FB#.POLES

Description

FB#.POLES sets the number of individual poles in a resolver feedback deviceClosedA process whereby some proportion of the output signal of a system is passed (fed back) to the input. In automation, a device coupled to each motor to provide indication of the motor's shaft angle, for use in commutating the motor and controlling its speed and position. This variable is used for the commutation function, as well as for velocity feedback scaling, and represents the number of individual poles (not pole pairs). The division value of motor poles (AXIS#.MOTOR.POLES ) and feedback poles (FB#.POLES) must be an integer when moving drive to enable, otherwise a fault is issued.

Fieldbus Information

FieldbusClosedA Fieldbus is an industrial network system for real-time distributed control (e.g. CAN or Profibus). It is a way of connecting instruments in a plant design Parameter Index Sub-Index Data Type Float Scale Units Access PDOClosedPDO is a type of protocol frame used in some fieldbuses. A PDO contains one or more object dictionary entries, which define the application data transferred between devices. Mappable
EtherCATClosed***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 FB1.POLES 0x3500 0x3 UINT - - RW False
