accelerates the motor back to its frequency reference before the fault
trip.
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.
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).
The block time parameter prevents overvoltage trips due to counter
electromotive force.
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.
