work together as follows:
Display =
Input frequency (Hz)
×
RAtE SCLE
RAtE INPt
Note: if either the rate input or rate scale factor are set to 0 the scaling will be 1:1 i.e. a 1Hz input
will give a display of 1 i.e. it is assumed that there are no scaling factors.
Example: If an encoder sensing revolutions of a shaft puts out 20 pulses per revolution a
RAtE
INPt
of 20 and a
RAtE SCLE
of 60 will give a display in RPM. Note as the display value is
calculated from the ratio between
RAtE INPt
and
RAtE SCLE
settings of
RAtE INPt
= 1
and
RAtE SCLE
= 3 will give the same result.

Period display decimal point selection
Display:
PErd dCPt
Range:
0
,
0.00.02
etc.
Default Value:
0
Period decimal point selection - only seen when
dISP
function is set to
PERd
. Displays and sets
the decimal point for the period display. Note that the decimal point display is tied to the display
range (
dISP RNGE
) function e.g. if the display range function is set to
0.00.02
then the two
decimal place setting will show up as
0.00.02
and one decimal place will show as
0.00.1
.

Period input scale factor
Display:
PERd INPt
Range:
Any display value
Default Value:
1
Period input scale factor - only seen when
dISP
function is set to
PERd
. Displays and sets the
number of time period to be used with the period scale function to generate the display scaling.
See examples later in this chapter and formula below.
7.33
Period scale factor
Display:
PERd SCLE
Range:
Any display value
Default Value:
1
Period scale factor - only seen when
dISP
function is set to
PERd
. Displays and sets the scale
factor to be used with the period input setting. To calculate the display value the input frequency
and hence the period of this input needs to be known. Scale and input work together to produce
a display as follows:
Display =
Input period (seconds)
×
PERdSCLE
PERd INPt
Note: the displayed value is also affected by the decimal point and display range settings.
