MOTOR.CTF0

Description

This parameter is used to configure the thermal constant of the motor coil, which is the break frequency of a single-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)

This parameter is automatically configured for Kollmorgen motors when MOTOR.AUTOSET=1.
