Starting with power-on:
Set bit 4 to ‘1’ and ADV-10 (Power-on Run) to ‘1
(Yes)’. If inverter input power is supplied while the inverter operation
command is on, the speed search operation will accelerate the motor up to
the frequency reference.
CON-72 SS Sup-
Current
The amount of current flow is controlled during speed search operation
based on the motor’s rated current. If CON-70 (SS mode) is set to ‘1 (Flying
Start-2)’, this code is not visible.
CON-73 SS P-Gain,
CON-74 SS I-Gain
The P/I gain of the speed search controller can be adjusted. If CON-70 (SS
Mode) is set to ‘1(Flying Start-2)’, different factory defaults, based on motor
capacity, are used and defined in DRV-14 (Motor Capacity).
CON-75 SS Block
Time The block time parameter prevents overvoltage trips due to counter
electromotive force.
Note
If operated within the rated output, the H100 series inverter is designed to withstand instantaneous
power interruptions within 8 ms and maintain normal operation. The DC voltage inside the inverter
may vary depending on the output load. If the power interruption time is longer than 8 ms, a low
voltage trip may occur.
Select the Speed search function (normal acceleration) for a proper re-operation during a free-run.
If the speed search function (normal acceleration) is not selected during the acceleration, an over
current trip or an overload trip may occur.
