EtherCATEtherCAT 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

Description

This parameter selects the feedback source that current loop uses for commutation angle calculation. It applies only when MOTOR.TYPE = 4.

0 = Primary feedback

1 = Secondary feedback

2 = Tertiary feedback

When IL"Instruction list" This is a low-level language and resembles assembly.FBSOURCE is changed, MOTOR.POLES and MOTOR.PHASE are updated.

IL.FBSOURCE MOTOR.PHASE is set to: MOTOR.POLES is set to:
0 FB1.MOTORPHASE FB1.MOTORPOLES
1 FB2.MOTORPHASE FB2.MOTORPOLES
2 FB3.MOTORPHASE FB3.MOTORPOLES

For induction motor closed loop control the commutation angle is set as shown in the following figure.
