P137 f_stop_analog
Stop frequency from analogue rated frequency signal; this makes it possible to achieve an automatic
motor stop with counter-clockwise rotation of the nominal value potentiometer or analogue voltage 0 V.
The motor is automatically stopped if the rated frequency default at analogue input AIN1 falls below the
value of this parameter. By means of parameter P8-speed display, this parameter can be changed from
frequency display to speed display, the number of poles of the motor P96-no. of poles being taken into
account. In this context, also see the parameter P135-f_rem_min and P136-f_rem_max.
Special values: Off - no automatic stop
f_mot_min - the value from P41-f_mot_min is used
Minimum value: 30 Hz
Maximum value: 4,000 Hz
Factory setting: Off
P140 input for start
With this, the input for the motor start is determined. This parameter is displayed and evaluated only
when P7- Operational Mode is set to Selection.
Value: PC application - Start/stop is implemented via the control panel (start, nominal
values)
Remote control - Start/stop is implemented via inputs IN1 and IN2 of the
remote control, see P110-input IN1 and P111-input IN2.
Factory setting: Remote control
P141 input for f_soll
With this, the input for the frequency nominal value is determined. This parameter is displayed and
evaluated only when P7-select operation is set to "Selection". Via P142-enabling FF, alternative fixed
frequency nominal values - so-called fixed frequencies - can be activated. The method is clearly
described in chapter 4.6
Value: PC application - The value of the control panel in P1–N_rated is used as the
frequency value
AIN - The frequency value is calculated from the voltage at the
analogue input AIN. The frequency limits are set via
parameters P135-f_rem_min and P136-f_rem_max. The
calculated value can be seen in P10-N_rated _act.
Factory setting: AIN
P142 enabling FF
With this, the fixed frequencies are made available. This parameter is displayed and evaluated only when
P7-select operation is set to "Selection". The method is clearly described in chapter 4.6.
Value: Blocked - The fixed frequencies are blocked. The nominal value load is
effected from the input indicated in P141-input for f_soll.
On - The fixed frequencies are available. The choice of which
frequency is to be used as the nominal value is implemented
via the digital inputs IN5 und IN6. The fixed frequencies
themselves are stored in the parameters P104-FF1 to P106-
FF3. The current value can be seen in P10-N_rated_act.
Factory setting: Blocked
