Special Condition Description

DESCRIPTION
When F_11 = 0, F_7= 0 and frequency setting < 1 Hz
When F_11 = 1, F_7<(F_6/100), and frequency setting
<(F_6/100)
1. If the inverter is set to external operation (F_10 = 1) and
direct start is disabled (F_28 =1), the inverter cannot be
started and will flash SP1 when operation switch turned to
ON after applying power (see descriptions of F_28).
2. Direct start is possible when F_28 = 0.
The inverter setup to external operation (F_10=1). If the STOP
key in the keypad is pressed at the middle of operation, the
inverter stops according the setting in F_14 and flash SP2 after
stop. The RUN switch must be turned OFF than ON to restart

when F_22 = 1
2. Attempt to set F_22 to 1 when
F_04 = 1
1. Press ▲ or ▼
F_11=1 or under sp1 operation
2. Attempt to modify F_29
3.Attempt to modify parameter that
is not allowed to be modified
during operation
