running, the value will be displayed twice, but will not be written to memory. In sych a case, you
should stop the inverter. and set the value again.
• Standard setting mode is for a command, not for a parameter.
Therefore, when

Setting voltage/Frequency characteristics
Output voltage characteristics against output frequencies are set in the following manners:
Standard setting patterns are shown in Figure 3.1.
In the following cases, the "voltage/frequency characteristics" should be adjusted:
• When you want to run your motor at a frequency above 80Hz
• When you want to increase the start-up torque of your motor
