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

EtherCAT ***EtherCAT is an open, high-performance Ethernet-based fieldbus system. The development goal of EtherCAT was to apply Ethernet to automation applications which require short data update times (also called cycle times) with low communication jitter (for synchronization purposes) and low hardware costs CoE and CANopen CANopen
