Mode
Pos Trim Mode
Selects how the position
regulator output is used to trim
the follower drive speed
reference (master encoder
frequency).
0: Constant
The position regulator
output is independent of the
master encoder speed
reference.
1: Speed Prop
The position regulator
output is proportional to the
master encoder speed
reference.
Note: ELS modes only.
