11.6 E: Motor Parameters
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 parameter E1-01 [Input AC Supply Voltage] to match the input voltage of the drive. Drive input voltage (not motor
voltage) must be set in E1-01 for the protective features to function properly. Failure to set the correct drive input voltage will
result in improper 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 listed in the following table. The
detection level changes for some motor protective functions when using a 400 V class drive.
