b1.03
Range: 0.00~50.00
Default: 0.00
Startup
frequency
Unit: Hz
Start frequency is the initial frequency of drive from stop to start. It not
restricted by lower frequency limit. If setting frequency less than startup
frequency, the drive will run with the frequency of zero.
b1.04
①
Range: 0.0~100.0
Default: 0.0
Startup
frequency
holding time
Unit: s
When startup, drive will run and use the frequency of b1.03, it will holding
the frequency base on b1.04 then accelerate to setting frequency.
Note:
If the set target frequency is lower than the startup frequency, the
drive will not start.
During switchover between forward rotation and reverse rotation, the
startup frequency holding time is disabled.
The holding time is not included in the acceleration time.
The holding time is included in the running time of PLC.
b1.05
Range: 0~1
Default: 0
Start mode
0: Ramp start from startup frequency
It is applicable to small-inertia load. DC braking before the start is
applicable to drive of load such as elevator and crane.
Startup frequency is applicable to drive with burst start under start torque,
such as cement mixer.
1: Rotational speed tracking start
It is applicable to large-inertia load. If the load motor is still rotating due to
the inertia when the drive starts, this mode is used to prevent start
overcurrent.
