Note:
Be aware of the following points when manually setting V/f patterns.
• To set linear V/f characteristics at frequencies lower than that of E1-06, set E-07 = E1-09. In this case, the setting for E1-08 will be
disregarded.
• Ensure that the five frequencies are set according to the following rules to prevent triggering oPE10 [V/f Data Setting Error];
E1-09 ≤ E1-07 < E1-06 ≤ E1-11 ≤ E1-04
• Setting E1-11 = 0 [Mid Point B Frequency = 0 Hz] disables E1-12 [Mid Point B Voltage]. Ensure that the four frequencies are set
according to the following rules;
E1-09 ≤ E1-07 < E1-06 ≤ E1-04
• Parameter E1-03 is not reset when the drive is initialized using A1-03.

NOTICE: Set this parameter to align with the drive input voltage (not motor voltage). The protective features of the drive will not
function if this parameter is incorrect. Failure to obey will cause incorrect drive operation.
Values Related to the Drive Input Voltage
The value set in E1-01 is the base value used for the motor protective functions in
drive, the detection level changes for some motor protective functions.
