Code Description
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 [at DRV-14 (Motor Capacity)] are used.
CON-75 SS Block
Time
The block time parameter prevents overvoltage trips due to counter
electromotive force by cutting off the inverter output for the set time before
carrying out a speed search.
Note
• If operated within the rated output, the iS7 series inverter is designed to withstand
instantaneous power interruptions of up to 15 ms and maintain normal operation [when 200
–
230 V AC input voltage is supplied to 200 V class model types, and 380 – 460 V AC input voltage is
supplied to 400 V class model types, and when the inverter is operating with static load current
(CT load)].
• The DC voltage inside the inverter changes depending on the load. Low voltage fault trips may
result if the power interruption lasts longer than 15 ms, or the output voltage exceeds the rated
input voltage.
8.20 Auto Restart Settings
When inverter operation stops due to a fault and a fault trip is activated, the inverter
automatically restarts based on the parameter settings.
