V/F Control - Omron SYSDRIVE 3G3JV Series User Manual

Basic Operation

5-2 V/f Control

Setting the V/f Patterns (n09 to n15)
Set the V/f pattern so that the motor output torque is adjusted to the required load
torque.
The 3G3JV incorporates an automatic torque boost function. Therefore, a maximum of
150% torque can be output at 3 Hz without changing the default settings. Check the
system in trial operation and leave the default settings as they are if no torque charac-
teristic changes are required.
