TOEPYAIHV6002A HV600 Drive Programming
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
.

Input AC Supply Voltage
Sets the drive input voltage.
208 V Class: 240 V,
480 V Class: 480 V
(208 V Class: 155 - 255 V,
480 V Class: 310 - 510 V)
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
. With a
480 V class drive, the detection level changes for some motor protective functions.

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.

(Determined by A1-02)
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.
