<Description>
• When speed is continuously changed with the speed change command being set to “1,” “pulse count setting buffer,
lower” is used to set the number of pulses to be added.
• While the speed change command is “1,” the lower 20 bits of 2 words in the set value data area are used as speed
data.
• For writing in the pulse count setting buffer, the remaining 12 bits of the set value data area are used.
a) Pulse count setting buffer, lower : 12 bits (bit 00 to bit 11)
b) Pulse count setting buffer, middle : 12 bits (bit 12 to bit 23)
c) Pulse count setting buffer, upper :
8 bits (bit 24 to bit 31)
Points of use:
· In writing the lower data in the pulse setting buffer, the set number of pulses are added to the command pulse
register.
For signed data, the signal when the lower data was written takes effects.
· Sample pulse output at 250kHz:
12 bits = 4095 / 250kHz = 16ms
For a write of 16ms less, operation is possible only with the lower buffer.
· Writing data from the CPU module into the pulse count setting buffer is enabled only in the pulse generation
mode.
