Emerson unidrive m200 - Pre-Ramp Reference; Reference Offset; Jog Reference; Maximum Speed;Minimum Speed

Pre-skipFilterReference (01.002) is the reference before the skip filtering as indicated in Fig. 1.2.
Parameter 01.003 Pre-ramp Reference
Short description Displays the final output from the reference system
Mode Open‑loop
Minimum −VM_SPEED_FREQ_REF Maximum VM_SPEED_FREQ_REF
Default Units Hz
Type 32 Bit Volatile Update Rate 4ms write
Display Format Standard Decimal Places 2

Fig.1.3 shows the process from the Pre-skipFilterReference (01.002) to the Pre-rampReference (01.003). The Pre-rampReference (01.003) is the final output
from the Menu 01 reference system that is fed into the Menu 02 ramp system.
Parameter 01.004 Reference Offset
Short description Defines the the offset applied to the reference
Mode Open‑loop

If ReferenceOffsetSelect (01.009) = 0 then ReferenceSelected (01.001) is the selected reference multiplied by [1 + PercentageTrim (01.038) / 100.00)].
If ReferenceOffsetSelect (01.009) = 1 then the ReferenceOffset (01.004) is added to the selected reference to give ReferenceSelected (01.001).
If ReferenceOffsetSelect (01.009) = 2 then ReferenceSelected (01.001) is the selected reference plus the Maximumreferencefrequency multiplied by
(PercentageTrim (01.038) / 100.00). Maximumreferencefrequency is normally the value of MaximumSpeed (01.006) but refer to Variable
Maximum VM_SPEED_FREQ_REF for a full definition.
Parameter 01.005 Jog Reference

MaximumSpeed (01.006) provides a limit on the maximum speed demand. (If SelectMotor2Parameters (11.045) = 1 then M2MaximumSpeed (21.001) is
used instead.)
Parameter 01.007 Minimum Speed
Short description Defines the minimum value for the reference
Mode Open‑loop
Minimum −VM_NEGATIVE_REF_CLAMP1 Maximum VM_NEGATIVE_REF_CLAMP1

If NegativeReferenceClampEnable (01.008) = 1 then MinimumSpeed (01.007) is forced to be a negative value and is applied to the final reference as the
negative limit. If NegativeReferenceClampEnable (01.008) = 0 then - MaximumSpeed (01.006) is applied to the final reference as the negative limit. (If
SelectMotor2Parameters (11.045) = 1 then M2MinimumSpeed (21.002) is used instead.)
The minimum speed is also used to provide the minimum speed limit for uni-polar mode (i.e. BipolarReferenceEnable (01.010) = 0) after
the ReferenceSelected (01.001) as shown in Fig.1.2.
