1-6-5 regulation start / stop
In Control mode, if the frequency converter operates durably near to the fmin frequency within a
given hysteresis, this appoints the time limit after which “waiting” state will be effectuated, and it
appoints also the value of the error signal which starts the control process again.
(e g. if a pump does not convey for a prolonged time, its operation is superfluous!)
1-6-5-1 time limitation
With setting “N”, the duration of operating
at fmin is not limited

If the frequency is in this range above the
minimum frequency, time limitation starts,

1-6-7 dimension
This serves establishing and displaying the
reference signal in a way easier corresponded to
the manufacturing process.
The correspondence should refer to 100 %.
For example, in a printery compressed air will be
produced with a compressor for the machinery.
The pressure of the compressed air will be
measured with a remote transmitter and the
control occurs to this pressure.
If the 100 % reference signal corresponds to 20
bar pressure, then after setting the
correspondence to 20 and the dimension to bar in
menu 1-2 the control reference signal will be
displayed in bar instead of %.

feedback
Permits the selection of the source of the feedback signal used with regulation tasks.
(Setting the parameters of the input is made in the 4. Inputs menu!)
1-7-1 source of the feedback signal
In case of simple torque control (6-28 Operation
mode: „U/f”) the motor parameters are ruling.
(6. Motor menu)
In case of torque control with signal transmitter
(6-28 Operation mode: „with signal transmitter”)
the measured rotation speed and the output
frequency are ruling.
It is important to set the nominal rotation speed
belonging to the nominal torque of the motor!
(6. Motor menu).
The output frequency sets between „0” and fmax
in the way that the motor can deliver as a
maximum those percent of its torque, set with the
control reference signal!
