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	5362h/0	M_01-08-00-000

Description

The value of IL"Instruction list" This is a low-level language and resembles assembly.IMID can be estimated using the motor name plate information.

The following rule should generally be used:

In which Id is the value for IL.IMID, the preset rotor flux building current, Ir is the name plate phase current, cosϕ is the name plate power factor at rated and operation, and 0.8 is an empirical factor (accounts for the angle error due to voltage drop on the leakage induction).
