Description
Position values transfered 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.
FB1.PSCALE 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 CAN
"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 6064 (Position Actual Value) and 60F4 (Following Error Actual Value).
Example
The drive always works internally with 64-bit position values. The drive internal 64-bit actual position should contain the following value:
0x0000.0023.1234.ABCD
The lower 32 bits represent the mechanical angle of the feedback. The upper 32 bits represent the number of turns.
FB1.PSCALE = 20
The 32-bit position is: 0x0231234A
FB1.PSCALE = 16
The 32-bit position is: 0x00231234
