Fig. 5-1-2 Speed tracking restart diagram
Starting process includes the start of inverter power on, power recover, external
fault reset, and restart after coast-to-stop.
Tips:
Models of 3018G/3022P and aboves can take speed tracking function ; Models of
35R5GB/37R5PB~3015GB/3018PB need to install a matched speed tracking board if
they want to take speed tracking function; Models of 3004GB/35R5PB or below have
not this function.
P1.01 Start frequency
Range: 0.10~60.00Hz【0.50Hz】
P1.02 Start frequency holding
time
Range: 0.0~10.0s【0.0s】
Note:
Start frequency is the initial frequency at which the inverter starts, see f
S
as shown in Fig.
5-1-3 ; Holding time of starting frequency is the time during which the inverter operates
at the starting frequency, see t
