Pulse output instructions
speed. This means that the values for acceleration time and deceleration time
will not be changed whereas the values for initial speed and final speed may be
corrected by the pulse output instruction to enable acceleration and deceleration
within the specified time. The modified values are written to data registers which
can be accessed using the system variables
sys_iPulseChannelxCorrectedInitialSpeed and
sys_iPulseChannelxCorrectedFinalSpeed (where x=channel number).
Select one of two different operation modes:
Mode with no target value (type 0): Pulses are output in accordance with the
conditions set in the DUT as long as the execution condition is TRUE. A
decelerated stop begins whenever the execution condition is FALSE.

Target value match stop mode (type 1): Output stops when the target value is
reached. Set this mode in the control code, and specify the target value (an
absolute value) in the DUT. A decelerated stop is performed when the target
value has been reached. Deceleration is performed within the specified
deceleration time.

Changing the target speed during pulse output
If the elapsed value crosses over the acceleration forbidden area starting position
(e.g. sys_diPulseChannel0AccelerationForbiddenAreaStartingPosition) during
acceleration, acceleration cannot be performed.
The deceleration speed cannot be lower than the corrected final speed.
