FB3.P

Description

This parameter reads the position back from the tertiary feedback deviceA 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 connected to X9, when DRV.EMUEMODE = 11. The position can be read as 64-bit signed count or in customer units. The position value FB3.P depends on FB3.DIR and FB3.POFFSET.

This parameter is only supported on drives with model numbers similar to AKD-x-xyyzz-NBxx-yyzz and only works with Endat 2.2 multiturn encoder. The output format is 32:32 the upper 32 bits represents the multiturns and the lower 32 bits for position of the feedback.
