Description / Notes
P018 •••• Automatic restart after fault 0 - 1
[0]
Automatic restart after fault:
0 = Disabled
1 = The inverter will attempt to restart up to 5 times after a fault.
If the fault is not cleared after the 5th attempt, the inverter
will remain in the fault state until reset.
There is an increasing time delay between each restart
attempt.
P019 •••• Skip frequency bandwidth (Hz) 0 - 10.00
[2.00]
Frequencies set by P014, P027, P028 or P029 that are within +/- the
value of P019 are suppressed.
P020 Flying start ramp time (seconds) 0.50 - 25.0
[5.0]
Used in conjunction with P016 (set longer times if persistent F002
trips occur).
P021 •••• Minimum analogue frequency
(Hz)
0 - 120.00
[0.00]
Frequency corresponding to the lowest analogue input value, i.e.
0 V / 0 mA or 2 V / 4 mA. This can be set to a higher value than P022
to give an inverse relationship between analogue input and frequency
output (see diagram in P022).
P022 •••• Maximum analogue frequency
(Hz)
0 - 120.00
[50.00]
Frequency corresponding to the highest analogue input value, i.e.
10 V / 20 mA, determined by P023. This can be set to a lower value
than P021 to give an inverse relationship between analogue input and
frequency output.
i.e.
Note: The output frequency is limited by values entered for
P012/P013.
P023 •••• Analogue input type 0 - 2
[2]
Selects analogue input type according to the setting of jumpers
JP300/JP301:
JP301 closed
OR JP300 closed
0 = 0 V to 10 V 0 mA to 20 mA
1 = 2 V to 10 V 4 mA to 20 mA
2 = [2 V* to 10 V] 4 mA* to 20 mA
* The inverter will come to a controlled stop if V < 1 V or 2 mA.
WARNING: The motor can automatically run without a
potentiometer or voltage source connected
between pins 3 and 4.
With P023=2, the motor will automatically start
when V exceeds 2 V. This equally applies to
analogue and digital control (i.e. P006 = 0 or 1).
P024 •••• Analogue setpoint addition 0 - 2
[0]
If the inverter is not in analogue mode (P006 = 0 or 2), setting this
parameter to ‘1’ causes the analogue input value to be added.
0 = No addition.
1 = Addition of the analogue setpoint (defined by P023) to the
fixed frequency or the motor potentiometer frequency.
2 = Scaling of digital/fixed setpoint by analogue input (P023) in
the range 0 - 100%.
Note: By selecting a combination of reversed negative fixed
frequency settings and analogue setpoint addition, it is
possible to configure the inverter for ‘centre zero’ operation
with a +/-5 V supply or a 0 - 10 V potentiometer so that the
output frequency can be 0 Hz at any position, including the
centre position.
