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.
