Following Error, Encoder Position | Emerson P/N 400518-02 specs

Epsilon EP-I Indexing Drive and FM-2 Indexing Module Reference Manual

Following Error

The Following Error is the difference (in user units) between the Position Command and the Position Feedback. It is positive when the Position Command is greater than the Position Feedback.

Encoder Position

The motor position in encoder counts since power up when the value was set to zero. This is a signed 32 bit value. This is set to zero when the Absolute Position Valid output function is activated.

Pulse Input Posn

This parameter returns the total number of actual pulses received on the pulse input hardware. This value is active in all operating modes.
