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 AXIS#.MOTOR.AUTOSET = 1 and can be modified while AXIS#.MOTOR.AUTOSET = 1 if its AXIS#.MOTOR.DISAUTOSET index = 1.
