: Frequency input reference destination
Adjustment range :
0.00
to
21.51
Factory setting
:
0.00
Used to select the destination of the numerical reference
resulting from conversion of the pulse signal. Only "non-bit"
type parameters can be programmed. If an unsuitable
parameter is selected,
3.46
will be frozen at 0.

: Vmin alarm threshold
Adjustment range : 0 to 500 rpm

: Vmax alarm threshold
Adjustment range : 0 to 500 rpm
Factory setting
: 90 rpm
Triggers an alarm
10.52
when the motor speed is such that:
- (
5.04
) > Vmax (
1.06
or
21.01
) -
3.52

to
: Not used
: Frequency input source
Adjustment range :
0.00
to
21.51
Factory setting
:
0.00
Used to select the source of pulses. Only "bit" type
parameters can be programmed. If an unsuitable parameter
is selected,
3.61
will be frozen at 0.
Note: Only use inputs ADI1, ADI2, DIO1, DI2 and DI3 as the
frequency input source. The maximum input frequency
should be 5 kHz. If the input frequency is more than 5 kHz,
use an encoder feedback option, and set
3.67
to 1 (EnCd).
: Input frequency
Adjustment range : 0 to 5000 Hz
Drive encoder frequency which will be converted to a
numerical reference.
Application example:
Pulses from an inductive sensor connected on a digital input
are converted to a reference which is assigned to the speed
reference.
: Maximum frequency output reference
Adjustment range : 0 to 1000.0 Hz
Factory setting
: 20.0 Hz
Adjusts the pulse frequency which should correspond to
100% of the original numerical reference.
Note: Set
3.63
above 0.5 Hz, since the drive output is
inactive below this value.
: Frequency output reference scale
Adjustment range : 0 to 32.00
Factory setting
: 1.00
Used for scaling the reference from the drive encoder.
: Frequency output reference
Adjustment range : 0 to 100%
Indicates the value of the analog reference.
: Not used
: Frequency input select (
)
Adjustment range : 0 or 1
Factory setting
: 0
0 (Digital in) (Freq): An analog reference is generated
from a frequency signal.
1 (Encoder) (Encd): The encoder signal is used to generate
an analog reference (e.g. speed reference).
: Minimum frequency threshold
Adjustment range : 1.0 to 10.0 Hz
Factory setting
: 1.0 Hz
This parameter is used to define a minimum signal absence
detection time for the frequency input. Used to adapt
detection to the period of the signal.
This minimum time = 1/(
3.68
).
and
:Not used
: Frequency output reference source
Adjustment range :
0.00
to
21.51
Factory setting
:
0.00
Used to select the source of the numerical reference which
will be converted into pulses.
: Frequency output period
Adjustment range : 0.001 to 2.000 s
Frequency output period resulting from conversion of the
numerical reference.
Application example:
A potentiometer connected to an analog input generates a
reference which is converted into pulses whose period is
proportional to the reference. The pulses are assigned to the
run command.
: Frequency output signal
Adjustment range : 0 or 1
0 (Off) (OFF)
1 (On) (On)
Used to assign the drive output to a digital output if necessary,
e.g. DIO1.
Note: There is no counting above 2 seconds.
