Special Condition Description
INDICATION CONTENT DESCRIPTION
Zero Speed
Stopping
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)
Fail to start
directly
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.
Keypad
emergency stop
