FOLLOW
Configure following
Syntax aFOLLOWon/off(source,mode,scale)
Description
The Configure Following command is used to setup following, allowing an
axis to copy movement from another drive.
The source parameter specifies the device to follow. The only option is:
E – encoder input
The mode parameter determines the type of following move that takes place:
mode 1 The position of the motor follows the following source
All other mode values are reserved at present.
The scale parameter specifies the scaling applied to the following source.
This can range from 0.1 to 500% or –0.1 to –500% in steps of 0.1%.
Negative values reverse the sense of the following input.
With the following source set to “E” (encoder) the command following
position indicator (system variable PF) increments when pulses are received
by the following encoder input port according to the relationship:
PF = number of pulses received since following enabled * scale
PF accumulates in value at a rate proportional to the incoming pulses. In this
mode, turning following OFF, resets PF to zero.
Properties
