Range Description / Notes
[Default]
0 - 1 Automatic restart after fault:
[0]
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. The display flashes during this condition.
WARNING:
While waiting to re-start, the display will flash. This means
that a start is pending and may happen at any time. Fault
codes can be observed in P140 and P930.
0.00 - 10.00 Frequencies set by P014, P027, P028 and P029 that are within +/- the value
[2.00] of P019 of all skip frequencies are suppressed.
0 - 650.00 Frequency corresponding to the lowest analogue input value, i.e.
[0.00] 0 V/0 mA or 2 V/4 mA, determined by P023 and the settings of the DIP
selector switches 1, 2 and 3 (see Figure 4.1.2). 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).
0 - 650.00 Frequency corresponding to the highest analogue input value, i.e.
[50.00] 10 V or 20 mA, determined by P023 and the setting of the DIP selector
switches 1, 2 and 3 (see Figure 4.1.2) This can be set to a lower value than
P021 to give an inverse relationship between analogue input and frequency
output.
i.e.
f
Note: The output frequency is limited by values entered for P012/P013.
