Starting Frequency And Starting Time; Dc Injection Braking Function - Alpha 6000 User Manual

Chapter 5 Parameter Introductions
Start Freq.
 Tips:
1．Starting frequency is not restricted by the frequency lower limit.
2．If reference frequency is lower than starting frequency during acceleration, the
inverter will run at zero-speed.
P1.03 DC injection braking current at
start
P1.04 DC injection braking time at start Range: 0.0~30.0s【0.0s】
Note:
P1.03 and P1.04 are only active when P1.00 is set to 1 (start mode 1 is selected), as
shown in Fig. 5-1-1.
The range of DC injection braking current and time are dependent on the inverter model,
see Table 5-1-1.
DC injection braking current is a percentage value of inverter rated current. When the
braking time is set to 0.0s, the DC injection braking process will not happen

Note:
Refer to Fig. 5-1-1, the inverter outputs DC injection braking current at start
(P1.03), during DC injection braking time at start.
