Motor potentiometer reference copy “MotPotRefCopy”
This parameter defines how reference is handled when reference input is changed to
motor potentiometer in I/O control.
0 “No copy”
Reference is not copied. Depending on “MotPot Reset” function, the drive may start
from minimum frequency or from reference that was last used when the drive was run
with motor potentiometer.
1 “Reference”
The drive’s active reference is copied. If the drive is ramping when the value of
motor potentiometer is changed the drive will continue ramping after the change.
This allows the reference copy in stop state unless the “MotPot Reset” function
overruns it (e.g. reset in stop state is not selected).
2 “Freq. Output”
Speed at the time of change is copied to reference. If the drive is ramping when the
change is made the drive will stop ramping and keep the present speed.
5.2.7 Adjust reference
Adjust reference function is used to fine tune the main
reference. Adjust reference is added to main reference after
“SpeedShare” function “See Figure below”
