◆Starting process includes the start of ac drive 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 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 ac drive starts, see f
S
as shown in Fig.
5-1-3 ; Holding time of starting frequency is the time during which the ac drive operates
at the starting frequency, see t

Fig. 5-1-3 Starting frequency and starting time
Tips:
1．Starting frequency is not restricted by the frequency lower limit.
2．If reference frequency is lower than starting frequency during acceleration, the ac
drive will run at zero-speed.
P1.03 DC injection braking current at
start
This value depends on the ac drive model
【0.0%】
P1.04 DC injection braking time at start
Range: 0.0～30.0s【0.0s】
