Code and
Features
Description
•
Starting with power-on: Set bit 4 to 1 and Ad.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.
Cn.72 SS Sup-
Current
The amount of current flow is controlled during speed search
operation based on the motor’s rated current. If Cn.70 (SS mode) is
set to 1 (Flying Start-2), this code is not visible.
Cn.73 SS P/I-Gain,
Cn.75 SS Block
Time
The P/I gain of the speed search controller can be adjusted. If Cn.70
(SS Mode) is set to 1 (Flying Start-2), different factory defaults based
on motor capacity are used and defined in dr.14 (Motor Capacity).
Note
•
If operated within the rated output, the G100 series inverter is designed to withstand
instantaneous power interruptions within 15 ms and maintain normal operation. Based
on the rated heavy load current, safe operation during an instantaneous power
interruption within 15ms is guaranteed for 200 V and 400 V inverters (whose rated
input voltages are 200
–230 VAC and 380–460 VAC respectively).
•
The DC voltage inside the inverter may vary depending on the output load. If the power
interruption time is longer than 15 ms, a low voltage trip may occur.
When operating in sensorless mode for the load that works in free-run, the speed search
function (for general acceleration) must be set for smooth operation. If the speed search
function is not set, an overcurrent trip or overload trip may occur.
