● If a standard PTC resistor is used, the corresponding resistance of mo‐
tor protection reference is 1330 Ω. If a general resistor is used, the cor‐
responding motor protection reference is shown in the table below:

E4.09
Phase loss protection Factory default 0
Setting range 0...3 Minimum unit 1
● 0: Both input and output phase loss protection active
– Frequency converter input phase loss protection is active, and ope‐
rating panel displays IPH.L.
– Frequency converter output phase loss protection is active, and
operating panel displays OPH.L.
● 1: Only input phase loss protection active
● 2: Only output phase loss protection active
● 3: Neither input or output loss protection active
E4.10
+I broken wire reaction mode (4...20
mA)
Factory default 0
Setting range 0...4 Minimum unit 1
This parameter is used to decide the action of the frequency converter in
case of +I wire broken when the set frequency of the frequency converter is
set by analog input +I (4...20 mA).
● 0: No action
● 1: Running with upper frequency (Alarm)
The frequency converter continues running at [b1.06] 'Upper frequency'
with the alarm code 'B.W.A' displayed on the operating panel.
● 2: Running with lower frequency (Alarm)
The frequency converter continues running at [b1.07] 'Lower frequency'
with the alarm code 'B.W.A' displayed on the operating panel.
● 3: Running with setting frequency before wire broken (Alarm)
The frequency converter continues running at 'Setting frequency before
wire broken' with the alarm code 'B.W.A' displayed on the operating
panel.
● 4: Stop (Fault)
The frequency converter stops running with the fault code 'B.W.F' dis‐
played on the operating panel.
