Multi-function Compact Inverter 3G3MX2-V1 User’s Manual (I585-E1)
Use this function to increase the voltage slowly during motor startup.
To prevent the surge current or overcurrent trip during startup, increase the value set in the Reduced
Voltage Startup Selection (b036). Although setting a small value causes the high starting torque, the
inverter operates as with the full voltage starting. Therefore, an overcurrent trip may occur easily.
Use the frequency jump function to avoid the resonant point of the load machine during operation.
If jump frequency is set, you cannot set the frequency reference within the jump frequency range to
avoid steady operation in that range.
The output frequency changes continuously according to the acceleration/deceleration time settings
during acceleration/deceleration.
You can set three points for jump frequency.
