FOLLOWER / FOLLOWER FREQUENCY P1/2
Cnt Mode FI2
Count Mode FI2 (CP-265) identifies the type of encoder that is connected to Frequency Input 2. The “Quad x4” setting
is a for 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 FI2
Pulses Per Revolution FI2 (CP-266) is the number of pulses that are produced during one revolution of the encoder (or
motor or any other rotating part of your machine) that is connected to Frequency Input 2. This value is only used to
calculate RPM information for FI2 RPM (MP-04).
FI2 Pulses
Frequency Input 2 Pulses (CP-267) is used to scale the Frequency Input 2 in EU’s and EU/Tm. Enter the number of
pulses that corresponds to the number of EU’s that are entered in EU FI2 (CP-268).
EU FI2
EU Frequency Input 2 (CP-268) is used to scale the Frequency Input 2 in EU’s and EU/Tm. Enter the number of EU's
that corresponds to the number of pulses that are entered in FI2 Pulses (CP-267).
FbSyncPolarity
Feedback Sync Polarity (CP-269) is a selection that determines the polarity trigger direction of the Feedback Sync
pulses. The Feedback 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
FI2 Hz
Frequency Input 2 Hz (MP-03) displays the current frequency of the Frequency Input 2, in Hertz.
FI2 RPM
Frequency Input 2 RPM (MP-04) displays the current speed of the Frequency Input 2 encoder in RPM, based on PPR
FI2 (CP-266).
Fb EU/Tm
Frequency Input 2 Engineering Units per Time (MP-06) displays the current speed of the Frequency Input 2 in the
Engineering Units per Time (EU/Tm) relative to the Pulses FI2 (CP-267), EU FI2 (CP-268) and Time Base (CP-209). The
placement of the decimal point is the same as the placement of the decimal point in EU FI2 (CP-268).
Fb Posn
Feedback Position (MP-20) displays the present value of the Feedback Position in Engineering Units, as specified by
Pulses FI2 (CP-267) and EU FI2 (CP-268). The placement of the decimal point is the same as the placement of the
decimal point in EU FI2 (CP-268).
