Omron FQM1-CM001 ユーザーズマニュアル

With ACC(888) and PLS2(887), the acceleration/deceleration rate’s
speed-change cycle can be set to 2ms or 1 ms. Also, the acceleration/decel-
eration rate can be set between 1 Hz and 9.999 kHz. Refer to 7-6-11 Acceler-
ation/Deceleration Rates in ACC(888) and PLS2(887) Instructions for more
details.

Pulses are output according to the clock frequency (20 MHz, 10 MHz, 5 MHz,
2.5 MHz, or 1.25 MHz) specified in the System Setup (Pulse Output/Clock).
The clock signal is divided by an integer dividing ratio to create and output the
output pulse frequency. This means that the actual frequency may not be the
same as the target frequency. Refer to the following information to calculate
the actual frequency.

The following information is used to calculate the output frequency.

Target frequency:
Set by user.

Dividing ratio:
An integer set in the dividing circuit used to generate the output pulses at the
target frequency.

Actual frequency:
The actual frequency that is output as generated by the dividing circuit.
