Functional description
Increase output frequency
In order to gradually increase the output frequency, the signal at input
“
E1
”
is switched on via contact
“
C1
”
. The signal must be higher than set for
“
E1 Max.
”
(i.e. over 8 V). The output frequency is now
increased depending on the duration of the signal applied and the increment setting
“
Touch function.-
step
”
. For every 100 ms of the signal applied (interval not adjustable), the output frequency increases
by 0.20 %.
Increasing output frequency is stopped if at
“
E1
”
the set value for
“
E1 Min.
”
is not reached (i.e. is
below 3 V).
Reduce output frequency
In order to gradually reduce the output frequency, the signal at input
“
E2
”
is switched on via contact
“
C2
”
. The signal must be higher than set for
“
E2 Max.
”
(i.e. over 8 V). The output frequency is now
reduced depending on the duration of the signal applied and the increment setting
“
Touch function.-
step
”
. For every 100 ms of the signal applied (interval not adjustable), the output frequency decreases
by 0.20 %.
Reducing the output frequency is stopped if at
“
E2
”
the set value for
“
E2 Min.
”
is not reached (i.e. is
below 3 V).
Information
Please note the following information to prevent unde
fi
ned states:
•
“
Always set E1 Max.
”
higher than
“
E1 Min.
”
and always set
“
E2 Max.
”
higher than
“
E2 Min.
”
.
•
Do not activate both inputs (E1 and E2) at the same time with increase and reduction signals (either
lock
“
C1
”
or
“
C2
”
).
Settings in IO Setup

E2 min.
Reducing the output frequency is stopped if at

”
the set value for
“
E2 Min.
”
is not
reached.
Setting range: 10 - 100 %
Factory setting: 100 %
Increment setting per 100 ms
Touch function.step
Touch function.step
Added increment if the respective switching thresholds for
“
E1
”
or
“
E2
”
are exceeded.
The setting corresponds to the maximum possible frequency range (0 - 100 %
0 -
50 Hz @ 50 Hz. max. frequency).
Adjustment range: 0.00 - 100.00 %
Factory setting: 0,20 %
