INDICATION CONTENT DESCRIPTION
When speed F_11 = 0, Frequency lower limit F_7 = 0 and frequency setting < 1Hz
SP0 Zero Speed Stopping When speed F_11 = 1, Frequency lower limit F_7 < (F_6/100), and frequency setting
<Frequency upper limit (F_6/100)
1. If the inverter is set to external operation (F_10 = 1) and
direct start is disabled (F_28 =1),the AC drive cannot be started and will flash
SP1 Failure to start directly SP1 when the run command is attempted after applying power
(see descriptions of F_28 power-up start).
2. Direct start is possible when F_28 = 0.
The inverter setup to external operation (F_10 = 1). If the STOP
SP2
Keypad emergency key in the keypad is pressed during operation, the AC drive stops according the
