Comments
Check this parameter to include the Speed0 max member to the input tag.
Speed maximum is the maximum observed speed measurement since last reset. This value is the maximum Speed,
not Factored Speed. So it excludes any multiplier that can be specified on the Speed page.
The maximum speed value does not update when the tachometer is in fault. See "Behavior" for the Dynamix Tacho
and Speed Measurement Object, page 384, for further information.
Tag Member: Speed0 max
Check this parameter to include the Speed1 max member to the input tag.
Speed maximum is the maximum observed speed measurement since last reset. This value is the maximum Speed,
not Factored Speed. So it excludes any multiplier that can be specified on the Speed page.
The maximum speed value does not update when the tachometer is in fault. See "Behavior" for the Dynamix Tacho
and Speed Measurement Object, page 384, for further information.
Tag Member: Speed1 max
Check this parameter to include the Speed0RateOfChange member to the input tag. This value is the Rate of Change of
the Speed, not of the Factored Speed. So it excludes any multiplier that can be specified on the Speed page.
Tag Member: Speed0RateOfChange
Check this parameter to include the Speed1RateOfChange member to the input tag. This value is the Rate of Change of
the Speed, not of the Factored Speed. So it excludes any multiplier that can be specified on the Speed page.
Tag Member: Speed1RateOfChange
Check this parameter to include the SMAX magnitude and phase members for the selected channel pair to the input
tag.
Channel Pair Tag Member
0, 1 Ch0_1SMAXMAg
2, 3 Ch2_3SMAXMAg
There are several different ways the SMAX measurement can be made. The 1444 performs the SMAX measurement per
standard ISO 7919/1, Annex A "Derivation of Measurements" Method A.
Check this parameter to include the Shaft Absolute pk-pk member for the selected channel pair to the input tag.
Channel Pair Tag Member
0, 1 Ch0_1Shaft AbsolutePk_Pk
2, 3 Ch2_3Shaft AbsolutePk_Pk
Check this parameter to include the Differential Expansion member for the selected channel pair to the input tag.
Channel Pair Tag Member
0, 1 Ch0_1DifferentialExpansion
2, 3 Ch2_3DifferentialExpansion
If the channel type is DC, then only one DC member can be selected (Differential Expansion, DC Proportional, or Rod
Drop). The mode for calculating the Differential Expansion measurement can be set to either Axial (Complimentary) or
Radial (Ramp). Use the Measurement Type control on the
Check this parameter to include the Overall (n) member for the selected channel to the input tag.
