Description
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.
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 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
