8. Click [Save File] to save the completed motor file (use same filename as the initial data in step 1).
Click [Update Drive] to load the motor data to the drive.
5.2.5 Custom Motor Data Entry
A Custom Motor file is created by entering motor data into the “Motor Parameters” dialog box. This box
is divided up into four sections: Electrical constants, Mechanical constants, Feedback and Gain Scaling.

When creating a custom motor, input the value of all parameters listed for the specific motor type. All
entries are mandatory except motor inertia (Jm). Enter a value of 0 for the motor inertia if the actual value
is unknown.
5.2.5.1 Electrical & Mechanical Constants
Motor Torque Constant (Kt)
Enter the value and select proper units from the drop-down list.
NOTE
Round the calculated result to 3 significant places.
Motor Voltage Constant (Ke)
The program expects Ke to be entered as a phase-to-phase Peak voltage. If you have Ke as an RMS value,
multiply this value by 1.414 for the correct Ke Peak value.
Phase-to-phase winding Inductance (Lm)
This must be set in millihenries (mH). The phase-to-phase winding Inductance (L) will typically be between
0.1 and 200.0 mH.
NOTE
If the units for the phase-to-phase winding Inductance (L) are given in micro-henries
(µH), then divide by 1000 to get mH.
Phase-to-phase winding Resistance (Rm) in Ohms
This is also listed as the terminal resistance (Rt). The phase-to-phase winding Resistance (R) will typically
be between 0.05 and 200 Ohms.
Nominal phase current (RMS Amps)
Nominal continuous phase current rating (In) in Amps RMS. Do not use the peak current rating.
