Multi-function Compact Inverter 3G3MX2-EV2 User’s Manual (I666-E1)
The 3G3MX2-EV2 Series Inverter does not have a frequency matching restart function.
The operation when the following parameters are set for frequency pull-in restart is different from the
3G3MX2-E Series Inverter. It operates with frequency pull-in restart. For frequency pull-in restart, refer
to 7-7-1 Frequency Pull-in Restart on page 7-62.
•
When Power Interruption/Undervoltage Restart Selection (b001) is set to 02
•
When Overvoltage/Overcurrent Restart Selection (b008) is set to 02
•
When Free-run Stop Selection (b088) is set to 01
•
When Reset Restart Selection (C103) is set to 01
It operates with frequency matching restart.
The operation of frequency matching restart is as
follows.
At the time of restart, it recognizes a frequency from the
motor terminal voltage in a free-run stop state and
restarts according to that frequency.
Example: Example of power interruption/undervoltage
restart
At power-ON, it recognizes a frequency from the motor
terminal voltage in a free-run stop state and restarts
according to that frequency.
It operates with frequency pull-in restart at shutoff.
The operation of frequency matching restart is as
follows.
At the time of restart, the frequency at shutoff is output
to the motor. Once the output frequency and the output
voltage are balanced, the inverter performs normal
operation.
Example: Example of power interruption/undervoltage
restart
At power-ON, it executes pull-in restart at the output
frequency at shutoff.
