AXIS#.CANOPEN.PSCALE

Description

Internal position values transferred over fieldbus are converted from native 64-bit values to a maximum 32-bit position value. This parameter sets the resolution/revolution of position values back to the controller.

This value determines the counts per revolution of position values delivered by fieldbus. The default value is 20, which yields 2^20 counts/revolution. This scaling is used for CANClosed"Controller area network" CAN is a broadcast, differential serial bus standard developed for connecting electronic control units. Each node is able to send and receive messages, but not simultaneously PDOs 6063h (Position actual internal value) and 60FCh (Position demand internal value).

Example

With units = counts 32 bit (ie: 2^32 counts/revolution), the default PSCALE of 20, and AXIS#.PL.FB = 2147483648.000 [Counts], which is half of 2^32, meaning a position of 180 degrees. The position actual internal value (6063h) over the fieldbus would be 2^20 / 2 = 524288 counts.

EtherCATClosedEtherCAT 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 AXIS1.CANOPEN.PSCALE 0x5003h 0x1 U8 1:1 - Read/Write False
