Q25% Main encoder speed feedback
Units Encoder lines per second
Range –2

Default CAL
Reset H = CAL S = CAL P = CAL
_ Q24% shows the speed of the feedback encoder. This value is calculated
directly from the encoder lines and is not filtered.
_
Q26% Slave position offset
Units Encoder lines
Range –2
31
to 2
31
Default 0
Reset H = 0 S = 0 P = 0
_ Q26% defines the position offset to be added to _ Q4%. The offset
position profile only be used when there are no other position profiles
currently in operation.
_ Q26% can be applied when the slave is following a
speed profile.
If position control is being used ( _ Q32%.3 = 0) and S-ramps are selected
( _ Q32%.8 = 1), _ Q26% cannot be used.

Default 0
Reset H = 0 S = 0 P = 0
_
Q27% defines the slave speed offset. The offset can be applied during
other speed and position profiles, and is added to _ Q4% to provide the final
loop position reference, _ Q9%.
