Omron SYSDRIVE 3G3JV

5-4
5-2 V/f Control
H 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 characteristic changes are required.
