[Description]
1. If bit 5 in D1846 (D1926, D2006) is set to ON, a manual pulse generator mode will be activated.
2. A manual pulse generator generates A/B-phase pulses that are sent to the input terminals A0±/B0±
(A1±/B1±). The relation between the position of the axis specified and the input pulses generated by
the manual pulses used is shown below.

If a positive limit switch or a negative limit switch is enabled when a manual pulse generator is operated,
the generation of pulses will stop. If a positive limit switch is enabled, positive-going pulses will be
inhibited, and negative-going will be allowed. If a negative limit switch is enabled, negative-going
pulses will be inhibited, and positive-going switch will be allowed.
3. The speed output is determined by the frequency of input pulses generated by a manual pulse
generator and an electronic gear ratio.

Frequency of pulses generated by the manual
pulse generator for the axis specified
[Description]
1. The value in (D1861, D1860) ((D1941, D1940), (D2021, D2020)) indicates the frequency of pulses
generated by the manual pulse generator for the axis specified. It does not vary with the values in
D1858 (D1938, D2018) and D1859 (D1939, D2019).

Number of pulses generated by the manual
pulse generator for the axis specified
[Description]
1. The value in (D1863, D1862) ((D1943, D1942), (D2023, D2022)) indicates the number of pulses
generated by the manual pulse generator for the axis specified. If the pulses generated by the manual
pulse generator for the axis specified are clockwise pulses, the value in (D1863, D1862) ((D1943,
D1942), (D2023, D2022)) will increase. If the pulses generated by the manual pulse generator for the
axis specified are counterclockwise pulses, the value in (D1863, D1862) ((D1943, D1942), (D2023,
D2022)) will decrease.
2. The value in (D1863, D1862) ((D1943, D1942), (D2023, D2022)) does not vary with the values in
D1858 (D1938, D2018) and D1859 (D1939, D2019).

Response speed of the manual pulse generator
for the axis specified
[Description]
1. If the response speed set is high, the pulses output happen almost at the same time as the pulses input
by the manual pulse generator used.
2. If the response speed set is low, the pulses output follows the pulses input by the manual pulse
generator used.
