550 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
173…175 [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.” Default:

551 Spd Ref A Stpt
Spd Ref B Stpt
Speed Reference A, B Setpoint
A constant speed value (similar to a preset speed) to be used as a possible source for
P545 and P550. Units:
Default:
Min/Max:

RPM
0.0000 Hz
–/+P27 [Motor NP Hertz] x 8
–/+P28 [Motor NP RPM] x 8 RW Real

552 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. Units:
Default:
Min/Max: Hz

548
553 Spd Ref A AnlgLo
Spd Ref B AnlgLo
Speed Reference A, B Analog Low
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 Lo] on an I/O
module. This establishes scaling throughout the range. Units:
Default:
Min/Max: Hz

554 Spd Ref A Mult
Spd Ref B Mult
Speed Reference A, B Multiplier
Applies multipliers to speed references A and B respectively. Default:
Min/Max: 1.00
–/+22000.00 RW Real
555 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]. Default:
Min/Max: 1.000
0.000 / 1000.000 RW Real
556
557 Jog Speed 1
Jog Speed 2
Jog Speed n
The speed used for jogging when the Jog 1 or Jog 2 function (respectively) is activated
by a digital input function or by Logic Command (sent over a communication network). Units:
Default:
Min/Max:

Based on P27 [Motor NP Hertz]/P28 [Motor
NP RPM] and Voltage Class
–/+P27 [Motor NP Hertz] x 8
–/+P28 [Motor NP RPM] x 8 RW Real
558 MOP Reference
Motor Operated Potentiometer Reference
Value of the MOP (Motor Operated Potentiometer) Reference to be used as a possible
source for P545/550 [Spd Ref n Sel]. The MOP Reference is activated (incremented or
decremented) by digital input functions. Units:
Default:
Min/Max: %
