from the internal reference value
int
or the motor potentiometer function
Pot
to parameter
JOG frequency
489
.
While keeping the FUN key pressed, press the arrow keys
to adjust the required frequency.
(The frequency value last adjusted is saved as the
JOG
frequency
489
.)
Release the FUN key to stop the drive.
(The display returns to the previous function
Pot
or
int
. or
inP
if function „Motorpoti (KP)“ is activated).
