Defines the maximum frequency of the output for both frequency and PWM ouput modes as set by
Digital I/O 01 mode
(08.031). For frequency mode (
Digital I/O 01 mode
(08.031) = 2 ) the choice of
maximum output frequency depends on the requirement of the output. Due to limitations in the hardware, higher output frequencies do not offer the best resolution at the top end of the frequency range.
The table below indicates the resolution at the programmed maximum frequency:

This bit should be set to 1 if a higher accuracy is required than that defined in
Maximum Reference Frequency
(03.043). If
Frequency Input High Precision
(03.042) = 1 then the frequency input
measurement window is doubled. This doubles the accuracy of the frequency input measurment but increases the response time by two also.
If
Frequency Input High Precision
(03.042) = 0 then the frequency input measurement window is similar to Commander SK with better response time.

RW
Defines the maximum frequency expected at the frequency input. The time the frequency is measured over is defined by
Measurement Time = 2048 / Maximum reference frequency
With a maximum measurement time of 0.341 seconds.
2048 is used to give the measurement more stability. The output is 10 bits.
Maximum reference frequency of less than 6kHz will have a lower resolution.
