11.9 Address B
This address is used to set the number of pulses.
The actual number of pulses is set by the product to the pulse number multiplication factor and the number of pulses
sets at address 9.

Number of pulses
11.9.1 Number of pulses
Set the number of pulses to drive the motor. D0 to Db can be set a pulse in a range of 0 to 4095 pulses.
If the pulse number multiplication factor is set to a value other than 1 at address 9, the number of pulses set here is
multiplied by the set multiplication factor (m).
The number of pulses is internally multiplied by (m) and then counted. If it is set to output pulses to EXT
1
(EXT
2
in
the case of address F), the number of counts output is the set value itself (0 to 4095 x m) .
The number of pulses indicates the number of pulses per pulse period regardless of the driving mode (micro step, 1-
2 phase excitation, or 2-phase excitation). Therefore, the number of revolutions of the motor differs depending on the
driving mode, even if the number of pulses is the same.

Remark
m indicates the set value of the pulse number multiplication factor of address 9. If the value of the twelve-bit,
D0 to Db, is 0, no pulse is output and the driving state is maintained.
