Pulse cycle
11.8.1 Pulse cycle
Twelve bits, D0 to Db, are used to set the pulse cycle per step.
The pulse cycle can be set in a range of 0 to 8190
μ
s at a resolution of 2.0
μ
s.
If all of the twelve-bit is 0, no pulse is output and the driving status is maintained.
The pulse period indicates the time per step 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
.
