Spd Ref A Sel
Spd Ref B Sel
Speed Reference A, B Select
Selects the source for speed references while in “Auto” (typical) mode. When the drive is
in “Manual” mode, these sources are overridden (see P327). [Spd Ref A Sel] is the drive's
main speed reference. [Spd Ref B Sel] is an alternate speed reference. Selecting between
Reference A and Reference B is controlled by a digital input function (see parameters
173175 [DI Speed Sel n]) or by Logic Command bits 12…14 (sent over a
communication network).
When the speed reference is from a communication network, set this parameter to Port
0 and select parameter 874…877 [Port n Reference] as appropriate.
If the speed reference is from an encoder, set this parameter to Port 0 and select
parameter 134 [Aux Vel Feedback]. Configure parameter 132 [Aux Vel Fdbk Sel] to the
appropriate encoder. To access these parameters, set P301 [Access Level] to option 2
“Expert.”

Spd Ref A AnlgHi
Spd Ref B AnlgHi
Speed Reference A, B Analog High
Used only when an analog input is selected as a speed reference according to P545/550
[Spd Ref n Sel]. Sets the speed that corresponds to P51/61 [Anlg Inn Hi] on an I/O
module. This establishes scaling throughout the range.

Spd Ref Scale
Speed Reference Scale
Applies only in Flux Vector (FV) modes according to P35 [Motor Ctrl Mode]. Applies a
multiplier to P595 [Filtered Spd Ref] after it has been offset by the PID function (P1093
[PID Output Meter]). The scaled result, once limited, will become the primary
component of the value of P597 [Final Speed Ref].

MOP Reference
Motor Operated Potentiometer Reference

decremented) by digital input functions.
