12.5 E: MOTOR
610 SIEPYEUOQ2A01A AC Drive Q2A Technical Manual
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 B Frequency = 0 Hz] disables E1-12 [Min Output 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.

Input AC Supply Voltage
Sets the drive input voltage.
400 V: 400 V
(400 V Class: 310 to 510 V)
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 Table 12.29. With a 400 V class
drive, the detection level changes for some motor protective functions.

built-in braking transistor. Refer to ““Braking Unit, Braking Resistor Unit Instruction Manual (TOBPC72060001)”” for more
information.

V/f Pattern Selection
Sets the V/f pattern for the drive and motor. You can use one of the preset patterns or you can
make a custom pattern.
F
(Determined by A1-02)
Note:
• When A1-02 = 2 [Control Method = OLVector], settings 0 through E are not available.
• 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 [Init Parameters] will not initialize the value E1-03.
0 : CT_50-50Hzmax
Use this constant torque pattern for general applications. Use this pattern when the load torque is constant and
there is no rotation speed. For example, linear conveyor systems.
