Description
This parameter is used to configure the thermal constant of the motor coil, which is the break frequency of a sin-
gle-pole low-pass filter model of the thermal dynamics of the motor coil.
This parameter, together with MOTOR.IPEAK and MOTOR.ICONT, determine the motor foldback parameters
IL.MFOLDD,IL.MFOLDT, and IL.MFOLDR.
Calculating MOTOR.CTF0
Given a motor coil/winding thermal time constant T in seconds, then:
MOTOR.CTF0 = 1/(2πT)
