LEAD / LEAD FREQUENCY P1/1
Cnt Mode FI1
Count Mode FI1 (CP-260) identifies the type of encoder that is connected to Frequency Input 1. The “Quad x4”
setting is for a quadrature encoder that gives 4 counts per pulse and also gives direction information. The Incremental
selection is for a single channel encoder, which gives 1 count per pulse but does not give direction information.
2 = Incremental
1 = Quad x4 (default)
PPR FI1
Pulses Per Revolution Frequency In 1 (CP-261) is the number of pulses in one revolution of the encoder device that is
connected to Frequency Input 1. The value may be called Counts, Lines, or Pulses by various encoder manufacturers.
Do NOT multiply by four for quadrature encoders.
FI1 Pulses
FI1 Pulses (CP-262) is used to scale the Frequency Input 1 in EU’s and EU/Tm. Enter the number of pulses that
corresponds to the number of EU’s that are entered in EU FI1 (CP-263).
EU FI1
EU FI1 (CP-263) is used to scale the Frequency Input 1 in EU’s and EU/Tm. Enter the number of EU's that corresponds
to the number of pulses that are entered in FI1 Pulses (CP-262).
LdSyncPolarity
Lead Sync Polarity (CP-264) is a selection that determines the polarity trigger direction of the Lead Sync pulses. The
Lead Sync input can be programmed to trigger on signals going from a low to high voltage level (positive going) or
from a high to low voltage level (negative going).
2 = Falling edge triggered (negative going)
1 = Rising edge triggered (positive going) (default)
Time Base
Time Base (CP-209) is the denominator, which represents the time (Tm) in the EU/Tm equation. The equation scales
the Frequency Inputs (FI1 and FI2) to EU/Tm.
3 = per Hour
2 = per Minute (default)
1 = per Second
FI1 Hz
Frequency Input 1 Hertz (MP-01) displays the current frequency of the Frequency Input 1, in Hertz.
FI1 RPM
Frequency Input 1 RPM (MP-02) displays the current speed of the Frequency Input 1 encoder in RPM, based on PPR
FI1 (CP-261).
Ld EU/Tm
Frequency Input 1 Engineering Units per Time (MP-05) displays the current speed of the Frequency Input 1 in the
Engineering Units per Time (EU/Tm) relative to the Pulses FI1 (CP-262), EU FI1 (CP-263) and Time Base (CP-209). The
placement of the decimal point is the same as the placement of the decimal point in EU FI1 (CP-263).
Ld Posn
Lead Position (MP-10) displays the present value of the Lead Position in Engineering Units, as specified by Pulses
FI1 (CP-262) and EU FI1 (CP-263). The placement of the decimal point is the same as the placement of the decimal point
in EU FI1 (CP-263).
