In the Perception software the event bits are combined within one channel and
labeled as CH1_1 through CH1_64. The counter/timer channels are referred to
as CH2 through CH4.
For frequency measurements, the counter/timer channels use an additional
gate-clock to create a time-interval (gate-time) in which pulses are counted. The
gate-time determines the possible resolution of the measurement. The
minimum gate-time is 1 μs, the maximum gate-time is 10 s.
Counter input The counter input is the actual signal input. The counter will be
incremented on each rising edge of this signal. The maximum input frequency
is 10 MHz.
Direction The direction signal determines if the counter will be incremented
(direction = "0"), or decremented (direction = "1") on each rising edge of the
counter input.
The actual mode of the counter/timer channel is selected in the Perception
software. In Perception the RPM is derived from the measured frequency.

12.11.6 GN6470 and GN4070 Quadrature (position) mode pinning

When in quadrature mode Event Bit 53 through 63 are used to provide the
position measurement capability by measuring the signals as provided by
quadrature encoders. These bits are located on the bottom connector as
follows:
