Claim 1:
2. The servo motor drive circuit according to claim 1, wherein the pulse period providing unit comprises: a latch, a latch triggering unit and a period control unit;
the period control unit is connected to the latch, and is configured to receive a pulse period update signal, and send a pulse period value of a next pulse period to the latch in response to the pulse period update signal;
the latch triggering unit is connected to the motion controller and the latch, and is configured to receive a signal indicating end of a current pulse period, or receive a latch signal from the motion controller, and send a latch control signal to the latch at the beginning of each pulse period in response to the signal indicating the end of the current pulse period or the latch signal;
the latch is configured to receive the pulse period value from the period control unit in response to the latch control signal, and send the pulse period value received from the period control unit to the timer and the first comparing unit; and
the motion controller is further configured to send the latch signal to the latch triggering unit when a first pulse period starts.
