Multi-function Compact Inverter 3G3MX2-V1 User’s Manual (I585-E1)
(2) Set the rated frequency of the motor in the 1st Base Frequency (A003) and set the
maximum frequency in the 1st Maximum Frequency (A004).
The rated/maximum frequency values can be calculated from the rated/maximum rotation
speed of the PM motor as follows:
(3) Set the rated voltage of your PM motor in the 1st Motor Rated Voltage Selection
(A082) and set the rated current in the PM Motor Rated Current (H105).
The 1s Motor Rated Voltage Selection parameter must be set to the highest value closest to
the rated voltage of the motor.
In addition, for the purpose of overload protection, set the rated current of the PM motor in
the 1st Electronic Thermal Level (b012).
(4) In the PM Motor Parameter Ke (H109), set the inductive voltage parameter of the PM
motor.
Obtain the datasheet of your PM motor from the motor manufacturer and set the inductive
voltage parameter (for one phase).
This value must be set in “Vp/(rad/s).” If the datasheet provides this parameter in a different
unit, you need to perform unit conversion.
(5) In the PM Motor Parameter J (H110), set the moment of inertia of your PM motor.
Calculate the motor-shaft conversion of the moment of load inertia, add the moment of iner-
tia of the motor to it, and set the sum.
(6) Set the DC Injection Braking Selection (A051) to 00 (Disabled) (default).
If the DC Injection Braking Selection (A051) is set to 01 (Enabled), change it to 00 (Dis-
abled).
If these parameters are set to Enabled, auto-tuning will not be completed.
(7) Set the motor cable length in the Motor Cable Length (b033).
Set the Motor Cable Length (b033) according to the length of your motor cable.
Example
If, for a 4-pole PM motor, the inductive voltage parameter for one phase is 10 [mV/r/min],
the set value can be calculated as follows:
10 [mV/r/min] = (10/1000 [V])
