[Explanation of pulse output operation]
Pulses are output using a duty of 25% fixedly.
When using the PLS +SIGN method, pulses will be output approx. 300 us later after the output of direction
signal. (The characteristics of a motor driver is considered.)
Method of acceleration/deceleration and initial speed
When the deceleration stop is requested during acceleration, deceleration is performed with the same slope
of the deceleration time from the target speed.
In this instruction, the operation is processed giving the acceleration/deceleration time priority.
The initial speed may be corrected to enable accelerating/decelerating within the specified time.

・Error flag (R9007):
・Error flag (R9008):
− Turns on when the control code or frequency is out of the settable range
(when the instruction is started).
− Turns on when the area specified using the index modifier exceeds the limit.
− Turns on when n is out of the specified range.
− Turns on when the pulse output of the specified channel is not set by the
system register.
