Appendix C: Parameter Summary Numeric Quick Reference (continued)
Minimum Value: 1 Maximum Value: 2
Default Value: 1 Units: Coded
CP-261 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.
Minimum Value: 1 Maximum Value: 60000
Default Value: 60 Units: Pulses/Rev
CP-262 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).
Minimum Value: 1 Maximum Value: 999999
Default Value: 60 Units: Pulses
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).
Minimum Value: 0.0001 Maximum Value: 999999
Default Value: 1.0 Units: EU
CP-264 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)
Minimum Value: 1 Maximum Value: 2
Default Value: 1 Units: Coded
CP-265 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)
