Coil Thermal Constant (MOTOR.CTF0)
The Coil Thermal Constant, along with the peak current setting, determines the rate of change of the decrease in motor current during a foldback condition. When creating a custom motor in Workbench, you will need to know the Coil Thermal Constant. Since this parameter is not provided for most motors, you can calculate it using the formula below.
Coil Thermal Constant in mHz = 1000 / (2 * PI * (Thermal Time Constant in sec. / 30.0))
The Customer motor settings in Workbench has the Coil Thermal Constant in mHz.
