5.5 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 E1-06 [Base Frequency], set E1-07 = E1-09 [Mid Point A Frequency = Minimum
Output Frequency]. In this application, the drive ignores E1-08 [Mid Point A Voltage].
• Set the five frequencies as specified by these rules: Incorrect settings will cause oPE10 [V/f Data Setting Error].
E1-09 ≤ E1-07 < E1-06 ≤ E1-11 ≤ E1-04 [Minimum Output Frequency ≤ Mid Point A Frequency < Base Frequency ≤ Mid Point B
Frequency ≤ Maximum Output Frequency]
• 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
• When you use A1-03 [Initialize] to initialize the drive, it will not reset E1-03.

E1-01: Input AC Supply Voltage
No.
Name
(Hex.)
E1-01 Input AC Supply Voltage
(0300)
NOTICE: Set parameter E1-01 to align with the drive input voltage (not motor voltage). If this parameter is incorrect, the protective
functions of the drive will not operate correctly and it can cause damage to the drive.
Values Related to the Drive Input Voltage
The value set in E1-01 is the base value that the drive uses for the motor protective functions in
480 V drive, the detection level changes for some motor protective functions.

E1-03: V/f Pattern Selection
No.
Name
(Hex.)
E1-03 V/f Pattern Selection
(0302)
Note:
• Set the correct V/f pattern for the application and operation area. An incorrect V/f pattern can decrease motor torque and increase current
from overexcitation.
• Parameter A1-03 [Initialize Parameters] will not initialize the value of E1-03.
