Case where Command Is Given from Input Terminals [A] and [B]
To use the input terminals [A] and [B] of the main body as a pulse string input frequency command, set
[CA-90] to 01: command.
A pulse string given as input to the input terminals [A] and [B] can be used as a frequency command /
PID feedback value in each control mode.
Set an input pulse frequency that corresponds to the maximum frequency to the pulse string frequency
scale [CA-92].
The pulse string input values to the input terminals [A] and [B] can be monitored with [dA-70].
Precautions for Correct Use
• Start/End function of analog input cannot be used. To limit the pulse string input frequency,
use the pulse string frequency bias size [CA-94], the pulse string frequency upper detection
limit [CA-95], and the pulse string frequency lower detection limit [CA-96]
• When the pulse input frequency is below the pulse string frequency lower detection limit
[CA-96], it is regarded as 0 Hz in the processing.
• Slow start if the pulse string frequency lower detection limit [CA-96] is set to a high value.

Description
Frequency command from pulse string input
(input terminals [A] and [B])
pulse train input A
pulse train input B
Used for frequency command
Mode 0: 90° phase difference pulse string
Mode 1: Forward/Reverse rotation command
and rotation direction
Mode 2: Forward rotation pulse string and
reverse rotation pulse string
Input a pulse string frequency that corresponds
to the maximum frequency.
A filter is applied to the input of the pulse string
frequency.
A bias is applied to the input of the pulse string
frequency.
The output of the pulse string frequency input is
limited.
In outputting the pulse string frequency input,
pulses with the frequency lower than the limit is
set to 0.0%.
