Speed Search Operation Setting Details
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.
